During Metso pilot testing the operational versatility of HPGR technology was confirmed

Operational versatility of Metso high pressure grinding roll HPGR HRC was successfully proved during the pilot testing which was performed in Chili in 2016 and 2017.

During the development of the projects for increase of process capacities of companies it was important to go beyond the laboratory testing. Pilot tests under real operational conditions help to correctly choose the optimum technologies for specific processes. That’s why several customers who were impressed with the prominent results of operation of the grinding roll HPGR HRC in the USA expressed the wish to test this technology to deal with their objectives of production.

The results of pilot tests of the high pressure grinding roll HRC 800 have proved that the developed solution fully satisfies the operation requirements. In addition to that the pilot specimen confirmed the choice of the standard size defined by Metso experts during laboratory testing. Based on the works performed for process modeling and simulation a list of the equipment  necessary in order to expand the capacities of the customer was made.

"The high pressure grinding roll HRC is without any doubt a leap forward for technologies of the mining industry. The results of pilot tastings are very important: we have not only tested a hypothesis but have realized 100% of the customer expectations. And we expect to receive new requests for testing this innovative technology ", - says Raul Noriega, Capital Equipment Sales Manager at Metso Chili.

Further projects aimed to decrease production expenses

The technology HPGR HRC is highly-performant alternative to traditional high pressure grinding rolls. The results of the pilot tests have shown that Metso equipment allows saving up to 10-20% operation expenses depending on the type of ore. The pilot plant with the grinding roll HRC processes up to 50 tons of gold-bearing and copper ore per hour: the tests in different types of ore allowed Metso experts to test the equipment considering individual requests of the customers. The next pilot tests will take place in Chili this November.
