“When it comes to mining, chrome will be a perfect application for the HRC TM 8. In this application, pre-milling – the need to take material down to a minus 5 mm size – has traditionally been done with impactors. While the capital cost of going the impactor route seems favourable, this is outweighed by the exorbitantly high wear costs, especially when dealing with highly abrasive ores,” says Marais. “We therefore also see a big opportunity for the HRC TM 8 in lithium, a highly abrasive ore, where it will be more effective than traditional cone crushers. With its robustness and longevity of wear components, the HRC TM 8 will significantly reduce the cost of producing a minus 5 mm product,” says Marais. Key features and benefits One of the major characteristics of the HRC TM 8 is its versatility. It delivers great performance across applications including mining, industrial minerals, manufactured sand and recycling. The machine offers easy and versatile adjustable product gradation. The production gradation does not depend much on the adjusted space between the rolls, but on the choke feed condition and the constant pressure. Pressure can be adjusted to regulate the product gradation curve. This feature allows the customer to meet any product gradation specification requirements for the desired fine size material. To remain profitable in the face of declining ore grades, mines are increasingly looking for efficient comminution technology. By using a combination of high pressure and a unique patented
Pilot Crushtec International is launching the Metso HRC™ 8 high pressure grinding roll (HPGR) in southern Africa.
