Circuit Capacity of HPGR

The capacity of an HPGR circuit, as distinct from the unit capacity discussed above, is obviously a function of the circuit design. Of the above variables, the feed bottom size is particularly relevant in this regard, as a truncated feed necessarily implies the pres- ence of a screen or other classification device upstream of the HPGR.

HPGR High Pressure Grinding Rolls

HPGR or high-pressure grinding rolls have made broad advances into nonferrous metal mining. The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years. After these developments, an HPGR based circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores.

1/1/2016· Capacity of Roll Crushers. The capacity Q of roll crushers is directly proportional to its width, W, diameter, D and speed of revolution of rolls . The production capacity of HPGR can be taken as the volume of material passing through the gap between two rolls. It therefore depends on the width of the rolls, the working gap and the velocity of material through the gap. The mass flow rate

HPGR High Pressure Grinding Rolls Weir

With their excellent throughput capacity, low maintenance requirements and energy efficiency, HPGRs are fast becoming the go-to technology for greenfield projects. What is HPGR? Used in mining applications for the last 30 years, high pressure grinding rolls (HPGR) reduce particles by compressing and crushing the feed between two counter rotating, parallel rollers with a small gap between them.
