Metso’s unique take on this technology, the HRC™ HPGR, delivers even bigger – as the most advanced high pressure grinding roll on the market. The technology HPGRs utilize two counter-rotating tires – one fixed and one floating – in order to effectively crush ore. Hydraulic cylinders apply very high pressure to the system, causing inter-particle comminution as the feed travels between the two tires. A focus on

Contrary to popular belief, high pressure grinding roll technology is not ‘new’, having its genesis in the early 20th century as a method of coal briquetting (Figure 1), and being used in comminution applications since the mid 1980s. However, while HPGR is now commonplace in the briquetting, cement, diamond, and iron ore sectors, its adoption for

The technology's working principle is that two counter-rotating grinding rolls expose a column of material to high pressure, which is distributed across the gap between the rolls. Interparticle comminution is the HPGR specific grinding process in which material particles are crushed and ground within the compressed material bed and not by
