Abstract: The article discusses the key issues related to the intensification of ore preparation operations and evaluates prospects for modernizing particle size reduction equipment that is used to comminute brittle ores without overgrinding and crush medium-hard nonmetallic rocks, including clay and wet ores. It is proposed to introduce roll crushers and high-pressure grinding rolls (HPGRs) with Reuleaux triangle rollers to mineral processing circuits. The research has shown that this type of rollers is promising for use in ore preparation. To improve comminution efficiency, the ore feed is moved in a vertical reciprocating motion, with ore pieces going in two directions, which leads to an increase in the specific throughput of the crushing unit. In this configuration, the specific compressive force increases by 10%, and power consumption decreases by 10%.
