Abstract

The invention relates to mills for grinding materials prone to sticking, and may be: ..use- Vano, for example, in the building materials industry. The aim of the invention is to improve the reliability of the mill. For this, the drum is dialed out. rings 5, fastened with rods 6 with gaps, which include cleaning devices, the latter can be made in the form of rings 9 placed inside or outside the drum, combs or hammer shafts. As a result, clearances between the rings 5 are cleaned and material sticking is prevented. 3 hp f-ly, 3 ill.

The invention relates to the technique of grinding materials and can be used in the mining, chemical and other areas of bulk.

The purpose of the invention is to increase the reliability of the mill.

Figure 1 shows a mill for grinding viscous materials with internal drum mount, longitudinal section; figure 2 - the same, with external fastening of the rings of the drum; on fig.Z - the same, with internal fastening of the rings of the drum and the external cleaning comb.

The pre-grinding mill i has a discharge grid 2 with a discharge cone 3 and elevators 4. On the discharge side, a drum is attached to the mill 1 and consists of mutually arranged rings 5 with each other, which can be connected using power rods 6 or radial rods 7 fixed inside the power shell 8. In the gaps between the rings 5, cleaning rings 9 are freely installed, and when rings 5 are attached to the shell 8, cleaning rings 10 are installed.

Cleaning devices can also be installed in the form of stationary or rotating combs. Beer as a hammer shaft 12 installed inside or outside the rings 5. On the discharge side of the drum formed by the rings 5, a discharge grid 13 or inclined retaining ring 14 can be installed. the drum of the rings 5 is closed by a casing 15 with a discharge chute 16. The mill can be equipped with a roller 17, which is suspended on piping 18 and to the th 19 in the casing 15,

A mill for grinding viscous materials works as follows.

The raw material enters the pre-grinding mill, from where through the grate 2 with the help of lifters 4 through the discharge casing 3 gets inside the drum consisting of rings 5, in which, due to the impact of the grinding bodies, the material is finally crushed.

The crushed product is discharged through the gaps between the rings 5 through the chute 16. At the same time, the gaps are cleaned by moving rings 9 and 10, a toothed comb 1I, which can be rotated, or a hammer shaft 2. In the case of significant viscosity of the material being processed, rings 9 can be pressed from roller 17, suspended on bearings 18 and t gah) 9 inside the casing 15.

Claims (3)

1. A grinding mill for grinding materials, including a rotating drum with cleaning devices, characterized in that, in order to increase the reliability of the mill, the drum is made of rings attached to each other with gaps, which include cleaning devices. 2. A mill according to claim 1, wherein the cleaning devices are located outside the drum. 3. Mill on the PP. I and 2, characterized in that the cleaning devices are made in the form of combs. 1 Compiled by B. Mol Vko Editor I. Casarda Techred.
