Metallic silicon crushing system

Abstract

The invention relates to a metallic silicon crushing system which comprises a feeding system, a dropping pipeline, a crushing system, a screening system, a primary crushing system, a secondary crushing system, a particle producing system, a dust removing system and a discharging system, wherein the feeding system is connected with the upper end of the dropping pipeline; the lower end of the dropping pipeline is connected with the crushing system; the screening system is arranged below the crushing system; the primary crushing system is arranged below the screening system, and is connected with the secondary crushing system; the secondary crushing system is connected with the particle producing system; the discharging system is arranged below the particle producing system; the dust removing system is connected with the primary crushing system, the secondary crushing system and the particle producing system. The metallic silicon crushing system is simple and practical in overall structure, low in yield, high in production efficiency, lower in energy consumption, low in cost, low in failure rate and long in service life; the produced discharged small silicon particles are round and aesthetic in particle shape, good in uniformity, free of violent struck crushing, small in powder amount, low in possibility of impurity introduction, and free of dust pollution problems.

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...
