Description

The invention relates to the technique of ultrafine grinding of materials and can be used in the fields that require grinding materials to micron particles and the selection of these fractions, for example, chemical, building, food.

A device for grinding materials is known, comprising a housing filled with grinding bodies, loading and unloading pipes, drive G. The disadvantage of this device is the impossibility of selectively selecting fractions,

The closest technical solution known to the invention is a device for grinding material, comprising a housing filled with grinding bodies, mounted in the bottom of the housing. A disk with a relief working surface, drive 2. The disadvantage of this device is that the crushed particles reach micron sizes, it is impossible to extract from the working chamber, since they form a floating cloud in it and gradually settle on the inner surface of the chamber,

The invention aims at the continuous selective selection of fine-faction fractions.

This goal is achieved by tem | that a device for grinding material, comprising a housing filled with transfusing bodies, an actuator mounted on the bottom of the housing with a raised working surface, an actuator, is provided with a perforated cover located in the upper part of the housing, a collection of the finished product sealed to the lid and reflectors fixed on inner surface of the housing.

The drawing shows the device in. the cut.

The grinding device comprises a housing 1 with grinding bodies 2, mounted in the bottom of the housing and rotating from a drive (not shown) disk 3 with a relief working surface, a perforated cover 4 mounted in the upper part of the housing, a collection 5 of the finished product, reflectors 6, reinforced on the inner surface of the case, loading hopper 7, gas blower 8,. The device works as follows. The grinded material from the feed hopper 7 is fed to the winch, and the drive is connected to the 3 n drive. At the same time, the grinding bodies 2 and the material, colliding with the rotating disk and the reflectors 6, transfer to the floating (chaotic) state, intensively grinding the material. Material reaching micron sizes forms a cloud in the treatment chamber and rises to the chip 4. Particles smaller than the diameter of the lid openings pass through the perforations and enter the collection Oi Larger individuals. fall back into the processing chamber. At the same time, the clogging of the material was eliminated because the grinding bodies, constantly striking the lid, pushed it into a vibrating state. If desired, a gas-blowing device 8 is switched on the steep fractions, the gas flow of which keeps parts of the material of a certain fraction in a suspended state and directs the caps to the airframe along the direction of the gas flow exit.
