Producing and processing system for silicon metal powder

Abstract

The invention discloses a producing and processing system for silicon metal powder. The producing and processing system comprises a storage device, a conveying device, a crushing system, a sieving system and a dedusting system, wherein the storage device comprises a raw material storage bin and a product storage bin; the conveying device comprises a vibrating feeder and a bucket elevator; the crushing system consists of three-stage crushing devices: a jaw crusher, a coarse grain hammer crusher and a fine grain hammer crusher; primary crushing reduces the damage to a recrusher; materials subjected to secondary crushing are sieved; finished products are timely screened out to avoid secondary crushing of the finished products; oversize materials are subjected to tertiary crushing and then aresieved; the sieving system consists of three-stage sieving devices: a linear coarse screen, a linear fine screen and a circular fine sieve; the finished products are timely screened out; meanwhile, the sieving precision is ensured; and the dedusting system is formed by connecting a pulse dust collector with a cyclone separator, a pipeline and a power supply device. The production system disclosedby the invention combines three-stage crushing with gradual sieving, so that the productivity and the finished product rate are effectively improved.

Description

technical field [0001] The invention relates to a metal silicon preparation system, in particular to a metal silicon powder production and processing system, which belongs to the field of silicon material processing. Background technique [0002] After years of application and development, the special crushing equipment for metal silicon has become increasingly mature. There are also many types of equipment specially designed for metal silicon crushing on the market, including special grinders (main machines) and complete production lines, and the final crushing effect is also greater. difference. Silicon metal has hard and brittle physical properties. If the pulverization process cannot effectively control the fine powder content, the yield will be greatly reduced, causing huge economic losses to users. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a metal silico...
