When large, non-crushed pieces fall, hammers are able to move in elongated holes. A disadvantage of the known crusher is that during operation, the cells are worn out, and when large, non-crushed pieces of the source material get damaged. The destruction of the hammers occurs due to the hard impact of a large piece of non-crushed material, since the axes of the hammers can move 25 disks elongated along the radius in the holes.

Claims

SUMMARY OF THE INVENTION 1 CRUSHER, comprising parallel to but 55 fixed disks on the shaft with holes on their periphery, working bodies with axes freely placed in the holes of adjacent disks, characterized in that, with an efficiency chain

in the holes 5 to the edge of the disks 4, while the axes 7 occupy a position of minimal distance from the edge of the disks 4 (Fig. 1).

When the feed material is fed into the crusher, the pieces are first impacted by the rollers 6 and partially crushed. Then, the pieces of the raw material fall onto the grate 2, on which they are crushed by the rollers 6.

In this case, the rollers b rotate on the axes 7 and are rolled through pieces of the starting material, which excludes crushing by abrasion, and the wear of the rollers is prevented. Due to the fact that the starting material has a certain strength, the rollers, interacting with its pieces on the grate, occupy some intermediate position in the holes 5 (Fig. 2).

When a large, non-crushed Piece, which is shaded in Fig. 3, gets into the crusher, the rollers 6, interacting with it on the grill 2, are maximally recessed into the disks 4. The rollers are rolled through the non-fragment, which is removed from the crushing zone. In this way, the destruction of the rollers is prevented when crushed pieces fall into the crusher. Figure 4 shows that the diameter of the hole exceeds the diameter of the axis 11, the sum of the radius of the roller R and the radius of its axis g must be greater than the sum of the diameter of the hole d and the distance from the hole to the edge of the disk h. If this condition is not fulfilled, the edges of the disks will wear out with the initial material in the presence of large cedible pieces in it.

The boundary between the radius of the roller R and the radius of its axis r must be less than the distance from the hole to the shaft of the disk N. Otherwise, the roller at the maximum distance from the edge of the disk will touch the disk shaft. To reduce the rotation resistance of the rollers in the round holes of the disks, when rolling them through the material on the grate, the axles can be freely mounted on the rollers. This reduces wear on the inner surface of the holes.

The use of a crusher will increase the efficiency of crushing.
