HPGR High Pressure Grinding Rolls

Jul 13, 2016 Thus, some of the finish grinding work is handled by the high-pressure grinding roll. The throughput of the existing grinding system can be increased by 50 to 70%, while power consumption can be cut by 20 to 30%. Additional options for high-pressure grinding roll use in gold ore comminution circuits are illustrated in Figure 11.

High pressure grinding rolls (HPGR) TON Outotec

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.

This type of mill offers the minerals industry numerous benefits: Safe process technological design. Low operating expenses: in comparison to other systems, both the power consumption and the costs for wear parts are significantly lower. High throughput rates: a high-pressure grinding roll can replace several reduction crushers.

High Pressure Grinding Rolls Crushers, Ball Mills

A hydropneumatic spring system builds up a pressure of up to 250 Mpa. During operation of the machine,it is possible to cchange the pressure and thus change the product fineness. Highly wear-resistant roll surfaces achieve service lives of 4,000 to 10,000 hours when grinding abrasive hard rock.

High pressure grinding rolls (HPGRs, also known as roller presses) are becoming well accepted for coarse, abrasive, and hard rock applications. When the first HPGR for coarse ore was commissioned at Los Colorados in 1998, there were only 14 HPGRs installed in the minerals industry, mainly for grinding pellet feed to increase the Blaine value (Van

High Pressure Grinding Rolls for Minerals

High Pressure Grinding Rolls have been used for the grinding of diamond and iron ores since about 1988. There are now about 40 machines operating world-wide in these industries. This number is still small in comparison to the > 450 machines employed in the cement and raw mate-rials industry.
