Epoxy molding compound is composed of epoxy resin, curing agent and silica powder, etc. after processing, Epoxy molding compound filler used in all crystalline silica dioxide, its performance characteristics are high thermal conductivity, the linear expansion coefficient is large, and low cost. Silica is refined from silicon metal milling. 

Silicon metal is also called crystalline silicon or industrial silicon, which is composed of quartz and coke in an electric smelting furnace. In order to improve the metal silicon active in the application process, you need to grind silicon metal block to a certain fineness, the current domestic and international markets required fineness standard of silica fume control in general 500-1μm (30-12500 mesh), in which (500-80μm) 30-180 mesh silica fume has high demand, the market prospects are better. The fineness of 45μm or less of silica sand fume has low price, which means grinding mill and classifier are put forward higher requirements. 

Silicon metal belongs to high hardness materials, brittle and fragile, it will be wear serious to the parts of the mill. So high yield and quality must choose wear and stable equipment from the good reputation of the manufacturer, this will not only lead to higher efficiency, more importantly, when the device fails, the good manufacturer will provide after-sales service, eliminating the customer's worries. At present, the application of more silicon powder production equipment is raymond mill and roller-crushing mill, these two devices have the problems of high efficiency and low energy consumption and cannot effectively control the sieve residue, their product quality is not stable enough, the failure rate is higher and more working hours consumption of maintenance. 

SMPCRUSHER is a professional manufacturer of crushing and mill equipment, VM vertical mill of it uses reasonable and reliable structural design, with advanced technological process, set the crushing, drying, grinding, separating, lifting in one. It is very suitable for large-scale grinding process, the main technical and economic indicators have reached the international advanced level, especially for variety of ore's milling. The massive, granular and powdered raw materials can be processed to required pulverized materials. It has a significant advantage in silicon metal grinding process.
