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.

Mills usually operate in the range 65 - 82% of critical but values as high as 90% are sometimes used. A crucial parameter that defines the performance of a mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating.
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.

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 Roll. High pressure grinding roll suitable for compression strength less than 300Mpa, humidity less than 35% of the hard, medium hard and soft materials, fine and intermediate crushing. Can be widely used in mining, thermal power, cement, ceramics, metallurgy, chemicals, building materials, etc.
If HPGRs are operated correctly, ball mills can be downsized and use smaller grinding media, which substantially reduces steel ball consumption, increases the grinding efficiency and lowers operating costs of the milling substantially. The use of HPGR technology also promotes micro fracturing, which can expose minerals encased or locked within a particular ore.
High-pressure air, gas or steam is introduced through specially designed nozzles, converting the potential energy of the compressed gas into a grinding stream of sonic or supersonic velocity. This elastic fluid creates a high-velocity helix that rotates around the center of the mill. Raw materials are introduced into the grinding chamber
