. Closest to the claimed technical essence and the achieved result. The tattoo is a material grinding apparatus, comprising a housing, a grinding device made in the form of two shafts with circular knives, an additional grinding device located below it, a loading hopper, a discharge device and a drive 2.

The purpose of the invention is to increase the efficiency of grinding polymer materials and reduce energy intensity;

The goal is achieved by that; that the installation for grinding materials, comprising a housing, a grinding device - 7 § §, made in the form of two shafts with circular knives, an additional grinding unit under the Strovo, a loading hopper, an unloading device and a drive, is different from the known that the additional the chopping device is made in the form of a rotor, on the shaft of which knives are fixed, interacting with the fixed knives of the casing, while this additional chopping device is offset relative to the vertical axis basically on the side vrav -. : ..

.

rotor brushes for a distance equal to two thicknesses of circular knives, moreover, the case of the additional grinding device is made with a vertical groove connector, the rotor shaft is located in the sides of the case, and the shafts of the main and additional grinding devices are made respectively slow and high-speed and connected to the drive through a tooth-10 chat and overrunning clutches.

The invention is illustrated in the drawings, wherein FIG. 1 - projection of the device from the workplace; in FIG. 2 - view A on

. FIG. 1; in FIG. 3 is a section BB in FIG. 1; on the

15 of FIG. 4 is a section bb in FIG. 2.

The device for grinding materials contains a frame 1 with a drive 2 mounted on it, which is connected by means of a V-belt drive 3, a gearbox 4 and

0 toothed clutch 5 s

. a grinding device 6, the shafts of 7 of which are equipped with circular knives 8, and by means of a V-belt drive 9 and an overrunning clutch 1, the drive is connected to an additional 5; an internal grinding device 11, in the housing 12 of which a window 13 for installing movable knives 14 is made, and is installed in the vertical grooved connector 15, with the help of the sidewalls 16, the rotor shaft 17, which is equipped with disks 18 with movable knives 14 fixed to them, which cooperate with fixed knives 19 installed in the housing 12 additionally; . grinding device. At

35 this is an additional grinding device. 11 is shifted relative to the vertical axis of the main direction of rotation

- the rotor for a distance equal to two thicknesses of circular knives 8 ,.

40 The shafts of the main grinding device 6 are low-speed, and the shaft of the additional grinding device is high-speed.

A hopper 20, equipped with a agitator 21 and a sectional shutter, is attached to the grinding device 6 in the upper part of its 45

22, a comb 23 to its lower part, a bracket 24 connected to a jack 25 to its lateral part, a nut with a slot 26 to its rear part, and to an additional grinding device 11 connected to the grinding device by means of hinged bolts 27 and an axis 28, a calibration grating 29 is mounted to its lower part, mounted on the axis 30 and on the steering wheel 31, and a pallet 32 with a visor 33, a slip 34 to its upper part, and a flywheel 35 installed on the opposite end of the rotor shaft 17.

Installation and dismantling of the installation is carried out using a jack 25, which, through the bracket 24, disconnects the grinding device 6 from the additional grinding device 11. During the reverse movement of the jack 25, the opposite effect occurs.

Installation works as follows. zom.

Polymer materials in the form of boxes and other containers enter the hopper 20 through the sectional shutter 22, where they are fed with the aid of a disorientator 21 to the grinding device 6 in the cutting zone between the disk knives 8 mounted on the shafts 7. Next, the crushed parts are passed through the comb 23 and fed to an additional grinding device 11, in which they are guided by movable knives 14 and skliz 34 to fixed knives 19, where they are crushed to the size of the holes of the calibrating grating 29. Next, the crushed particles are transferred to the pan 32 through zyrek 33 and then to a pneumatic transport (not shown). In this case, the shaft 17 of the additional grinding device 11 is connected to the drive 2 by means of an overrunning clutch 10, which

/R

disconnects it from the drive if the motor 2 is switched to reverse, and one of the shafts 7 (leading) is connected to the gearbox 4 of the gear coupling with the barrel-shaped tooth 5, as a result of which some axis misalignment between the low-speed shaft of the gearbox 4 and the (driving) shaft 7 is possible , which is a prerequisite for the assembly and operation of the installation. The clearance between the blade knives 8 is adjusted with nuts with slots 26 mounted on the shafts 7.
