the cylinder is upright downward required pressure, whereby the ring 111 is pulled downwards.

The ring 111 (Figures 1 and 4) stands with the breaker pin support 41 in support connection via rings 129 made of non-metallic Bearing material which are fitted into recesses in the inner circumference of the ring 111, and over a Ring 131 made of non-metallic] bearing material, which is in the Outer edge of the crushing fuselage support 41 fitted into a recess is. Die.Lagerringe can consist of "Micarta". The ring 131 is of sufficient thickness to allow a margin 159 (Figure 4) between the top of the crushing fuselage support 41 and the bottom of the ring 111 to create. A ring element 165 (FIG. 1) made of the aforementioned non-metallic bearing material is located between the crushing body 49 and the crushing torso support 4I is provided.

Under normal crushing conditions, the top of the rock crusher assembly including the crusher hull support moves 41 and all associated parts do not, while the crushing cone 13 executes gyroscopic movements. However, if unbreakable Objects passing through the rock breaker or when the rock breaker is not operating properly the upper part of the arrangement can be lifted off the support ring 33 at the highest point of the cam 17 against the resistance of the cylinder 121. By this lifting, the breaker trunk support 41 is forced to move relative to the Support ring 33 move slowly.

With other types of cone crushers, attempts are generally made to to prevent this "wandering" by positive locking. The "wandering" causing force can, however, be so great that heavy cast steel pieces and. Holding parts burst. With the inventive described here

JII 3089 - 10 -

Arrangement, if necessary, "wandering" may occur as the refractive trunk support 41 is below the ring 111 can slide and wander around the ring 33, depending on the forces involved. The non-metallic rings 129 and 131 ensure that no wear occurs because metal does not slide along metal.

A machined surface 150 of the shell 91 (Figure 1) is fixed against the main body of the Breeh cone tensioned by means of a self-tightening tensioning element 152 which is screwed into a threaded bushing 154 which is attached to the Breaking cone 13 is fastened by means of head screws 156. One frustoconical cap 158 is by means of a screw and a threaded plug 162 attached to the clamping element 152. A disk-like wedge ring 166 is used by the Element 152 pressed against jacket 91. A frustoconical one disk-like projection 168 is pinned to the top of the main body of the crushing cone 13. Of the Projection 168 has a rectangular opening for receiving a special tool with which element 152 is rotated when the jacket 91 is replaced.

In operation, the material to be shredded enters the top Opening 133 and then moving into the opening 85 of the crushing chamber. As the material moves down between the liner 51 and the jacket 91, it will smashed several times. Sorting takes place in accordance with the position of the closest to the feed 51 Mantle 91. This gap only changes when adjustment is made or when wear occurs. Adjustment can be effected by operating mechanism 90 (Figures 6 and 12) which are three different Has operating modes. One mode of operation is complete

• manually without the support of hydraulic auxiliary cylinders (This operating mode is used if the hydraulic system fails). The second mode of operation is hydraulic actuation, the arm 116 by hand -with a small force is applied. The third loading

drive mode consists in electrical control, namely either on the guest intruder himself or from one of them. Remote control station off.

The operator is responsible for the exclusively manual operation hydraulic pressure to the piston 78, as a result of which the wedges 63 are raised and the crushing body 49 is released will. The lever 124 is inserted into the arm 116 and the operator slides the pawl 93 by hand backwards and forwards, rotating the crushing hull assembly using manual force. After getting a After the crushing chamber of the desired size has been obtained, the wedges 63 are again pressed downwards, so that the crushing body is locked in its position.

In the second mode of operation, the pistons 78 are pressurized to release the crushing body. The operator manually adjusts the pawl 93 so that the crusher body is rotatable in the desired direction. The operator then moves the handle 126 back and forth to operate the valves 120, the Supply the cylinder 109 with fluid so that it causes the pawl 93 to reciprocate. The operator can reverse the setting of the pawl 93 if the operator goes beyond the desired crusher hull height. After the adjustment has been achieved, the pistons 78 are pressed down and lock the crusher body in its position.
