Material Particle Size Classification Equipment
Since classification is a potential plant bottleneck, it is recommended that the cyclone feed system be provided with redundant pumps. It is relatively straightforward to design a split sump so that mill discharge may be deflected to one side or the other and thence to the appropriate feed pump. Care must be taken to insure that the cyclone ...Web
