What's more, the energy consumption of raw material grinding in the wet process is reduced by nearly 30%. Disadvantages: the heat consumption of the wet process is too high, usually between J/kg and the consumption of ball mill vulnerable parts is also large. Compared with other processing methods, the clinker manufactured by the ...

A method and apparatus for making highly pure silica powder by milling the substantially pure SiO 2 charge in a ball mill which is made with an interior lining of contiguous silicon nitride plates or tiles and which employs silicon nitride media. The silicon nitride plates and media prevent contamination of the silica charge while minimizing their deterioration.

Yttriareinforced copper matrix composites were prepared by dry ball milling (DBM) and wet ball milling (WBM), respectively, followed by spark plasma sintering (SPS). It is to determine which milling process is better for fabricating CuY2O3 composites. It is found that CuY2O3 composites synthesized by DBM exhibit better densification, mechanical and electrical properties than those by ...
