Different machines to meet all needs
Mill drives We offer both high-speed induction and low-speed synchronous motors. High-speed motors require an intermediate gearbox. Although large mills exceeding 18,000 kW normally use gearless drives, Outotec can offer geared drives in excess of 24 MW. Smaller mills up to 450 kW are also available in a direct-driven arrangement.

High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size.

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 contact with the roll surface.
