Mine material sorting device

Abstract

The invention relates to the technical field of mine equipment, and provides a mine material sorting device which comprises a shell and a screen drum which is erected in the shell and has rotational freedom, a blanking cavity is formed between the screen drum and the shell, and a blanking port is formed in the bottom of the shell. All the separation rings are arranged in the axial direction of the screen drums, the blanking cavity is divided into at least three separation cavities through the separation rings, the apertures of screen holes of the screen drums located in the same separation cavity are equal, the apertures of the screen holes of the screen drums are gradually increased from the feeding port ends of the screen drums to the discharging port ends of the screen drums, and blanking ports are formed in the positions, corresponding to the separation cavities, of the bottom of the shell. The problems that in the prior art, due to the fact that the diameter of screen holes of a sorting device is fixed, only one-time sorting can be achieved, finer sorting cannot be achieved for large-particle materials which cannot pass through the screen holes, and the sorting requirement cannot be better met are solved.

Description

technical field [0001] The invention relates to the technical field of mining equipment, in particular to a mine material sorting device. Background technique [0002] The sorting device is an important equipment in the mining industry. The current sorting device is equipped with a screen cylinder in the shell, the discharge port of the screen cylinder is inclined downward, and the bottom of the shell is provided with a discharge port, and the material flows from the screen cylinder. The feeding port is fed. During the rotation of the sieve drum, the small particles of materials fall through the sieve holes on the side wall of the sieve drum, and then are discharged through the discharge port, while the large particles of materials cannot pass through the sieve holes and are discharged from the sieve drum. the other end of the discharge. This kind of sorting device has a certain sieve hole diameter and can only achieve one-time sorting. For the large particle materials that...
