Three processes making zircon sand fines

　　 Zircon sand fines has a good opacifying effect, so 10%～20% of it is used in ceramic glaze opacifier. But high-grade zircon sand fines in the market of our country almost depends on importation and the price is very high. Zircon sand produced by demestic manufacturers affects the opacifying effect in the glaze because distribution range of fineness and size don't meet the requirements. Researchers compare and analyze the three production processes of zircon sand fines produced in domestic and put forward their view about producing zircon sand fines.
　　 Milling time of three processes producing zircon sand fines is 16 hoours.
　　 1. Wet grinding process has the best sanitory condition. But in the actual production process, especially when the work is interrupted suddenly (power failure and machine repair), wet grinding process is very easy to precipitated, not easy to flotate, often affects the quality of products, even makes the products not qualified and affects the economic benefit seriously.
　　 2. The characterristics of dry ball milling is that it does not need to evaporate water and reduce the pollution of water with single process and better size range.
　　 3. Dry and wet milling mixing process dry grinds zircon sand and prepared compound grinding aid for a while at first, adds water and grinding aid to wet grind after coarse materials reach fineness with a certain degree. This process has the best effect in the same milling time. Its limitation is increasing the process of grinding aid with water during the milling process.
　　 Superfine pulverization technology of zircon sand is different, quality of products is different and economic benefit ia also different.
　　 Expremental research of superfine pulverization process shows that dry and wet miximg process has a better effect when the size into the mill is bigger. Dry superfine pulverization process has the best effeact and economic benefit when using grinding aid in a proper way.
　　 Superfine pulverization expremental research of zirconium silicate provides the above three processes, you can select the best process according to the actual situation of plant and quality requirement of products from users.
