Description

The invention relates to the technique of crushing solid materials for the conditions of hydraulic mines.

For crushing solid materials, gear grinders of the type DZSh, hammer type DMSh, cone type DKMK and rotary are used.

The most reliable and suitable for the conditions of hydraulic mines is a hammer mill.

However, in such crushers, used on hydromines and in coal lining, coal is significantly overmilled, which sharply worsens its grade.

The purpose of the invention is to obtain the possibility of classifying a solid material before durbation (dehydration and its dehydration).

This is achieved by installing a high-tech slurry feed device mounted above the rotor tangentially to the inner surface of the sifter, and the rotor and sieve are installed with an annular gap between them of variable cross-section, decreasing them from top to bottom vertically.

FIG. 1 shows the estimated hammer crusher, vertical section; in fig. 2 shows a section through AA of FIG. one; on fit. 3 and FIG. 4 - hammer crusher in working condition.

Hammer crusher consists of

Vision centrifugal water separator -classifier /, made in the form of a truncated cone with openings commensurate to the class of material being separated, a vertically located rotating rotor 2 with pliers hinged on hammers 3, two tangentially located inlet ports 4 and 5 for the slurry working with working masters, working with a hammer 3, two tangentially arranged inlet ports 4 and 5 for the hydraulic mixture, working for the slurry working with the hammers 3, two hammers 3 and housing 6.

10 Dilotkov crusher works as follows. The slurry, which is transsureted at a certain speed along the chute, is introduced into the centrifugal water separator-classifier: tangentially and the surface through one of the 5 windows (the second window is closed).

Getting into a curved perforated surface and moving along a helical trajectory, the slurry is affected by centrifugal forces and under their action. 1 is pressed against the perforated casing of the centrifugal water separator-classifier /, and a fine class of material with water is separated from the crushing zone through the hole.

A coarse material that does not pass through the 5th classifier, moving from top to bottom on a helical path, encounters rapidly rotating hammers and collapses.

The destruction of the material does not occur on

breaker plate or grate, and

0 on the fly, i.e. the so-called
