Quartz powder is also called silica powder. As a type of basic industrial raw material, high-quality quartz powder has wide application in glass, glass fiber, ceramics and refractory, metallurgy, construction, chemistry, casting, grinding material, electron and optical fiber industry.
It is a difficult process to process the quartz to high-quality quartz powder and the main equipment for grinding quartz in domestic market is vertical roller mill and rod mill. When Raymond mill is used, the output is about 1t/h, and the efficiency is low, the energy consumption is high and the production granularity cannot be easily controlled. In addition, the wear-resistant material that Raymond mill uses is high manganese steel which has weak magnetism, so that the mechanical iron cannot be easily removed. When using rod mill, the production indexes are no better than that of Raymond mill. With the increase of powder fineness, the iron content will also increase. How to greatly improve the grinding production capacity of quartz powder and reduce the iron content in it at the same time becomes a technical problem that must solved for the large scale production of quartz powders.
Vertical mill is a highly efficient and energy-saving machine with the functions of both drying and grinding researched and developed on the basis of widely absorbing foreign advanced technologies and combining with the application experience of vertical grinding mill in domestic and foreign market. It is integrated with tertiary crushing, drying, powder grinding, powder separation and conveying and has the advantages of high powder grinding efficiency, low energy consumption, big drying ability, easy control of the product fineness and simple production process. In addition, the output is 10-12t/h, the mechanical iron containing in the final products is easy to be removed and the iron content and the main technical and economic indexes can meet the customers demands.
