The HPGR was introduced to minerals industry as a replacement for tertiary crushers, SAG mills and rod mills. In some applications it appears as a pebble crusher in AG milling. HPGR has attracted the attention of many researchers for around two decades, resulting in various modeling approaches for throughput or size reduction of the equipment.

The Autogenous/Semi-autogenous Grinding Mills are in most cases used as primary crushers. AG Crushers use the ore exclusively as their grinding media. In case the hardness and the abrasiveness of the Ore is not suitable enough to carry out the grinding process, steel balls are added in-order to assist the process; these are called SAG Crusher.

However, the inter-particle compression of a HPGR is highly effective at reducing competent ores when deployed for tertiary comminution, significantly increasing the throughput of downstream mills while reducing the circuit's overall energy consumption by up to 40%. That's right: circuits with a HPGR simply do more for less.
>Model:Bond HPGR and ball mill - SAGMILLING
Simulating HPGR has two differences from a classical SSBM circuit with cone crushers: first is that the crusher product tends to be finer (~4 mm versus 9 mm) and the nature of the product is different. To simulate an HPGR and ball mill circuit, choose the HPGR - BM flowsheet and the Bond/Rowland single stage ball mill model.
