• Production capacity of the grinding mill per unit. This parameter refers to the amount of ore processed by the grinding mill per hour at a given ore feed and product size, t/(unit •h). • Volume capacity of the grinding mill per unit.

Eight Parameters About Hydrocyclone - Xinhai

7. Feed pressure. The feed pressure has a direct influence on the processing capacity and separation particle size of the hydrocyclone. Normally, the feed pressure should be maintained at 49-157 kPa. Increasing the feed pressure can reduce the classifying granularity and increase the processing capacity.

PGM Ore Processing at Impala's UG-2 Concentrator

However, largely, the PGM are finely disseminated, the average grain size being about 10 microns, so that grain size, liberation and association tend to dictate mineral floatability. Platinum group mineral grain size and association can be split into four categories: • Coarse PGM (roughly 5% of all PGE) • PGM associated with base metal and

relationship, overall PGM recovery. The particle size of the PGMs is shown in Table II. The interest in mainstream fine grinding, MIG, and ultra fine grinding of primary flotation concentrates, UFG, is easily illustrated. The tailings' average PGM particle size at an estimated P50 …

Effect of Grinding Media Shapes on Breakage Parameters ...

Sep 19, 2007· Higher breakage rates were noted with cylpebs than with balls. Furthermore, it was found that the primary breakage distribution function is dependent on the feed size (i.e., non‐normalizable), but independent of the grinding media shape. The effect of grinding time on the product size distribution has also been investigated.

circuits. "Coarse" in this case is defined as spanning the size range from a P80 of 750 microns up to the P80 of the product of the last stage of crushing or HPGR size reduction prior to grinding. "Fine" covers the size range from a P80 of 750 microns down to P80 sizes typically reached by conventional ball milling, ie about 45 microns.
