High pressure grinding rolls. A high pressure grinding roll, often referred to as HPGRs or roller press, consists out of two rollers with the same dimensions, which are rotating against each other with the same circumferential speed. The special feeding of bulk material through a hopper leads to a material bed between the two rollers.
Several hundred tower mills have already been installed, while over 150 high pressure roller mills are at work pregrinding or fine-grinding cement clinker, limestone, burnt lime and other brittle materials, with energy savings compared to ball mills of 30% to 50%.
RHP is an high pressure roll mill: unlike a coventional roll mill, the compression of the material against the rolls allows the fine grinding, not a simple lamination. "Auto-comminution allows the transformation of about 50% of the supplied energy into usefulenergy for grinding. In a tubular mill this value is only 20%."
HPGR technology is a qualified alternative for large-scale comminution circuits and is becoming ever more popular in minerals processing. The technology's working principle is that two counter-rotating grinding rolls expose a column of material to high pressure, which …
high pressure grinding roll | crushing process. High Pressure Grinding Rolls (HPGR) as a new grinding technology, was introduced in 1984. Since then, they have been successfully installed in a huge number of plants …
The high-pressure roll mill, HPRM, is an example of continuous grinding under the confined particle–bed mode (Kellerwessel, 1990, Fuerstenau and Kapur, 1995). However, a completely confined particle–bed mode of grinding is difficult to attain in the HPRM because of the well-known end effects that invariably result in some leakage of the feed.

In a high-pressure roller press, two rollers pressurize the material up to 3,500 bar, improving the grinding efficiency dramatically and significantly reducing energy consumption. High-pressure roller presses are most often used to expand the capacity of existing grinding mills, and are found especially in countries with high electricity costs or with poor power supply.

To make the mill more efficient, some roll mills are equipped with a system allowing to garantee a high pressure (10-50 bar) in between the rolls. It is also mandatory for these mills to have a spring system allowing to release the pressure if the constraint is too important (foreign body for example) and avoid mechanical damages.
High capacity High Pressure Grinding Rolls for all your use cases. During its relatively short history in minerals processing, HPGR technology has undergone significant development in machine roll wear surfaces and control philosophy.
