اقرأ أكثرThe function of grinding stones in China is a controversial issue. While many believe that such tools were used typicall y for. dehusking domesticated cereals (e.g., Chen, 2002; Song, 1997),Grinding, with its 0.000025 mm precision in dimensions, is typically used as a finishing operation that removes only a small amount of metal (between 0.25 and 0.50 mm). While grinding can quickly remove large volumes of metal in some roughing applications, this is not the case in most cases. Thus, grinding is a wide-ranging profession.
اقرأ أكثرGrinding Aids. The general use of chemical grinding aids involving several different mechanisms for increasing throughput in the wet grinding of ores has been discussed in a number of recent publications. It appears from industrial scale testing that the use of selective dispersants with certain prespecified operating conditions is an approach ...In other words, dispersants promote and stabilize the suspension of solid particles in the paint medium. All dispersing agents have two parts: Anchoring groups. Soluble tails. The choice of your dispersant will greatly influence the quality of your dispersion. They improve: Milling time and viscosity. Tint strength.
