Description

(5) DEVICE FOR CUTTING MATERIALS

t

The invention relates to a device for grinding materials and can be used in the construction, mining and other industries.

Closest to the present invention is a device comprising a housing, a guide device, opposite which flip plate fl 3 is installed.

A disadvantage of this device is the impossibility of carrying out the screening and the return of the uncrushed material to the ground.

The purpose of the invention is to improve the grinding efficiency. This goal is achieved by the fact that a device for grinding materials, including a housing that guides n (the station opposite to which the plate is installed, is equipped with a lift, made in the form of a series of vertically spaced with a gap:

shelves, and wallpaper plate. is located inside the lift.

In addition, in the upper part of the body above the lift, fingers are fixedly mounted.

Phi, 1 depicts a grinding unit, general view; in FIG. 2, view A in FIG. one.

The mother chopping device, Q Alov, includes a housing 1, a guiding device consisting of pneumatic rotors 2 and 3 mounted rotatably on opposite sides, receiving

, 5 bunker And, device 5 for tensioning the drive chain (belt) node 7 for adjusting the distance, between the rotors 2 and 3, the electric motor 8, the baffle plate 9, the lift,

Claims (2)

20 made in the form of a series of vertically arranged with a gap of rings 10 and 11, having transverse flanges 12, supporting roller 13, driving datak 1, electric motor 15, reflective screen 16 with horizontal slit 17 for material to pass to the crushing zone, tray 18 return material, to be subject to the looser), output tray, 19, fingers 20 for cleaning the slots 21 of the elevator, supporting plate 22 for preventing - premature fall of the material lifted by the elevator. The material is supplied to the device by a conveyor 23, and from water, a crushed product, by a conveyor 2k. The device works as follows. The crushable material is guided by a conveyor 23 and a tray and the zone between the rotors 2 W 3, where it comes into elastic contact with them and, thrown out on the other hand, strikes the breaker plate 9 into separate pieces that step onto the lift . Pieces that have been crushed to the required size fall down, and those that require additional crushing — by means of transverse shelves 12 and tray 18 — enter the storage bin of the same crusher. Thus, a closed cycle is organized directly inside the crusher. When lifting material, it is necessary to distinguish two stages. Approximately up to half the height of the lift, the supporting surfaces of the middle material are the transverse flanges 12 and the screening surface between them. Above, the material rests on the transverse shelves 12 and on the support plate 22 (in the absence of the plate 22, material lifting is possible only up to the middle of the height of the elevator). The finger 20 enters the classifying slot 21 of the elevator in such a way that during the rotation of the elevator there is no engagement with the shelves 12. At the same time, pieces that have not passed through the slot and trapped in it are pushed down by the finger 20, fall into the tray 18 and again fall into the receiving bunker k. The use of the proposed device makes it possible to increase the grinding efficiency. Claim 1. A device for grinding materials, including a housing, a guide device, opposite which a fender plate is installed, characterized in that, in order to increase the grinding efficiency, the device is equipped with a lift, made in the form of a series of vertically spaced rings with transverse shelves, and the plate is located inside the lift. 2. The device according to claim 1, characterized in that, in order to enable the cleaning of the lift, in the upper part of the body above the lift, the fingers are fixed.
