·The crusher was then retrofitted with hydraulic cylinders to increase the pressure between the rollers This was the predecessor to the high pressure grinding rolls HPGR crusher which became popular in Europe for applications in the cement industry The introduction of the HPGR in minerals processing sparked at the beginning of the 2000s
·Mineral processing involves the liberation and concentration of economical metals and minerals from mineral resources for metal extraction Lottermoser feed pulp is pumped through an orifice pipe into the downcomer reactor creating a high pressure jet This high pressure jet of pulp entrains air that is being naturally aspirated into
Two main types are indicated The first type where the rolls are rotated in opposite direction with one roll spring loaded Here the mineral particles are nipped and crushed as they pass between rolls In the second type known as high pressure grinding roll HPGR the mineral sizes are reduced by compressive and interparticle pressure
·In addition the high pressure grinding roll can reduce breakage size from 10 20mm down to 3mm or below in comparison with conventional crushing and grinding equipment thus leading to less energy consumption for grinding process The minerals crushed by high pressure grinding roll have large quantities of microcracks along the grain boundary
·High pressure rolling has been extensively studied in experiments for mitigating RS and distortion in WAAM Colegrove et al [5] The stacked four layer rolling process is implemented with fewer rolling operations than the inter layer rolling Fortunately it has larger influence depth than the deposition and thereby leads to longitudinal
