The difference between grinding silicon dioxide and silicon carbide

Often there are customers who consult the mill, there are processing silicon carbide, there are processing silicon dioxide, but it is not that what materials can be processed with a kind of equipment, it is to be decided according to its nature.

The difference between the two grinding, lies in the hardness there is a difference in physical properties, silicon carbide is quartz, petroleum coke and other raw materials after high temperature smelting, hexagonal crystals, hardness. Silicon dioxide mainly exists in silica, quartzite, diatomaceous earth and other natural materials, relatively low hardness.

If you look at the wear and tear from the grinding equipment, processing silicon carbide on the material requirements of the equipment wear parts are higher, half of the wear-resistant material can not withstand a long time grinding, so the use of ball mills will be relatively good, the ball wear fast, it is constantly adding balls, in order to be able to achieve a higher fineness, in order to achieve a higher fineness, it is in the milling system using the selective classifier will be separated from the fines, up to the fineness of return to ball mills to re-grind.

If the output and price cost-effective, the use of high-pressure grinding mill processing silica better, the same output and fineness, processing of silicon carbide ball milling system than the high-pressure grinding mill the price of the whole set of equipment is twice as high. After years of research experiments, some customers in the processing of quartz powder, silicon dioxide and other materials, the use of high-pressure mill effect is very good.
