Description

The invention relates to a device for grinding and can be used in the food, chemical and other sectors of the industry.

The purpose of the invention is to increase the efficiency of the grinding process of wet materials.

FIG. 1 shows a general view of a device for grinding materials; in fig. 2 is a section A-A in FIG. I.

A device for grinding materials includes a housing 1, a fixed knife 2, a rotor 3 with knives 4, located on a vertical shaft 5, a hopper 6, a loading 7 and a discharge 8 branch pipes, a discharge device 9 with cutters 10, ring elements 11, a bottom 12, a flexible shell 13, which covers the fixed 2 and the bottom of the NII movable knives 14.

A device for grinding materials operates as follows.

The material from the hopper 6 through the loading nozzle 7 enters the ring elements 11.,

Moving knives V4 of the rotor when rotating the shaft 5 alternately enter the gap between the ring elements 11 cut and throw on the stationary knife 2 material, the dimensions of which ensure its passage through the cutter 2, the Discharge device 9 distributes the material on the stationary knife 2 " of the device, a part of the cut material with movable knives 14 the mouth of an oracle is thrown onto the surface of the housing 1. The cutters 10 cut the material off the surface of the housing J and feed it onto the stationary knife 2.

From the fixed blade 2, the material enters the gap between the fixed blade 2 and the rotor.3, where the knives 4 carry out the grinding of the material to a predetermined size. The crushed material enters the discharge port 8. A part of its rotating rotor 3 is thrown onto a flexible shell 13, which vibrates and self-cleans under the action of the material falling on its material.

A device for grinding materials has been developed to meet the requirements of the process of isolating wet materials.

The difficulty in grinding these TepHajjoB is that they

do not allow repeated exposure to cutting elements. As a result of repeated exposure, the wet material liquefies, sticks to the internal surfaces of the device, knives, rotor. Therefore, one of the main grinding conditions is to minimize the impact of the cutting elements on the material being ground.

This is achieved by material from the gaps between the annular elements, the bottom and the loading nozzle immediately after shearing and feeding it into the gap between the fixed knife and the rotor.

Claims (2)

1. A device for grinding materials, comprising a housing, on the inner surface of which, in its lower part there is a fixed knife, a rotor with hammers, located on a vertical shaft, a loading and unloading nozzles, and an unloading device, characterized in that In terms of the efficiency of the grinding process of wet materials, the casing is provided with annular elements arranged with a gap one above the other coaxially of the bunker and the bottom mounted under them, with the movable rotor blades located in the back between the annular elements, and the discharge device has cutters, while in the discharge nozzle a shell is fixed coaxially and flexible. The fixed and lower movable blades are flexible around the outer diameter. 2. A shredder according to claim 1, wherein the annular elements in cross section are a cone that faces a discharging nozzle with a large base. Faye. 2
