Abstract

Use: The discharge grill of the drum mill relates to a grinding technique and can be used in industrial construction materials. SUMMARY OF THE INVENTION: The discharge grid is composed of spacer rings separated by spacer rings, which are freely interconnected between each other. The difference is in the implementation of loosely placed one in the other rings fixed from axial movement. 3 il.

Description

The invention relates to a grinding technique and can be used in industrial construction materials.

Known discharge grids drum mills.

The closest in technical essence is a discharge grid of freely installed elements and axial stops.

Such a lattice is easy to manufacture and provides its functions.

A disadvantage of the known lattice is the low throughput due to the lack of self-cleaning.

The aim of the invention is to increase throughput.

This goal is achieved by the fact that in the discharge grid of freely installed elements and axial stops, the elements are made and are freely located one in the other and fixed from axial movement of rings with spacers fixed on them.

Such a lattice has a larger living section due to the fact that the constituent elements may have a smaller section, since are located between the force limiters against axial movement, as well as self-cleaning due to relative rotation of the rings.

Figure 1 presents the proposed device; figure 2 - section aa in figure 1; fig. 3 shows node I in fig. 1 in various versions.

The drum 1 with the tires 2 is rotated by means of a driving gear 3 on the support rollers 4.

Inside the drum 1, between the stops 5, rings 6 are freely positioned with spacers 7, and the rings 6 can be of triangular or circular cross section, as shown in FIG.

Distal thickness. of the dionic gaskets 7 is determined by the size of the particles that must pass through the rack, and their number around the circumference 1 is minimized

No one can bend the rings 6 from the effects of the material and grinding bodies.

The cross section of the stops 5 and the number of their rays around the circumference is determined by the calculation of the bending from the impact of the grinding bodies and the material.

The number of rings b is taken as far as possible due to the condition of excluding their bending from the impact of grinding bodies and material.

The gap between the inner and outer rings b is taken from the condition of ensuring their mobility in each other.

The remaining dimensions are determined constructively and tested for strength and performance.

The lattice works as follows.

When the drum 1 rotates, the ring 6 between the limiters 5 rolls into each other along the gaskets 7, which ensures self-cleaning.

The use of the grid provides greater throughput, which increases productivity, and self-cleaning reduces the downtime for cleaning grids, which increases production.

At wear of rings 6 gaps between them

do not increase, because Gaskets 7 also wear out at the same time, which increases durability and reduces repair costs. When the gaskets 7 are worn, the gaps between the rings B increase only in the upper part, where there is no material and therefore they do not affect the work.
