V-shaped powder selecting machine

Abstract

The invention discloses a V-shaped powder selecting machine and relates to the technical field of material powder selecting equipment. A powder homogenizer is added into a feeder of the V-shaped powder selecting machine, and the powder homogenizer enables materials to be diffused, distributed, pre-dispersed and rectified through a flow spreading layer, a material distributing layer and a rectifying layer arranged on a feeding surface of the powder homogenizer, so that a material curtain with coarse and fine powder uniformly distributed is formed in the width direction of the powder selecting surface of the V-shaped powder selecting machine; air flow formed by the powder homogenizer penetrates through the feeding surface and penetrates through the material distributing layer and the rectifying layer, so that material accumulation is prevented; and a magnetic roller is arranged in the feeder, and iron foreign matters mixed in the materials are removed through the magnetic attraction effect of the magnetic roller.

Description

technical field [0001] The invention relates to the technical field of material powder selecting equipment, in particular to a V-type powder selecting machine. Background technique [0002] With the development of material grinding technology, roller press (high pressure roller mill) has been widely used. The roller press grinding system combined with roller press (high pressure roller mill) and classifier is an efficient The energy-saving grinding system has a very broad application prospect in the mineral grinding production industry. The V-shaped powder classifier that integrates drying, dispersing and grading together with the roller press (high pressure roller mill) has also been greatly developed and widely used. [0003] The process flow of the roller press grinding system combined with the roller press (high pressure roller mill) and the powder classifier is usually as follows: the material after the roller press enters the V-type classifier to classify the powder, ...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the fine powder and coarse powder of the existing powder classifier cannot be fully separated, resulting in over-grinding of the fine powder, and the problem that the existing powder classifier cannot separate the iron parts, resulting in serious damage to the roller surface of the roller press. The invention provides a V-type powder separator. By adding a powder homogenizer to the feeder of the V-type powder separator, the powder is expanded, pre-dispersed and rectified, so that the V-type powder separator A curtain of coarse and fine powder is evenly distributed in the width direction of the powder selection surface, and a magnetic roller is installed in the feeder, and the iron foreign matter mixed in the material is removed through the magnetic attraction of the magnetic roller
