4 times (A1 powder) and times (A2 powder). These results show that the milling process is a useful method for activating the amorphous silica powder surface without breaking the particles. To keep the original particles structure without sintering is necessary in some appliions. 4. Summary and conclusions
They operated the fist ball mill grinding plant with nearly 24 hours every day in the whole year, and few stop to do maintenance. So they gave us second order with bigger capacity, under the solution we provided that *8m ball mill with ASS830 single wheel classifier with 400mm diameter, mainly produce silica and feldspar with 38 micron, 45 micron and 100 micron with about /hour, 3 ...

(a) Nitrogen adsorption isotherms of samples ball milled at various periods, (b) specific BET surface area of silica powder versus milling time.
As the powder is extremely fine it poses real problems due to dusting. Long processing times are required to fully disperse the powder once it is wetted out. Low shear mixing devices are generally unsuitable for dispersing fumed silica. While the powder may be wetted out, the lack of high shear mixing results in poor yield of thickening effect.

· Attrition mills are more appropriate for "midrange" size particles. Such mills utilize 3–10mm media to produce material ranging in size from approximately 1 to 10 microns. The first "small media" mill was introduced about 60 years ago. It was named a "sand mill" because it used 1/64–1/8 in. Ottawa silica from Canada.
The development of powder metallurgy technology has affected the increasing demand for powder materials lately. The powder production process uses physical methods, such as grinding with a ball mill more effective and more environmentally friendly than other methods. The parameters used in the ball mill process are relatively large, however there are several parameters that have a significant ...
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (, via a hand crank), working animal (, horse mill), wind or water ().
