Definitions

  • the invention relates to a roller press or high-pressure roller press, in particular a material bed roller mill or compacting machine, with two press rollers rotatably mounted in a press frame (and driven in opposite directions), between which a pressure zone is formed with a roller gap arranged at the level of the roller axes, the gap width of which is formed during the Operation is variable, with one of the press rollers being designed as a fixed roller and one of the press rollers being designed as a loose roller that is movable relative to the fixed roller, the loose roller being adjustable against the fixed roller via force generating means with a gap width (W) that changes during operation, the pressure zone between The press rolls (or the roll gap) are delimited on the roll end by (two) limiting plates arranged laterally next to the press rolls, the limiting plates being attached to the press frame in such a movable and force-loaded manner (or pre-stressed) that the limiting plates are secured during operation of the roller press (e.g . B. in the course of a tilting of
  • Such a roller press is used in particular for the comminution of material, in particular highly abrasive material, for example ore, cement clinker, slag or ceramic base materials, or for the compaction of e.g. B. fertilizers.
  • the roller press is used e.g. B. high-pressure comminution and is then also referred to as good bed roller mills.
  • the roller press can also be used to compact material.
  • bed roller mills the individual particles of the feed material are not crushed like in a crusher broken between the surfaces of the two rollers, but rather they are pressed under high pressure in a bed of material or material and are therefore shredded highly efficiently.
  • the feed material is pressed between the rollers into a slug (e.g. when compacting fertilizers).
  • the two rollers of a roller press are driven in opposite directions.
  • One of the press rollers is designed as a fixed roller and the other press roller is designed as a loose roller, the loose roller being movable relative to the fixed roller, namely adjustable against the fixed roller with a variable gap width.
  • the loose roller has force generating means, e.g. B. hydraulic and / or pneumatic, adjustable against the fixed roller and thus supported, as it were, against a hydro-pneumatic spring.
  • the gap between the rollers adjusts automatically until a certain pressure is applied between the rollers.
  • the gap width is determined by the ratio of the pressing force of the hydraulic system to the reaction forces emanating from the material to be processed.
  • the roll gap or the printing zone is delimited laterally by boundary plates which are attached to the press frame and which in practice are also referred to as "cheek plates” or hopper boundaries or hopper boundary plates.
  • Their shape is often adapted to the pressure zone (the “filling funnel”) between the press rollers, which tapers in a funnel-shaped manner in the direction of rotation of the press rollers or in the conveying direction.
  • the limiting plates are subject to high levels of wear. It is therefore known to provide the boundary plates with a wear protection layer. This is how e.g. B. in the DE 10 2018 113 440 A1 a roller press is described in which, on the one hand, plate-shaped wear protection elements and, on the other hand, pin-shaped wear protection elements are used in the high-pressure zone for the wear protection layer of the boundary plates.
  • WO 2006/124425 A1 proposed to provide a large number of movable elements arranged in a matrix on the side boundary plates, which z. B. can be designed as roles.
  • the rollers distributed like a matrix on the "cheek plates", are intended to allow the surface to move with the material and thus reduce friction and consequently wear.
  • the side limiting plates attached to the press frame are dispensed with and instead, limiting elements, e.g. B. attached circumferential flanges, which are non-rotatably connected to one of the rollers, so that these side flanges rotate with the rollers and are consequently moved at the speed of the material.
  • limiting elements e.g. B. attached circumferential flanges, which are non-rotatably connected to one of the rollers, so that these side flanges rotate with the rollers and are consequently moved at the speed of the material.
  • the disadvantage is that these side flanges do not easily allow the loose roller to be tilted, so that a homogeneous material feed across the machine width must be ensured.
  • Such a roller mill with side flanges to limit the roll gap is z. B. in the DE 37 01 965 A1 described.
  • the DE 10 2018 108 690 A1 elastic deformation of the flanges is permitted.
  • such measures are relatively complex.
  • lateral filling shaft boundaries are provided that are provided with special anti-wear agents.
  • a frame can be inserted into a section of the filling shaft boundary plates, in which several rollers are arranged one below the other (cf. DE 665 141 ).
  • roller presses are also known for compacting directly reduced iron at high temperatures (cf. EP 2 314 723 B1 and EP 3 358 024 A1 ).
  • Side “cheek plates” are also provided for these presses.
  • the “cheek plates” have indentations in the upper area that allow the screw conveyors to be arranged at an angle.
  • a roller press is also known in which at least one of the rollers is provided with a profiling, which is intended to ensure, particularly in the edge zones, that the material there is also drawn into the roller gap to the same extent as in the central area of the rollers.
  • the DE 36 35 762 A1 describes a roller mill in which the end walls of the feed shaft are provided with special storage elements that should have an open honeycomb structure.
  • Boundary plates are described for the briquetting of material with a high moisture content, the boundary plates having a curved area into which special bodies are integrated so that drainage channels are formed.
  • the invention is based on the object of creating a high-pressure roller press, in particular a material bed roller mill or compacting machine, of the type described above, which is characterized by improved operation and in particular a high throughput with a simple structure.
  • the invention teaches in a generic high-pressure roller press, which is equipped with force-applied limiting plates, that (only) a single roller is attached to the limiting plates at the height of the roller gap, which is rotatably mounted about its roller axis and which controls the roller gap laterally limited, with the width of the roll being greater than the maximum gap width of the roller gap.
  • Each of the two side boundary plates is therefore provided with a single roller, so that there are (only) two rollers in total.
  • the roll axes are oriented perpendicular to the roll axes or perpendicular to the fixed roll axis of the fixed roll (and perpendicular to the direction of transport of the material through the roll gap).
  • the invention is initially based on the knowledge that it is advantageous to provide the basically known, force-applied boundary plates (cheek plates), so that - unlike the solutions with boundary flanges on a roller - a skewing of the rollers or a Inclination of the loose roller relative to the fixed roller can be permitted.
  • This configuration has the great advantage that overloading of the machine or the filling hopper limiting devices is reliably avoided without having to ensure a uniform feed of the feed material across the roller width.
  • the friction in the area of the high-pressure zone is reduced by having a single roller in each of these push-back boundary plates Transport roller is integrated.
  • Such a single roller in the area of a boundary plate means that not several rollers are arranged one above the other, but rather only a single roller is rotatably arranged on the boundary plate in the area of the high-pressure zone.
  • this embodiment does not exclude the possibility that such a single roller is composed of several roller sections or roller parts that can be rotated side by side about the same axis.
  • these rollers or roller sections which may rotate side by side about the same axis, preferably have a (one-piece) roller jacket that is continuous over the width and circumference, so that in particular there is no risk of material getting stuck in a gap between the individual rollers or roller sections.
  • the limiting plates - in addition to the roller provided in each case - each have a material guide pocket that is integrated into the limiting plate, specifically above the roller attached to the limiting plate, so that the roller comes over this material guiding pocket from above Material is acted upon or can be acted upon.
  • Recessed material guide pocket means that the pocket is set back from a front plane of the limiting plate, the front plane being the plane of the limiting plate facing the roller end face and oriented parallel to the roller end face.
  • the material guide pocket consequently has a rear wall which is set back from this front plane and is (at least) partially spaced from the front plane and which is preferably curved.
  • the material guide pocket is funnel-shaped with a width that tapers downwards.
  • the material guide pocket has a depth that tapers downwards, so that overall a funnel-shaped material guide pocket is realized with which the Material is fed from above to the transport roller attached to the boundary plate.
  • the transport roller on the force-loaded (for example the spring-loaded) limiting plate is therefore particularly important in combination with the material guide pockets.
  • the roller is preferably dimensioned and positioned in such a way that the upper apex of the roller is arranged above the roller axis and/or that the lower apex of the roller is arranged below the roller axis or axes.
  • the two transport rollers attached to the two boundary plates - based on the height - are in the area of Pressure zone of the roller press arranged.
  • the pressure zone is defined as the zone of the working space of the roller press, which extends between the two rollers over a circumferential angle of -5° to +15°, in each case in the direction of the roller gap and in relation to a straight line through the centers of the two rollers.
  • the roll gap is at the height of the roll axes and therefore at a circumferential angle of 0°.
  • the pressure zone is therefore, by definition, the area that lies between +15° above the roller axis and -5° below the roller axis.
  • the transport rollers are arranged in the area of the roller axes and consequently also in the area of the printing zone.
  • the transport rollers are preferably dimensioned and arranged in such a way that the upper vertices of the rollers are arranged within the printing zone (based on the height of the printing zone). Alternatively or additionally, the lower vertices of the rollers are arranged below the pressure zone.
  • the roller axes of the transport rollers are arranged approximately at the height of the roller axis(s).
  • the diameter of the rollers is preferably adapted to the roller diameter of the press rollers in that the roller diameter is at least 5% of the roller diameter, preferably at least 10% of the roller diameter.
  • the roll diameter can be, for example, about 5% to 35%, e.g. B. 10% to 30% of the roll diameter.
  • the roller diameter of the press rollers is typically between 1000 mm and 3000 mm, for example 1200 mm to 2000 mm.
  • the diameter of the (transport) roller can be at least 50 mm, preferably at least 100 mm, particularly preferably at least 200 mm. So the roll diameter can e.g. B. 50 mm to 1000 mm, preferably 100 mm to 600 mm, e.g. B. 200 mm to 450 mm.
  • the width of the (transport) roller is greater than the maximum gap width of the roll nip and consequently greater than the preset zero gap plus at least the distance by which the roll gap opens during machine operation.
  • the width of the roll can be at least 1%, preferably at least 2% of the roll diameter, e.g. B. at least 50 mm, preferably at least 60 mm.
  • the width of the roll is particularly preferably approximately 1% to 10%, e.g. B. 2% to 8% of the roll diameter. So the role can e.g. B. a width of 50 mm to 200 mm, e.g. B. 60 mm to 100 mm.
  • Width of the (transport) roll means the width of the (circumferential) working surface of the roll and consequently the width of the roll's bale.
  • the roller should transport additional material from the hopper or material guide pocket above the roller into the gap and consequently convey material into the area of the roll gap. This is achieved, among other things, by appropriately dimensioning and arranging the roller at the height described.
  • the effect can be further improved by providing the roll with a profiled or structured surface (on the roll circumference). So you can e.g. B. pin-like wear elements (so-called “studs”) can be used, which z. B. from the EP 0 516 952 for equipping the roll surface of press rolls of a good bed roll mill or according to DE 10 2018 113 440 A1 can also be used as wear protection elements in the area of boundary plates or cheek plates.
  • the feeding of the material to the rolls via the material guide pockets or material funnels can also be improved by using guide internals that are suitably inserted into the material guide pockets to get integrated.
  • the boundary plates can be provided with additional sealing plates which run parallel to the front plane or in the front plane and partially cover the material guide pocket on the front.
  • rollers without a drive, so that the rollers rotate passively as it were due to the material that is fed in and moved by the press rollers.
  • the rollers are preferably driven (indirectly) via the rollers by pressing the rollers with their peripheral surfaces against the end faces of the rollers. Because the peripheral surfaces of the rollers are in any case larger or wider than the nip, so that the rollers with their peripheral surfaces or bale surfaces (working surfaces) e.g. B. press against the end faces of the rollers by applying force to the limiting plates and thus drive them over the rollers.
  • the rotational speed or the peripheral speed can also be slightly faster than that of the roll surfaces in order to optimize the conveying effect of the material in the roll gap.
  • the preferred implementation of the recessed material guide pockets in the area of the boundary plates also results in material being pushed over the end faces of the rollers into the material guide pockets and via this path into the grinding gap.
  • This has the advantage that the grinding gap is additionally supplied with material. It can be advantageous to additionally protect the end faces of the rollers against wear, so that the measures to reduce wear that are usually used in the area of the peripheral surface of the rollers are optionally provided in the area of the end faces, e.g. B. suitable armor.
  • structuring in the area of the end faces of the rollers can also be useful in order to increase the effect of drawing in material.
  • the figures show a high-pressure roller press 1, which is designed as a material bed roller mill or compacting machine. It has a press frame 2 and two press rollers 3, 4 which are driven in the direction of the arrow and mounted in the press frame. A pressure zone 5 is formed between the press rolls with a roll gap S arranged at the level of the roll axes X, X ', the gap width W of the roll gap S being variable during operation of the roll press 1. Because one of the press rollers is designed as a fixed roller 3 and the other press roller as a loose roller 4, the loose roller 4 having force generating means, e.g. B. hydraulically, can be adjusted against the fixed roller 3 (in a horizontal plane), so that the gap width W of the roller gap S changes within certain limits during operation.
  • force generating means e.g. B. hydraulically
  • the roller gap S or the gap width W adjusts independently along the roller gap until a certain pressure acts between the rollers.
  • the loose roller 4 can tilt relative to the fixed roller 3 about a vertical axis and consequently in a horizontal plane, so that the roller axes X, X 'are always arranged at the same height and consequently in a horizontal plane during operation, However, they can be oriented at a certain angle to each other within this plane.
  • the material is fed from above via a feed chute (not shown) and is drawn into the pressure zone by the counter-rotation of the rollers and is shredded (or compacted) there under the influence of the existing grinding pressure.
  • the pressure zone 5 arranged between the rollers is delimited on the roller end by boundary plates 8 arranged laterally next to the press rollers 3, 4, which in practice are also referred to as filling funnel boundaries or "cheek plates”.
  • These limiting plates 8 are movably attached to the press frame 2, namely subject to force, e.g. B. by springs 9, the application of force acting in the direction of the roller end faces 6.
  • the limiting plates 8 protect against the application of force, e.g. B. can be pushed back against the force of the springs 9. This is important because in such a roller press the already mentioned misalignment of the rollers or a roller 4 relative to one another is deliberately permitted.
  • each of the two boundary plates 8 has a front plane 11 that faces the respective roller end face 6 and is oriented parallel to the roller end face 6.
  • a material guide pocket 12 is integrated into the respective boundary plate 8 above the roller 10 attached to it, which is set back from the previously defined front plane 11, so that the roller 10 can be loaded with material from above via the material guide pocket 12.
  • the material guide pocket 12 consequently has a rear wall 13 which is set back relative to the front plane 11 and is at least partially spaced from the front plane, which in the exemplary embodiment can be seen in both a vertical section Fig.
  • this material guide pocket 12 is in a side view or in a perspective view from the inside (according to Fig. 4 ) is therefore funnel-shaped, ie it has a width B that tapers downwards.
  • the material guide pocket has a depth T that decreases downwards (compare Fig. 2 ).
  • This configuration means that the material is fed via the material guide pockets 12 from above into the area of the two rollers or transport rollers 10 arranged on the side of the nip S. In the front, outer areas of the rollers 3, 4, an excess supply of material arises via the material guide pockets 12.
  • Fig. 2 It can also be seen that the upper vertex 10a of the roller 10 is arranged above the roller axis X or X ⁇ .
  • the lower vertex 10b of the roller 10 is arranged below the roller axis X or X ⁇ .
  • the upper vertex 10a is arranged within the pressure zone 5, while the lower vertex 10b is arranged below the pressure zone 5.
  • Pressure zone 5 is according to Fig. 1 defines the zone of the roller press, which extends between the two rollers over a circumferential angle ⁇ of -5 ° to +15 °, specifically in relation to the connecting straight line through the roller axes X, X '.
  • the pressure zone 5 is therefore, by definition, the area that is +15° above the roller axis and -5° lies below the roller axis X, X '.
  • the roller axis Y of the rollers 10 is z. B. approximately at the level of the roller axes X, X 'of the press rollers 3, 4.
  • the width E of the rollers 10 is in any case greater than the maximum gap width W and consequently greater than the zero gap of the roll gap S plus at least the distance by which the roll gap opens during machine operation.
  • Width E or roll width means the bale width, that is, the width of the working surface of the rolls.
  • the roll circumference and consequently the circumferential surface 7 of the press rolls 3, 4 is generally provided with a special surface finish, e.g. B. provided with a wear-resistant coating or bandage. Details are not shown in the figures.
  • the roller circumference and consequently the peripheral or ball surface 14 of the rollers 10 can also be provided with a wear-resistant coating.
  • the circumferential surfaces 14 of the rollers 10 can therefore be designed to be wear-armored or have wear armor. With this wear armoring of the rollers 10, known measures for wear armoring of the roller surfaces can be used. So you can e.g. B. a large number of bolts can be integrated into the peripheral surface like studs (stud lining).
  • wear armor can be realized from a large number of tile-like wear elements attached to the surface. Wear armor through build-up welding can also be considered.
  • the roller itself is always preferably made of steel and the wear armor made of a hard, wear-resistant material is arranged on the circumference of this roller.
  • the peripheral surface 14 of the rollers can be equipped with a profiling or structuring. Details are not shown. Incidentally, it exists Possibility that the rollers 10 are each driven with a drive. Such a drive is not shown in the figures.
