Abstract

The invention relates to a metal silicon crushing system, which includes a feeding system, a drop pipe, a crushing system, a screening system, a primary crushing system, a secondary crushing system, a particle manufacturing system, a dust removal system and a discharge system. The feeding system It is connected to the upper end of the drop pipe, and the lower end of the drop pipe is connected to the crushing system. There is a screening system under the crushing system, and a primary crushing system is set under the screening system. system, a discharge system is set under the particle manufacturing system, and the dust removal system is connected to the primary crushing system, secondary crushing system and particle manufacturing system. The overall structure of the invention is simple and practical, with low yield, high production efficiency, low energy consumption, low cost, low failure rate and long service life; the small silicon particles produced and discharged are round and beautiful in shape, good in uniformity, and have no violent shock. Beating and crushing, the amount of powder is small, it is not easy to bring in impurities, and there is no problem of dust pollution.

Description

technical field [0001] The invention belongs to the field of metal silicon smelting and manufacturing, and in particular relates to a metal silicon crushing system. Background technique [0002] At present, the processing of industrial silicon blocks into finished small particles can not only increase the added value of industrial silicon products, but also improve the product competitiveness of industrial silicon producers. The existing industrial silicon granulation process is mainly crushed and produced directly by commercially available general crushing equipment (mainly jaw crushers). The main process is bagged silicon blocks→lifting and unloading→jaw crushing→sieving→obtaining finished products silicon particles. The industrial silicon small particles produced by this method have poor particle shape, poor uniformity, large amount of powder, high equipment cost, high energy consumption, high failure rate, time-consuming maintenance, large loss, low yield, low productio...
