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 classifiion is a potential plant bottleneck, it is recommended that the cyclone feed system be provided with redundant pumps.
