Particle size reduction of pigments by nonsalt milling

Particle Size Reduction Of Pigments By Nonsalt Milling

The ball mill is then sealed and rolled for a period of time sufficient to reduce the particle size of the pigment to less than about one micron. Generally, about 2 to 24 hours is sufficient, although longer times may be used. The time of agitation is not critical, so long as the time is sufficient to achieve the desired particle-size reduction.

Investigations were carried out in a laboratory ball mill having the size of DxL 160x200 mm with a ribbed inside surface of the drum. The mill ball loading was 40 by volume, the rotation rate was equal to 85 of the critical speed. Balls were made from steel S4146, extra high quality, having hardness 62 2 HRC according to Rockwell.

Material Particle Size Classification Equipment

Material Particle Size Classification Equipment

In the past, mechanical classifiers were usually selected to operate in closed circuit with grinding mills. These devices require much floor space and have been essentially replaced in large plants, as well as small, by hydrocyclones. Since classification is a potential plant bottleneck, it is recommended that the cyclone feed system be provided with redundant pumps. It is relatively ...
