REVIEW OF PARTICLE-SIZE CLASSIFICATIONS OF SOILS

A review of particle-size classification systems for soils is made. Early systems and the evolution to systems now in use by agriculturalists, engi­ neers, and geologists are presented. Thirty-two systems are given, and where possible the reasons for the various particle-size ranges and name designations are given.

Material Particle Size Classification Equipment

2022-1-1  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
