Abstract

The invention relates to a device for grinding bulk material and makes it possible to increase its grinding degree. The device comprises a housing 1 with a chute 2, in which a crushing device is installed, made in the form of a pair of rolls 3 with teeth 4 and discs 5. To increase the degree of grinding of the material, tooth A4 and rolls 3 are mounted alternating. The tooth 4 of one roll 3 is arranged perpendicularly each in relation to the previous one and opposite to that mounted on the other roll 3 and can interact with the grill 6, and the disks 5 of one roll 3 are installed opposite the disks 5 of the other roll 3. Such an arrangement of processing organs causes the sequence of their action on kau material. due to their alternation in length and location at different levels and ensures overlapping of the intersectional space by these bodies at any of their positions during rotation, which prevents slipping of the unprocessed material in the inter-roll space and ensures complete grinding of the material. 2 Il. / 9

The invention relates to a device for grinding bulk material and can be used in the construction of flax, chemical, mining and other industrial sectors.

The purpose of the invention is to increase the degree of grinding.

FIG. 1 shows a grinding device, top view; FIG. 2, section A-A in FIG. one.

A device for grinding material comprises a housing 1 with a chute 2, in which a crushing device is installed, made in the form of a pair of rolls 3 with teeth 4 and discs

5. Teeth 4 and disks 5 are mounted alternating. Teeth 4 of one roll 3 are arranged perpendicularly each with respect to the previous one and opposite to that installed on the other roller 3 and with the possibility of interaction with the sectional grid

6, and the disks 5 of one roll 3 are mounted opposite the disks 5 of the other roll 3.

The rolls rotate from the actuator 7, the counter-rotation of which is carried out by means of a gear pair 8

The device works as follows.

The material in the form of lumps is fed into the housing 1 on the rolls 3. Large lumps with a diameter of 400-450 mm are caught by the teeth 4 and crushed to a diameter of 100-150 mm. The pre-ground teeth 4 material is then captured and tweaked by the disks 5. The ground material :. is removed from the device through the chute 2. During the process of grinding the material, the teeth 4 are simultaneously cleaned from

adhered material when interacting with sectional lattice 6.

Placing the disks of one roll opposite the disks of the other roll and the position of each of the teeth perpendicular to the previous one and opposite to that installed on the other roller overlap the intersectional space with these bodies at any position during rotation, eliminates overdraft material slipping in the roll-over space and ensures complete grinding material. In addition, when installing the disks of one roll opposite the other, the angle of capture of the material is created and its subsequent processing is ensured. The material is pre-crushed to the size necessary for the capture of the disks protruding above the surface of the teeth of both rolls, which increases the degree of grinding of the material.

Claims (1)

Invention Formula A device for grinding materials, comprising a housing with counter grates placed on its inner surface, rolls with teeth mounted with the possibility of counter-rotation, so that, in order to increase the degree of grinding, on both rolls between the teeth discs mounted opposite one another are mounted, and each tooth of one roll is located in the perpendicular direction relative to the next tooth of the other roll. .
