Definitions
- the invention relates to a multi-roll crusher according to the preamble of claim 1.
- Such multi-roll crushers serve in particular as crushers for crushing mineral crushed material, in particular coal, ore, stone, natural stone, bauxite, marl, clay, oil sand or similar materials. These crushers are intended to bring the material, which arrives with a particle size of up to about 150 mm, to a particle size of generally ⁇ 50 mm. It is important in the comminution of coal, in particular, that it is not or only slightly compressed during the breaking process and essentially maintains its internal structure.
- DE 199 04 867 Al belongs to the prior art a device for crushing mineral crushing material with two crushing rollers, the crushing process between the crushing rollers and provided with crushing organs opposite walls of the crusher housing. There is no breaking process between the two crushing rollers, which rotate in opposite directions.
- the invention is based on the object to propose a multi-roll crusher of the generic type, in which substantially without compression and preferably by shearing the material crushed and in the smallest possible crusher space and the lowest possible machine wear a high throughput is achieved.
- the connecting line (V) of the axes of rotation (R) has at least one kink.
- This kink causes either at a constant distance of the axes of rotation (R), the total width (B) of the crusher space in which the crushing rollers are arranged parallel to each other, can be reduced or that with the same width of the crusher space possibly more crushing rollers can be accommodated and thus the Throughput per total width of the crusher room is increased.
- Arrangement and size of the buckling are chosen so that the smallest possible deflection of the crushed material on its way from the feed opening of the crusher to the passage through the working gap of the wear of crushing tools and crushers is minimized.
- the crushing rollers can basically be used with a smooth surface so untoothed. However, it has also proven to be favorable that the circumference of the crushing rollers uniformly or non-uniformly distributed crushing or cutting teeth of the same or unequal tooth height and / or tooth shape are arranged and that they interact with cutting elements at the top and / or laterally in the upper area are arranged on an anvil bar, which is preferably height-adjustable and / or resiliently mounted in the vertical direction.
- the cutting elements can preferably be arranged on the anvil strip on itself over the entire length of the crushing rollers extending strips, the cutting teeth can engage the crushing rollers in tooth spaces of the strip.
- the multi-roll crusher according to the invention can also be embodied without an in-edge strip or without a cutting element.
- the entire material is comminuted when passing through the working gap between the two crushing rollers or between a crushing roller and crushing teeth on the wall side, wherein the adjustable and / or resilient mounting of the anvil bar prevents interference caused by excessively large or too hard chunks of material.
- To adjust the grain size of the product and the working gap can be adjusted by changing the axial distance of the crushing rollers and / or by changing the distance of the anvil bar.
- According to the required particle size of the product and the cutting teeth of two adjacent crushing rollers can be arranged angularly offset on the roll circumference.
- a working gap and an empty gap alternate over the entire width of the breaker space due to the changing directions of rotation of the breaker rolls.
- the material is essentially conveyed from top to bottom or obliquely down and thereby crushed.
- the crushing or cutting teeth move upwards or obliquely upwards on the circumference of the crushing rollers, so there is no Comminution of the material takes place.
- the gap width of the empty gap is less than or equal to the working gap.
- the cutting teeth of the adjacent crushing rollers can be arranged angularly offset and, if necessary, their peripheral speed synchronized so that the distance between the two rollers can be reduced without teeth of these rollers touching each other.
- the connecting line between the axes of rotation of two adjacent crushing rollers in the region of a working gap horizontally or slightly inclined at an angle ⁇ of up to 30 ° to the horizontal.
- the connecting line in the region of an empty gap can have an angle ⁇ of up to 90 or 75 °, preferably 30 to 60 ° to the horizontal. Large angles .beta. Can be advantageous in particular with crushing rollers of different diameters adjacent to the empty gap. Overall, the angle should be ⁇ ⁇ the angle ß.
- each case two crushing rollers, which form an empty gap between them, as a structural unit on a rocker pivotally and / or displaceably mounted on the housing of the multi-roll crusher.
- This rocker preferably includes right and left outside of the crusher housing arranged and mounted roll carrier, wherein the axes or waves of the associated crusher rollers can be passed through suitable slots of the crusher housing.
- the two belonging to a pair of rollers roller carrier of a rocker can be pivoted together in each case about a parallel to the axes of rotation of the crushing rollers arranged rotational axis, wherein preferably the pivoting of the rocker by a adjustable stop is limited and acts on the rocker a preferably preloaded spring in the direction of a stop.
- Fig. 5 is a partial perspective view of a bar 10 with
- Fig. 6 shows an arrangement of five crushing rollers in a crusher space
- Fig. 7 shows an arrangement of six crushing rollers in a crusher space
- crushing rollers 1, 1 ', 2, 2' are shown as smooth cylindrical rollers, wherein refractive or cutting teeth 4 are readily provided on the circumference of the rollers, as shown in FIGS. 8 to 13 could be.
- no breaking or cutting teeth 4 were drawn for the sake of simplicity.
- the breaking or cutting teeth 4 are particularly useful if, under the working gaps A, A 'in each case over the entire length of the crushing rollers extending anvil strip 3 and outer crushing teeth 14 are present.
- the anvil strip 3 may be provided according to Fig.
- the anvil strip 3 can according to the illustration in Fig. 7 except the cutting bar 7 also at the top cutting elements 5 and in the upper side region also have cutting elements 6.
- the entire anvil strip is preferably vertically or according to their inclination (cf., for example Fig. 2, 6, 12 and 13) adjustable in the transport direction of the material and in particular resiliently mounted by springs 8.
- outer crushing teeth 14 may be arranged, which cooperate with the crushing or cutting teeth 4 on the adjacent crushing rollers 1 ', 2'. These outer crushing teeth 14 may be similar to the anvil strip 3 adjustable and resiliently mounted.
- the simplest embodiment of the multi-roll crusher according to the invention can be explained with reference to FIG.
- the dotted straight line V connects the axes of rotation R of the two crushing rollers 1 and 2 and the axes of rotation R of the crushing roller 2 with the deeper crushing roller I 1 .
- the defined in claim 1 according to the invention kink in the connecting line V is therefore present at the axis of rotation R of the crushing roller 2.
- the connecting line V is extended horizontally up to the walls 12, 13.
- the working gap A see Fig. 3
- the marginal crushing rollers I 1 , 2 1 and the outer crushing teeth 14 are each the working gap A '(see Fig. 3), with the gap width a 1 .
- the sum of the gap widths a and a 1 on the total width B of the crusher space is the decisive measure of the throughput of the multi-roll crusher. The point here is to maximize the sum of these gap widths a, a 1 over the total width B.
- the second decisive measure are the gap widths I and I 'which also extend in the direction of the connecting line V in the region of the empty gaps L, L' (compare FIGS. 2 and 3).
- the empty gap L is here as the gap between two "internal" crushing rollers 1, 2 or 1, 2 'or 2, 1' defined, while the blank gap L 1, the gap between the peripheral crushing rollers 1, 2 and the wall 12, 13, on which no outer crushing teeth 14 are arranged.
- the crushing or cutting teeth 4 move downwards in the region of a working gap A 1 A ', so that the material fed in above the crushing rolls is moved from top to bottom through the working gap A, A 1 .
- the breaking or cutting teeth move upwards so that larger material arriving from above is normally stopped or transported to the next working gap A, A 1 .
- the gap width I, I 1 in the region of an empty gap L, L 1 can be chosen so small that the crushing or cutting teeth 4 can be moved past each other with the shortest possible distance.
- the gap widths I, I 1 are in any case smaller than or equal to the gap widths a, a 1 .
- the gap width I 1 I ' may have a certain minimum dimension, so that the resulting fine grain can also trickle unhindered through the empty gap L, L 1 .
- the crushing rollers are to be arranged offset from one another in the vertical direction and pushed together in the horizontal direction to achieve the lowest possible overall width B, whereby the required gap widths a, a ', I, I 1 are maintained and the deflection of the material flow in the crusher space is minimized becomes.
- the respective width required in the horizontal direction in the crusher space decreases considerably.
- the angle ⁇ can be up to 30 ° to the horizontal, while the angle ß up to 90 ° or 75 °, preferably between 30 and 60 ° can be.
- the crushing roller I 1 could also be arranged above the two remaining crushing rollers 1 and 2.
- the middle crushing roller 2 could, for example, in a lower position between the two crushing rollers I 1 1 'lie.
- FIGS. 3 and 4 show preferred embodiments, each with four crushing rollers 1, 2, 1 ', 2 1 , because there is a total of one working gap A and two working gaps A 1 .
- the side walls 12, 13 carry outer crushing teeth 14, which are not present in Fig. 3.
- the multi-roll crusher according to FIG. 6 has five crushing rolls 1, 2, 2 'with two working gaps A and one edge-side working gap A 1 .
- the material above the five crushing rollers can relatively evenly distribute.
- the cascades or step arrangement of the six rollers according to FIG. 7 offers, in particular, the possibility of uniform distribution over the three working gaps A for a somewhat lateral task, wherein machining on the walls 12, 13 is dispensed with.
- FIGS. 9 to 13 two adjacent crushing rollers, which have an empty gap L between them, are combined to form a unit via a rocker 11.
- the rocker 11 preferably contains and supports roller carriers 11, 11 "arranged and mounted on the outside of the housing on the right and on the left ..
- the rotation axes R of the associated crushing rollers are guided through slots in the housing (not shown) is pressed against this stop by the prestressed spring 16.
- This resilient mounting of the assembly has the advantage that when seizure of too hard or non-breakable materials, the rocker is moved about the axis of rotation 15 against the spring 16, so that the two associated working gaps A, A 1 at the same time by substantially the same extent can open automatically. Once the obstacle is eliminated, the rocker 11 is pivoted back to the starting position by means of the spring 16.
