    A device for the homogenization of material to be crushed particularly for crushing coal to uniform grain size comprises a first conveyor for feeding the material to be crushed which has an upper section and a lower section which extends downwardly away from and below the upper section. A coarse material conveyor overlies the lower section and is disposed at the level of the upper section and between it and the upper section there is a grading device which permits deflection of the fine material so that it is fed downwardly with the lower section and the transfer of the coarse material over the lower section onto a perforated crusher plate. A crushing roll is disposed above the crusher plate in a position to crush the coarse material which is fed thereon to a side operable to the material carried by the lower section and to deposit this material onto the lower section by passage through the openings of the crusher plate.

    Fig, 1 schematically shows the proposed device, side view. in fig. 2 - the same, top view; in fig. 3 shows section A-A in FIG. one.
    A device for crushing material 1, 5, in particular coal, mainly to a uniform grain size has a crushing roll 2 for crushing coarse crushing material 3 with rolls 4 located at a predetermined height above the Slab 5 of rolls 4. In addition, the conveyor 6 retracts the subject crushing material 1 and is directed almost to the level of crushing gasche 5, then deviates downwards and is directed further under the crushing board 5. In the section of the conveyor belt 6 between it and the crushing plate, there is a classifier 7- for the separator of the subject the grinding of coarse material 3 from fine material 8. Above a 20 bbl pry1toy 5, a conveyor 9 passing under a crushing roller 4, to receive and further transport the coarse material 3 crushed through a crushing roller 4, we will take transport 25 grain size of fine material 8 croup 1 material 3 behind a crushing roll 2 fm koyer 6 And thus crushed coarse material 3 delivers-30 s again with a corresponding grain size transported by conveyor 6 to fines 8. Conveyor 6 is made in the form of a chain scraper conveyor, and according to an example of execution in 35 as a double chain conveyor, the classifier is made in a vvde plate 7 to divert the crushed coarse material 3 from the crusher material 1 withdrawn and to transfer the accumulated coarse material to a vehicle 8 on the crushing slab 5. In addition, the Kpovte slab 7 is wedge-shaped, extending downward in the direction of the transport to the crushing slab 5. The bottom 45 side of the slab serves as the top guide 10 for the branch 11 chains of leads 12 binary chain conveyors.
    In addition, the plate 7 has a scraper. elements 13, while drivers of a 12-chain scraper conveyor have corresponding recesses 14, so that the crushing material 1 is subject to a large amount of material 3 to be deep enough to dislodge the crushing material 3. Medical equipment 7 and vehicle 9 pre. there is a heated gap 15, which is open to the coveyor 6 underneath and allows the supply of a small material 8 randomly trapped with coarse material 3 onto the plate, 7 of the fine material 8 in front of the entrance. to the roller crusher 2 on the conveyor 6. The crushing plate 5 is made in the form of a screening plate with holes of a given size so that the fine material 8 obtained during grinding passes through the crushing plate 5 to the conveyor 6 directed under it to the grinding machine. in the form of a scraper belt with flat, scrapers 16 and its own drive unit 17 surrounding the crushing plate 5. The vehicle drive unit 17 has an overload safety device dependent on the number of revolutions Working in zavisgouyusti of dowry muller
    4 speed rotation controllers. When the crushing roll is overloaded through the rotation speed regulator, it is possible to turn off the drive unit 17 of the vehicle 9. If the crushing roll speed increases again, then again drive. dits into action the vehicle 9. Conveyor 9, classifier 7 and crushing roll 2 with a crushing plate
    5 and a vehicle rotating around it. means 9 are located (in the zone of the crushing device) in subdivided according to the cube structure of the casing 1 8, so that during assembly
    And the repair work can be partially removed.
