Component for shredding device and shredding device

The invention relates to a component for protection against abrasion in a

Traverse of a crushing device for crushing crushed material, wherein the crushing device is particularly preferably designed as a gyratory crusher or a cone crusher. Furthermore, the invention relates to a system, a

Crushing device and a use.

The shredding device is particularly intended for shredding

Crushed material such as hard rock or raw materials in the stone and earth industry, in ore and natural stone processing, in mining and/or in the cement industry, preferably with an input power in the range of 50 to 2000 kW.

In particular, the crushing device is a crusher. The crusher is used to

Crusher is used for crushing brittle and hard materials. Brittle or hard materials include rock, for example. A crusher is used when impact crushing is not possible due to the high compressive strength of the

crushed material is no longer possible. Impact crushing is often used in

Mining operations and limestone quarries are no longer possible.

When using the shredding device, a

In the flow of material to be crushed that is to be fed into a crusher housing. Even if extremely hard materials such as martensitic steel or hard metals are used on the crossbeam, these are worn away at the crossbeam through regular contact with the material to be crushed and then have to be repaired or replaced.

It is known that the traverse is provided with a cavity that is essentially directed upwards. Crushed material can collect in the cavity, which

“2- BE2022/5720 the underlying section of the traverse is protected automatically or autogenously. The cavity is typically formed as a separate component on the

Traverse is provided, which is attached to the traverse. Also known are

Solutions in which a housing part of the traverse itself is connected to a

Cavity is exchanged. It is known to replace a storage cover of an upper

Storage of a shredding tool of the shredding device with the

cavity by providing it with a raised edge or a

parapet, which was used in the original manufacturing process of the

Storage cover is also manufactured.

In the previously described solutions with the cavity, the edge of the

Cavity or the parapet is still exposed to abrasive wear from the crushed material. Because a build-up welding of the parapet to restore the

Cavity is usually rejected for quality and stability reasons, it is necessary that the component with the cavity must be replaced regularly. For example, the entire bearing cover must be replaced, which entails considerable costs. It may also be necessary for large and actually still functionally intact housing parts of the traverse to be dismantled and/or replaced.

Therefore, an object of the invention is to provide solutions that overcome the disadvantages of

State of the art technology can avoid or at least substantially reduce these risks.

In particular, it is an object of the invention to improve the known

To protect crushing devices in the area of the traverse better and more cost-effectively against abrasion wear and to improve the cost of initial equipment or extension of a

to propose a shredding device.

According to the invention, the object is achieved by a component according to claim 1, a

A system according to claim 9, a crushing device according to claim 11, and a

Use according to claim 12. Advantageous developments of the invention are specified in the subclaims.

A component is required to protect against abrasion wear on a crossbeam of a

Shredding device for shredding material proposed,

73 BE2022/5720 in particular wherein the crushing device is designed as a gyratory crusher or a

Cone crusher, wherein the crossbeam is an upper bearing of an eccentrically movable crushing means of a

Crushing tool of the crushing device and at least two

traverse arms, and wherein the traverse arms support the upper bearing.

The component according to the invention has an at least partially hollow cylindrical and metallic base body with a central axis, wherein the

Base body is designed to be placed along the central axis on a

Bearing cover of the upper bearing to form a space limited by the base body

Cavity for shredded material to be provided on the storage cover, and wherein the

Base body at least two receptacles opposite each other with respect to the central axis and each formed along the central axis for

Accommodates one traverse arm each having at least two traverse arms.

In particular, the base body has an opening, e.g. at the front.

In particular, the base body of the component is at least substantially metallic.

In other words, claim 1 basically describes a component with a

Base body proposed, wherein the base body in particular: is hollow cylindrical or tubular at least in sections, comprises predominantly or only metal, has an opening, in particular on at least one end face, with/on a central axis in the middle of the hollow cylindrical shape, and/or can be placed on the cross member or the bearing cover in order to

To provide a cavity for the material to be shredded, which is delimited by the base body, at least substantially above the storage cover, preferably wherein the base body has opposite receptacles for the crossbeam arms on one (front) side or facing away from the cavity to be formed, and preferably wherein the receptacles run at least in one section along the central axis.

Advantageous to the invention and to the preferred embodiments mentioned below

Embodiments is that an existing shredding device with a

The bearing cover can be reinforced or protected against wear with little effort using the component. The proposed component can be mounted on the

Storage lid is placed on top and immediately forms a cavity above

4 BE2022/5720 of the bearing cover or provides them. The component can be simply lifted off and replaced with a new component when it becomes worn. There is almost no wear on the bearing cover because it can be almost completely covered by the shredded material. In addition, it is no longer necessary to replace the bearing cover to provide a cavity on the bearing cover, so that no expensive spare parts are required and no increased effort is required for this replacement. Thanks to the

The mountings also ensure that the component is very securely positioned on the crossbeam, even if it is not attached to the crossbeam. The mountings provide protection against twisting and tilting for the base body. Another advantage is that the bearing cover is protected against wear not only on the top but also on the sides. This increases the service life of the bearing cover or the upper bearing many times over. The component according to the invention also enables worn parts to be replaced on the

Shredding devices can be replaced more independently.

In a simple case, the base body can be a pipe. The

The base body is designed to be radially symmetrical, at least in sections, around the central axis.

The base body can be provided on one side (in particular one side of two sides along the central axis) with opposite receptacles (in particular on the said

side across the central axis opposite receptacles). The

Receptacles can be designed as recesses or cutouts on the base body and can be adapted in particular to the traverse arms. The receptacles can be arranged on the base body radially symmetrically to the central axis. The receptacles can be arranged according to modified

Embodiments extend into a main extension axis, wherein the

Main extension axis in particular longitudinally, particularly preferably parallel, to the

central axis of the base body. Alternatively, the

Main extension axis perpendicular to the central axis of the base body.

The base body is preferably dimensioned so that its inner diameter corresponds to a

Outer diameter of the bearing cover corresponds, in particular up to 2%, 5%

or 10% larger. In addition, the base body is preferably adapted along the central axis to the height of the storage cover, so that the base body can provide a parapet on the storage cover opposite the receptacles, which is dimensioned, for example, in the range of 1 cm to 50 cm in height 5. The parapet can be higher, as high as, or lower than the

The bearing cover and a part or section of the base body opposite the recesses - the parapet - delimit the

Cavity on the bearing cover. In particular, the receptacles are arranged opposite or facing away from the cavity to be formed in relation to the central axis.

Particularly preferably, the at least two receptacles are arranged opposite one another at, at least approximately, the same location on the central axis, in particular such that the receptacles are provided on one side of the base body.

Both receptacles can, or the receptacle can each typically encompass and/or enclose something. Typically, something can be accommodated in the receptacle, or something can be inserted into the receptacle, for example a traverse arm. The receptacle can, in particular,

Provide a positive connection of the base body in at least one direction and/or about at least one axis, for example relative to the crossbeam arm. The receptacles are designed in particular such that they can be connected in a positive connection to the crossbeam, in particular to the crossbeam arms.

The receptacle can be understood as a recess, a material recess and/or a cutout. In particular, the receptacle is formed in one piece with and/or on the base body and/or by a contour of the

basic body is formed.

It has proven to be particularly advantageous if the base body partially delimits the cavity on the cross member. In particular, the base body can be designed to delimit the cavity together with the bearing cover.

In particular, the base body is designed to be placed — in particular by means of an opening — on the storage cover in order to form the cavity for the shredded material

-8- BE2022/5720 on the storage cover, wherein the base body at least partially or only partially delimits the cavity. The storage cover can

Cavity can also be partially limited. The

Storage cover is basically a provision of a bottom of the cavity, which will wear little or hardly at all due to the mostly stationary material to be shredded.

In this respect, a slim or material-saving component can be provided because the bearing cover also encloses part of the cavity. In other words, the base body itself does not have to have the cavity, but can have it - preferably in

Cooperation with a part of the crushing device, in particular with the traverse, particularly preferably with the storage cover and/or with the

Traverse arm -— partially limit the cavity. However, the base body can alternatively limit the cavity completely.

Opening centrally or on the central axis. The

Hollow cylinder shape is well suited for placing on a storage lid, whose

The peripheral shape of an inner surface can at least substantially correspond to the hollow cylindrical shape.

In a simple case, the opening is a recess in the base body, in particular a hole and/or through hole. The

Central axis typically in the middle of the opening. The opening is usually round and/or cylindrical. The fact that the opening is arranged at the front refers in the

Rule on one of two opposite front sides of the base body along the

Central axis. The opening can be accessible on both ends of the base body, but is proposed to be accessible on at least one end.

7: BE2022/5720

The fact that the base body can be placed on the storage cover should be understood in particular to mean that the base body or the opening

Storage cover. There should be a positive connection between the base body and

Storage cover transverse to the central axis when the base body is attached, in particular by means of the opening. The attached base body should therefore not only be able to rest on the storage cover, but should at least be able to essentially enclose it. This requires, for example, that the

Opening or the base body is large enough to accommodate the storage cover.

The cavity is a recess and/or a groove in which

Crushed material — for example loose rock — can be deposited if the cavity is essentially facing upwards. The cavity does not have to be fluid-tight at the bottom. Water that gets into the cavity could therefore flow out downwards. This may be advantageous in order to prevent corrosion damage caused by standing water.

To avoid water or puddles in the cavity.

In a simple case, the recordings are material withdrawals, recesses and/or cutouts of the base body. The base body can be

Mountings must be adapted to the cross-sectional shape of the truss arm if the

The base body is pushed onto the storage cover so that a secure hold on the traverse is possible. The holders can also each have a guide in which a traverse arm can be guided so that the base body is supported. The guide and/or the holder can correspond to the width of a

truss arm or be up to 2%, 5% or 10% larger than the width of the truss arm. The guide and/or the holder can be a

Depth along the central axis that is less than the height of the traverse arm, for example in the range of 10 to 90% of the height of the traverse arm. It should not go unmentioned that in a simple case only a single receptacle can be provided instead of at least two receptacles. This is useful, for example, if the traverse only has one

In particular, the number of shots is dependent on the number of

The base body can be adapted to the traverse arms.

In this embodiment, there should be twice as many mounts as support arms.

-8- BE2022/5720

Typically, the base body has two opposite

front sides, with the edge, the opening and/or the

recordings are arranged in an accessible manner, and in particular where on the other

Another edge is arranged on the front side, which later serves as a parapet or part of the

Cavity. Typically, no receptacles are provided on the other end face or on the other edge, the other edge can have a bevel and/or an opening is particularly accessible there or continuous from edge to other edge.

The metallic base body has in particular at least substantially a

Steel alloy or is made of it. The base body should have a wall thickness transverse to the central axis in the range of 0.5 cm to 10 cm. The

Range between 1 cm and 4 cm for the wall thickness. In particular, the

The wall thickness along the central axis should be selected to be at least substantially, and therefore preferably at least predominantly and/or in the region of the cavity, in particular approximately constant. In particular, the base body can have one or the other edge with a wall thickness of at least 0.5 cm, 0.75 cm, 1 cm, 1.5 cm or more along the central axis opposite the edge.

The crushing means is mounted eccentrically, particularly in the crusher housing. This basically means that the crushing means can be moved eccentrically to a reference point, for example an axis in the crusher housing, particularly in the middle of an external crushing tool or the crusher housing, in a circular motion around this reference point with a constant and/or adjustable distance. The crushing means can rotate during the eccentric movement, but does not have to rotate. In particular, the

Crushing means are mounted eccentrically in a lower area so that they can move, and are mounted centrally in an upper area or upper bearing, i.e. immobile or possibly rotatable, in order to be able to induce a type of tumbling in the crusher housing.

-9- BE2022/5720

The upper bearing of the crushing agent is contained in the traverse. The upper

Bearing typically allows for slight tilting of the axis in space to provide eccentric mobility. The upper bearing also typically allows rotation of the shredding medium. The upper bearing is typically supplied with a lubricant via the traverse arms.

The crushing tool comprises the crushing means, in particular a cone, and usually an external crushing tool surrounding the crushing means. The crushing means typically comprises a conical, in particular funnel-shaped and/or conical, casing for contact with the material to be crushed and a shaft for holding or stabilizing and for storing the casing. The

The casing can also be referred to as a crushing casing. The outer crushing tool can, for example, have a large number of crushing jaws, which can be attached in the crusher housing in a conical or funnel-shaped arrangement. The crushing means and/or the outer crushing tool are/are in particular made up of several parts in order to enable cost-effective replacement. The crushing means can typically rotate and/or move eccentrically, while the outer crushing tool is generally stationary.

The external crushing tool is typically arranged inside the crusher housing and/or enclosing or surrounding the crushing means. The

The shredding tool is preferably designed and constructed to

The outer

The crushing tool therefore usually has a conical and/or funnel-shaped form that encloses the crushing agent. The outer crushing tool can also be made up of several parts, whereby the several parts or several outer

Crushing tools can be attached to the crusher housing. For the sake of simplicity, an external crushing tool composed of several parts is understood to mean a single external crushing tool.

According to a modified embodiment, at least one of the receptacles can have a support surface for resting on a cross arm. The support surface can be at least flat, aligned transversely to the central axis and/or adapted to a surface of the cross arm. It should be ensured that the receptacles are not only point-like or linear, but

-10- BE2022/5720 rest flat on the traverse arms. In particular, both or all

This means that if the traverse arms have inclined and/or non-flat surfaces, the support surfaces on these

Angles or their non-flat shape must be adjusted so that the contact surfaces lie flat. This avoids force peaks and ultimately permanent deformations and/or jamming when vertical forces are transmitted via the component into the

traverse arms.

The support surface and/or the holder can also, at least in sections and

In the side view on the central axis, have a V-shape and/or a roof shape, for example a pent roof shape, a gable roof shape, a

Flat roof shape and combinations thereof. The V-shape and/or roof shape has in particular opposing surface sections and/or is in the

Side view of the central axis and along the central axis essentially concave or formed as a depression. The opposing surface sections or the V-shape and/or roof shape can be used to rest on a roof surface of the

traverse arm, especially if the traverse arm has a

Roof surface with roof surface sections facing away from each other or is covered by them. This ensures good wear protection even for traverse arms that are themselves V-shaped and/or roof-shaped or have such a surface as wear protection.

According to a modified embodiment, at least one of the receptacles can be provided with at least one

Crossbar arm of which at least two crossbar arms have opposite side surfaces. The opposite side surfaces can also be adapted to the side surfaces of a respective crossbar arm. The side surfaces can run at least substantially parallel and/or in an identical or at least similar

Here too, it is important to ensure that surface contact is preferred to point contact. In particular,

Jamming of the component on the traverse is avoided.

According to a modified embodiment, at least one of the receptacles can be designed to receive a cutting tool directed upwards or away from the shredding means and/or from the

-11- BE2022/5720

Traverse facing away from the parapet on the traverse arm at least one further receptacle, in particular arranged in extension of one of the

Side surfaces formed along the central axis and/or pointing along the central axis. The additional receptacle should be understood as a “receptacle in the receptacle”. The additional receptacle does not necessarily serve to hold the traverse arm. In particular, the additional receptacle serves to hold a

The further recording is particularly smaller than the recording. The further

The receptacle can be designed as a notch, slot and/or groove, in particular starting from the receptacle, in particular preferably extending along the central axis. In particular, the further receptacle provides a positive connection of the

base body around the central axis in conjunction with a parapet or a

Parapet element and/or with the traverse arm.

According to a modified embodiment, two further receptacles can be provided in order to be able to accommodate the mostly circumferential parapet at two points. In particular, therefore, at least two of the further receptacles are provided at a distance from one another within the receptacle, preferably opposite one another on or in relation to the support surface. In this way, the parapet is

Abrasive wear on the bearing cover to be released.

According to a modified embodiment, it is provided that the base body has a projection between the at least two receptacles and on the edge, wherein the projection is provided for laterally covering a lower

Part of the upper storage.

If the base body has a projection between the at least two receptacles or on the edge, additional wear protection of the upper

Material to be shredded. Preferably, there are as many projections as there are receptacles, for example two or more projections.

According to a modified embodiment, it is provided that the base body, in particular the projection, has at least one opening pointing towards the central axis and/or at the side, preferably wherein several openings are provided next to one another and/or opposite one another with respect to the central axis.

If the base body, in particular the projection(s), has at least one

central axis and/or lateral opening, a simple

Possibility of fastening to the cross member is provided. The opening can lead into the opening. Several openings can be provided, in particular per projection. If several openings are provided next to each other and/or opposite each other in relation to the central axis, a particularly good and redundant fastening option for the component can be provided.

According to a modified embodiment, it is provided that the base body is intended for fastening to the cross member by means of a pin to be welded, in particular to the opening.

A bolt can be inserted into the opening, brought into contact with the cross member, in particular with a/the lower part of the upper bearing, and then welded to the opening.

The component can be advantageously supplemented if it is part of a system with the component and with at least one metallic parapet element.

System can basically also be understood as a kit or a set.

The aim of the system is to combine the component and the parapet element in a way that is advantageous.

The parapet element is designed to be placed on at least one of the at least two

Traverse arms are provided. The parapet element can also be used as an armliner or

The parapet element is then used to form an upwardly facing parapet on the respective traverse arm

-13- BE2022/5720 is provided to provide a (further) cavity for material to be shredded on the traverse arm.

In particular, the combination of component and parapet element in the proposed system is particularly useful if the base body is attached to the

The other mounting also has the other mounting, because then the parapet element can be easily accommodated here. This way, the component and the

Parapet elements merge into one another and protect the traverse even better.

In addition, the component can be replaced separately from the parapet element as it is usually the most subject to wear and tear compared to the parapet element.

In a simple case, the parapet element is a vertical or raised

Walled component for mounting on a traverse arm. The

Walls can be arranged on a base plate, in particular in one piece, whereby the base plate can rest on the surface of the respective traverse arm and/or can be fastened. The walls can form the parapets.

The parapet element can have the cavity or at least partially be attached to the

Traverse. The parapet element can be attached to the

A pin connection and/or a screw connection must be provided for the traverse arm.

For example, the parapet element can be connected to the

The traverse arm must be screwed and/or pinned so that the pinning or

Screw connection is not in continuous contact with the material to be shredded.

If the component therefore has a base body and one or more

Parapet elements, an advantageous multi-part design is provided. The multiple parts can be replaced independently of one another when they become worn.

In particular, the bearing cover does not need to be replaced regularly because it is well protected against wear by the base body.

In a further solution according to the invention, a shredding device is proposed. This shredding device is designed for shredding

crushing material, in particular as a gyratory crusher or a

Cone crusher and has

-14- BE2022/5720 — a crusher housing, — a crushing tool arranged in the crusher housing with an eccentrically movable crushing means and with a

outer crushing tool surrounding the crushing means, — a crossbeam with an upper bearing of the crushing means, with at least two supporting the upper bearing on the crusher housing

Crushing device is designed as a gyratory crusher or a cone crusher.

Furthermore, a method is disclosed. The disclosed method is intended for

After placing the base body on the upper part, it can be attached to the

Storage can be done by pinning and/or welding. This way, the component can be secured against accidental removal without significantly complicating its interchangeability.

The process can be further developed by applying a metallic

Parapet element on one of the truss arms to form an upwardly pointing parapet on the respective truss arm to create a cavity for

The parapet element or parapet elements are preferably placed on the support cover before the base body is placed on the support cover. This allows the base body to form a positive connection with the parapet element, but in particular to create an overlap on/with the parapet element in order to further protect the traverse.

In the system, in the crushing device, in the use as well as in the disclosed method, it is particularly advantageous that the component

In Fig. 1A, a crushing device 2 for crushing material to be crushed is shown. The crushing device 2 is a gyratory crusher. The gyratory crusher has a crusher housing 20, a crushing device arranged in the crusher housing 20

Crushing tool 10 with an eccentrically movable

Crushing means 12 and an outer crushing tool 14 surrounding the crushing means 12 in the form of a plurality of crushing jaws. The

In this case, the comminution means 12 is a cone.

Furthermore, the gyratory crusher has a cross member 4 with an upper bearing 16 of the

crushing means 12, with two cross arms 6 supporting the upper bearing 16 on the crusher housing 20 and with a bearing cover 18 of the upper bearing 16 closing the upper bearing 16 on the top. The

Traverse arms 6 are fixed to the upper bearing 16, for example monolithically connected to the upper bearing 16. The bearing cover 18 is basically designed to be removable.

The bearing cover 18 closes a bearing mechanism inside the upper bearing 16. When the bearing cover 18 is removed (not visible), sections of the comminution means 12 and/or inner parts of the upper bearing 16 that are sensitive to the material being comminuted are exposed in the cross member 4 and must be protected in particular by the bearing cover 18.

The bearing cover 18 is subject to continuous abrasive wear by introduced

The material to be shredded is supplied. In other words, the storage cover 18 is sacrificed. This reduces the wall thickness of the storage cover 18 and there is an increasing risk that the storage cover 18 will be damaged, for example broken. In this respect, the storage cover 18 must be regularly inspected and maintained, in particular individually repaired and/or replaced.

-18- BE2022/5720

The wear of the bearing cover 18 is typically counteracted by the bearing cover 18 having a very large wall thickness in the sense of reinforcement or armoring, for example in the range of 1 cm to 10 cm.

In addition, a protruding cross with a substantially flat surface

Be arranged in the middle of the storage cover 18, as is the case here. The cross fulfils a structural function, so that the storage cover 18 in vertical

Collision with the material to be shredded can be less easily pressed in or deformed, and so that the material to be shredded can also hit the bearing cover 18 sharply and thereby be broken. The cross also has the function of losing its shape and/or changing its shape as the bearing cover 18 wears. In this way, the wear of the bearing cover can be recognized with the naked eye, which is not the case with a rather smooth upper side.

Storage cover 18 (not visible) would not be so easy.

When filling the gyratory crusher with crushed material, lateral collisions of the crossbeam 4 with crushed material also occur, in particular at a lower part 17 of the upper bearing 16. In this case, it has proven useful to use

Welds and/or material reinforcements to “armor” the bearings; this “armor” is visible here at the arrow to reference number 17. In this case, there are five welds running horizontally around the bearing 16, which are arranged one above the other in a scale-like manner. Of course, other shapes or numbers of

Material reinforcements or welds are conceivable, which differ from a rather smooth

surface in three dimensions. As the welds change and/or lose their shape with continuous wear, the

Opening 36, in contact with the bearing 16, in particular with the lower part 17 of the

Storage 16 and/or with the storage cover 18.

The cavity K thus formed or provided serves to hold the shredded material on the storage cover 18. The storage cover 18 therefore no longer comes into continuous contact or collision with the shredded material, but rather the shredded material essentially remains at rest on the storage cover 18.

This means that there is little or no wear on the bearing cover 18, especially on the upper bearing 16 or on the cross member 4.

Base body 32, in particular the opening 36 or the inner surface 48, not even

-24- BE2022/5720 should be in contact with the bearing cover 18 all the way round; a gap of up to 5 mm is even beneficial for assembly and disassembly and is not detrimental to the

Wear and tear caused by shredded material. This can cause liquid to drain off.

Not shown is an embodiment in which the base body 32 has a

intermediate floor, which is adapted, for example, to a shape of the

storage cover 18 and/or which delimits an upper cavity K. In this way, the

The base body 32 itself already has the cavity K and not only in

interaction with the bearing cover 18. In particular, the

Opening 36 can be continuous as shown in Fig. 2-4 on the base body 32 or can be a blind hole. However, this does not change the principle that the

Component 30 or system 31 can improve an existing shredding device 2 according to the prior art in a simple and cost-effective manner, namely without the existing bearing cover 18 of the upper bearing 16 on the shredding device 2 having to be replaced.
