Millis essential and widely used equipment for raw material crushing. Its main component is a cylinder with bigger diameter and smaller length which is revolved by transmitting machinery. Materials are put in cylinder through the feed opening and then thoroughly grinded.It is ahightechnological enterprise that integrated research , manufacture, sales and service .

Mining High PressureGrindingRolls(HPGR) ... The Bondball millgrindability test measures hardness as an index, regardless of the feed size, so it does not give credit for the additional fines. Therefore, the index itself is ignored in the analysis and the results are assessed in terms of throughput rate or specific energy requirement.

High pressuregrindingrolls(HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotatingrollers, one of which is in a fixed position and anotherrollerthat is floating. The two rotatingrollersgenerate such ahigh pressurethat it grinds the feed material to the desired smaller grain size.
