Use: in devices for grinding materials in various sectors of the industry for grinding ore, clinker, slags, grinding grain. Summary of the invention: one of the disintegrator discs is provided with a rim 4 located along its periphery, and plates 6 interacting with the rim are mounted on the sleeves 5 of the opposite disc. Plates can be made sickle-shaped and have prigruzhi 9. 1 Cp f-crystals, 3 ill.

Description

hO

The invention relates to a device for grinding, can be applied in the construction, mining, chemical and other sectors of the industry and is a further improvement of the invention according to the author. No. 1711971.

The main author's testimony describes a disintegrator, which includes two disks arranged parallel and coaxially to each other, rfa of which are fixed by cantilever fingers in concentric rows, and each row of fingers of one disc is located between two rows of fingers of another disc, and two drives for rotating each disc in opposite sides, with the disintegrator equipped with bushings that are loosely mounted on the fingers.

The disadvantage of the disintegrator is the low grinding efficiency.

The purpose of the invention is to increase the grinding efficiency.

This goal is achieved by the fact that one of the disintegrator disks according to auth.st. No. 1711971 is equipped with a rim located on its periphery, and plates are mounted on the sleeves of the opposite disk with the possibility of interaction with the rim, while the plates can be equipped with weights and crescent-shaped.

FIG. 1 shows a disintegrator; in FIG. 2, a fragment of an interdisk space; in fig. 3 is a cross-section of the peripheral part of the disks

The disintegrator consists of a casing 1 in which two disks 2 are coaxially and parallel to each other. There are fingers 3 on disks in a console-concentric row. One disk 2 is equipped with a rim 4. On fingers 3 of another disk adjacent to a rim 4, put on sleeves 5, which can be connected (welded) with plates 6, the width of which does not exceed the width of the rim 4. The casing 1 is provided with loading

The main cone 7, and the disks 2 are connected to the engines 8.

Works disintegrator as follows.

Engines 8 are turned on, and the disks 2 begin to rotate in opposite directions. In the cone 7 serves crushed material, which falls under the influence of the fingers 3 and, grinding, goes to the periphery of the disks 2. Here, a sufficiently crushed material falls into the space between the plates 6 and the inner surface of the rim 4 of the disk 2. So the sleeves 5 are worn loosely on the fingers 3 then, due to inertial forces, the ends of the plates 6 are pressed against the surface of the rim 4, which provides for an intensive abrasion of the material between them. To enhance the abrasion of the material, the plate 6 can be provided with a preload 9 in the form of additional metal plates. Considering that the relative speed of the surfaces of the rim 4 and the plates 6 can be 300 m / s and above, a thin and superfine abrasion of the material is carried out.

The diameter of the sleeves 5 can be chosen so as to ensure their interaction with the inner surface of the rim 4. In this case, the cylindrical surface of the rim 4 partially rolls over the cylindrical surface of the sleeve 5.
