This invention relates to a device for grinding various bulk materials. The goal is to increase the grinding efficiency by adjusting the fineness and increasing the grinding uniformity. The dismounter includes a housing 1, in which the rotor 3 and the fixed disk 4 with concentrically mounted rows of pins 5, the hopper 6 and the discharge nozzle are vertically arranged. In the loading hopper, the valve 9 adjacent to the outer side of the disk is mounted with the guide pin 10 vertically. A through-hole 11 is mounted on the bottom of the disk and in the lower part of the disk between adjacent rows of pins. The housing is connected to the loading hopper a separating chamber with a built-in vibration separator 23. The discharge port is made in the form of two conveying channels with plugs converging in the upper part of the separating chamber. Depending on the position of the valve, the source material enters the working chamber to one or another of the pinned rotor rows, is crushed and sent to a vibroseparator, where it is divided into fractions.

The invention relates to devices for grinding various bulk materials and can be applied in animal feed, chemical, construction and other industries.

The purpose of the invention is to increase the grinding efficiency by regulating the fineness and increasing the uniformity of grinding.

In FIG. 1 shows a dismembrator, general view; FIG. 2 is a section AA in FIG. 1; in FIG. 3 - disambiguator, top view.

The dismembrator comprises a housing 1, a rotor 3 and a fixed disk 4 with concentrically arranged rows of pins 5 forming the grinding stages, a loading hopper 6 with a cover 7 and an unloading pipe 8. are vertically arranged inside the second rotary shaft 8. In the loading hopper 6 is installed adjacent to the outside the fixed disk 4 through the cover 7, the shutter 9 with the guide heel 10. In the shutter 9 at the heel 10, a through window 11 is made, and in the fixed disc of the part of the shutter 9 a latch 18 is made. A separation chamber is mounted on the housing 1 and 19 connected to the hopper 6 channel 20. Inside the separation chamber on the support 21 and the spring-loaded rod 22 is mounted vertically Vibroseparator 23 with a removable sieve 24, and under it in the pallet 25 - 26 screw conveyor finished product. The rod 22 is supported from below by a cam 27 mounted on the shaft 2. The discharge pipe is made in the form of two conveying channels 28 and 29 with plugs 30 and 31. extending from opposite sides of the housing 1 and converging in the upper part of the separation chamber 19.

The dismembrator works as follows.

The source material is fed into the loading hopper 6, enters the space between the inner walls of the hopper, the shutter 9 and the guide heel 10 and through the through holes 11 in the shutter, 14 in the cover 7 and 15 in the fixed disk 4 enters the working chamber to the pins 5 of the rotor 3. Passing under the action of centrifugal forces of the grinding stage, the particles of material are destroyed by pins and carried out by the last concentric row into the transporting channel 28, while the channel 29 is plugged. From the transporting channel 28, the crushed material enters the separation chamber 19 to the vibration separator 23 driven by the shaft 2 through the cam 27 and the stem 22 and is divided into coarse and fine fractions on the sieve 24. The fine fraction (finished product) passing through the openings of the sieve enters the pan 25 and is conveyed outward by the screw conveyor 26 outside the separation chamber, and the large comes off the sieve, passes through the channel 20 to the feed hopper 6 and then to grind. To obtain a different grinding fineness, the shutter 9 is fixed in the other position by means of the latch 18 so that the material to be crushed enters the working chamber through windows 11-13 (finer grinding) or windows 11, 16 and 17 (larger). For the same purpose, a sieve with different hole sizes is installed on the vibratory separator 23. When the working planes of the pins 5 are worn, the direction of rotation of the rotor 3 and the position of the plugs 30 and 31 change, the crushed material enters the conveying channel 29.
