Rod Ball Mills. The Ball/Rod mills are meant for producing fine particle size reduction through attrition and compressive forces at the grain size level. They are the most effective laboratory mills for batch-wise, rapid grinding of medium-hard to very hard samples down to finest particle sizes. Jul 10, 2020 The rod mill discharge is pumped to the primary hydrocyclones that classify the particles by size. The larger particles flow to feed the ball mills while the fine particles report to two flash flotation cells. The ball mills are in closed circuit, meaning that the discharge is pumped to the classifying units (primary hydrocyclones) and ...
