Plate bumping type processing method and device for metal silicon powder

Abstract

The invention discloses a plate bumping type processing method and device for metal silicon powder. An abrasion-resistant impact plate is arranged in the middle of a cylindrical crushing cavity, and an inner cavity of the cylindrical crushing cavity is in communication with an impeller shell of a material throwing mechanism. In addition, the outlet of the impeller shell corresponds to the abrasion-resistant impact plate, the inlet of the impeller shell is in communication with a feeding port, and materials fall to the center of an impeller of the material throwing mechanism through the feedingport. The impeller rotating at a high speed instantaneously throws the materials onto the abrasion-resistant impact plate to realize efficient crushing of the materials, and different crushing effects are realized by adjusting parameters such as the rotating speed of the impeller, the distance between the abrasion-resistant impact plate and the material throwing mechanism, and the air volume of afan. Openings are formed in the upper part and the lower part of the cylindrical crushing cavity, and the crushed materials are pulled up through a cone-shaped body on the upper half part of the crushing cavity under the action of induced air power of the fan at the upper opening. According to the plate bumping type processing method and device for the metal silicon powder, the different crushingeffects can be realized by adjusting the parameters such as the rotating speed of the impeller, the distance between the abrasion-resistant plate and the material throwing mechanism and the air volume of the fan.

Description

Technical field: [0001] The invention relates to a method for processing silicon powder, in particular to a method and device for processing metal silicon powder of a striking plate type. Background technique: [0002] Industrial silicon powder, also known as metal silicon powder, is silver gray or dark gray powder with metallic luster. It has high melting point, good heat resistance, high electrical resistivity, and high anti-oxidation effect. It is called "industrial monosodium glutamate" and is an indispensable basic raw material for many high-tech industries. At present, there are many types of metal silicon powder making equipment, but because metal silicon is a hard and brittle material, it is difficult to control the total amount of fine powder in the pulverization process, and the requirements for the wear-resistant materials of the pulverizer are relatively high. If the above two If the difficulties are effectively solved, various problems will arise in the product...

Problems solved by technology

At present, there are many types of metal silicon powder making equipment, but because metal silicon is a hard and brittle material, it is difficult to control the total amount of fine powder in the pulverization process, and the requirements for the wear-resistant materials of the pulverizer are relatively high. If the above two Difficulties are effectively solved, and various problems will appear in the production process. Not only the equipment cannot produce qualified products, but also it will cause a great waste of resources.
