Abstract

FIELD: mining industry. SUBSTANCE: disintegrator has housing 1 closed by covers 2 and 3. Circular partition 4 and reflector 5 are mounted in housing. Circular partition divides housing into central chamber 6 in which conducting 7 and conducted 8 working bodies with teeth on face surfaces are disposed and peripheral chamber 9 in which windows 10 for material removal are located and which go into circular hopper 11. Conducting 7 and conducted 8 working bodies are in engagement and form gear drives with face teeth. Channels 12, 13 and 14 are made in circular partition for supplying gaseous or liquid agents into central chamber. Partition edge and reflector are made curvilinear forming smooth channel for ground material removal from central chamber to peripheral one. Bunker 15 with screen for charging the material into disintegrator is mounted on the cover. Device can be used at enterprises for reprocessing metallic and nonmetalliferous minerals. EFFECT: enhanced efficiency of grinding mineral-organic raw material. 2 dwg

Description

 The invention relates to devices for grinding materials, in particular mineral-organic raw materials, and can be used in enterprises for the processing of ore and non-metallic minerals, medicinal plants and other substances.

 Known devices for grinding materials containing oppositely located and rotating relative to each other discs, on the working surfaces of which there are grinding elements in the form of fingers, protrusions (1,2).

 The disadvantage of these devices is the heterogeneity of the size of the crushed material.

 A device for grinding materials (3), selected as a prototype. It contains a grinding chamber, a working body in the form of a disk placed on it on a vertical shaft, grinding elements mounted along concentric circles on the disk, the lid and the base of the chamber, loading and unloading windows.

 The disadvantage of the prototype (3) is the heterogeneity of the particle sizes of the crushed material, which requires subsequent sorting, for example, using sieves.

 The objective of the invention is to increase the uniformity of particle sizes of the crushed material.

 The task is achieved by the fact that in the disintegrator comprising a housing with covers and windows for loading and removing materials, opposed working bodies with teeth on the end surface, one of which is made leading, according to the invention, the disintegrator is equipped with ring reflectors and a partition, in the inner volume of which are located the working bodies that form the gears, and the partition divides the body into the Central and peripheral chambers, and on the inner surface of the partition there are channels for I supplying gaseous or liquid agent into the central chamber.

 In FIG. 1 shows a General view of the disintegrator, and figure 2 a section aa in figure 1.

 The disintegrator consists of a housing 1, closed by covers 2 and 3. An annular partition 4 and a reflector 5 are installed in the housing. An annular partition divides the housing into a central chamber 6, in which a leading 7 and driven 8 working bodies with teeth on the end surfaces and on the peripheral camera 9 are located , in which there are windows 10 for the removal of material and which go into the annular estrus 11. Lead 7 and driven 8 working bodies are engaged and form gears with end teeth.

 In the annular partition, channels 12,13 and 14 are made for supplying a gaseous or liquid agent to the central chamber. The edge of the partition and the reflector are made curved, forming a smooth channel for diverting the crushed material by the flow of agent from the Central chamber to the peripheral chamber.

 A hopper 15 with a shutter 16 is mounted on the lid for loading material into the disintegrator.

 The disintegrator works as follows.

 Rotation from the engine (not shown in FIG. 1) is transmitted to the shaft of the leading working body 7, which is meshed with the driven working bodies 8. The material intended for grinding from the hopper 15 with the shutter 16 enters the central chamber getting into the center of the leading working body . Under the action of centrifugal forces, this material moves from the center to the edge, where it is captured by the teeth of the working bodies rotating in engagement and is crushed between the contacting surfaces.

 The agent flow, passing through the channels 12,13 and 14, enters the central chamber 6, where it captures the particles of crushed material, carries it up and striking the reflector 5, is sent to the peripheral chamber 9, from which it is diverted through the windows 10 and estrus 11 to the separator ground substance from the agent and poured into the hopper (separator and hopper in figure 1 are not shown). The size of the carried particles is determined by the intensity of the vertical component of the agent flow.

Claims (1)

 A disintegrator comprising a housing with covers and windows for loading and discharging material, opposite working bodies with teeth on the end surface, one of which is made leading, characterized in that the disintegrator is equipped with an annular reflector and a partition, in the internal volume of which there are working bodies forming gears, moreover, the partition divides the casing into the central and peripheral chambers, and channels for supplying gaseous or liquid agent are made on the inner surface of the partition and the central chamber.
