Silicon metal belongs to high hardness materials, brittle and fragile,it will be wear serious to the parts of the mill. In its grinding process, there will often be over-grinding site lead to sieve residue content of the product exceeded. In the actual production of silica fume, the control of sieve residue will be directly related to the company’s competitiveness in the industry. 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 can not effectively control the sieve residue, their product quality is not stable enough, the failure rate is higher and more working hours consumption of maintenance.

According to the characteristics of difficult for grinding of the fragile silicon metal,Guikuang developed a professional silicon metal powder grinding equipment- GK series vertical mill. GK vertical mill 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. It can be widely used in cement, power, metallurgy, chemical industry, non-metallic mineral industries, especially for variety of ore’s milling process. The massive, granular and powdered raw materials can be processed to required pulverized materials.It has a significant advantage in silicon metal grinding process.
