Abstract

FIELD: grinding equipment for mineral-organic raw material, industrial and consumption wastes. SUBSTANCE: disintegrator has cylindrical milling chamber with covers and windows adapted for charging and discharge of material, and opposite disks with grinding members on their end surfaces. One of disks serves as drive disk. Material charging window is positioned in cover at side adjacent to drive disk, in zone free from it. EFFECT: increased efficiency and wider operational capabilities. 2 dwg

Description

 The invention relates to devices for grinding materials, in particular mineral-organic raw materials, production and consumption waste, and can be used in enterprises for the processing of domestic and industrial waste, especially those containing elastoplastic components of ore and non-metallic minerals, legumes, legumes, and medicinal plants.

 Known devices for grinding materials, including oppositely located and coaxially rotating relative to each other grinding elements located in a cylindrical grinding chamber. Grinding elements are made in the form of knives, fingers, rollers [1, 2, 3].

 The disadvantage of these devices is poor grinding of materials with elastoplastic components.

 The closest analogue is a device for grinding materials, containing a cylindrical grinding chamber with covers and windows for loading and discharging material, located opposite the disks with grinding elements on the end surfaces, one of the disks being made leading and mounted eccentrically relative to the driven disk, and the grinding elements on the disks form a gear transmission, grinding occurs due to compression deformation, shear, partially impact, cutting and abrasion [4].

 The disadvantage of this device is the location of the window for loading in the upper part of the cylindrical grinding chamber above the grinding elements of the driven disk, which overlap the window - this reduces productivity, makes it difficult to access the crushed material into the grinding chamber.

 The objective of the invention is to increase productivity and expand the technological capabilities of the disintegrator when grinding materials with larger sizes.

 The objective is achieved in that in a disintegrator containing a cylindrical grinding chamber with covers and windows for loading and discharging material, opposed disks with grinding elements on the end surfaces, wherein one of the disks is made leading and an eccentrically driven disk is installed, the loading window is made in the lid from the leading disk in the zone free of it.

 In FIG. 1 shows a General view of the disintegrator.

 In FIG. 2 is a section along AA in FIG. 1.

 The disintegrator comprises a cylindrical grinding chamber 1, a drive disk 2, located eccentrically relative to the driven disk 3, which is mounted coaxially with the cylindrical grinding chamber. The grinding elements 4 and 5 on the master and slave disks form an end gear. Disks 2 and 3 are mounted on shafts, mounted supports in covers 6 and 7. In the lower part of the grinding chamber, at the interface of the grinding elements, there is a window 8 for removing material with a grill installed in it. The window 9 for loading material is located in the cover 7 in the area free of the leading disk, this allows you to increase the productivity and size of the crushed material, directing it directly to the grinding chamber, bypassing the rotation zone of the grinding elements on the driven disk.

 The disintegrator works as follows.

 The material intended for grinding, through the window 9 for loading enters the grinding chamber 1, where it is engaged between the grinding elements of the master and driven discs. In meshing, compressive and shear forces act on the material. As a result of this, the disintegrator can also grind brittle and elastoplastic materials. The crushed material is discharged through the holes in the grate installed in the window 8 for the removal of material.
