a grinding equipment

Abstract

The invention provides a grinding equipment, comprising: a feeding system connected to the inlet of the casing grinding chamber; a casing grinding chamber and an impeller rotor for grinding; an ultra-high-speed variable frequency motor driving the impeller rotor; The outlet flange at the outlet of the casing grinding chamber can obtain powders of different particle sizes by adjusting the inner diameter of the throttle nozzle of the outlet flange; the receiving system connected to the outlet flange; the air induction system connected to the receiving system. In the present invention, the material, the high-speed impeller rotor and the particles collide, collide, rub, shear, and squeeze each other at ultra-high speed and ultra-high frequency, and assist the ultra-high-speed, ultra-high-frequency mechanical collision between the hammer head and the particles, so as to realize the impact on the material. The advanced micro-nano ultra-fine grinding improves the grinding efficiency and reduces the energy consumption and noise of the equipment. At the same time, according to different particle size requirements, flanges with different inner diameters are used to obtain powders of different particle sizes without a special classification system, which reduces equipment costs and operating costs, and improves grinding efficiency and grinding fineness.

Description

technical field [0001] The invention relates to the field of material processing, in particular to a mechanical airflow mixing and grinding equipment for processing micro-nano ultra-fine powder and nanometer materials. Background technique [0002] Ultrafine pulverization is a high-tech developed rapidly in recent decades. It can process raw materials into micron or even nanometer ultrafine powder. With the rapid development of science and technology, the research and application of micronano ultrafine powder and nanomaterials, It plays an extremely important role in promoting industrial technological progress. After the material is refined, many new excellent properties often appear. Due to the ultra-fine powder particle size, large specific surface area, uniform distribution, and few defects, it has high surface activity, fast chemical reaction speed, high solubility, low sintering temperature, high sintered body strength, and good filling and reinforcing properties. It ...
