PDF | The issues concerning operating parameters of HPGR were presented in the article. The HighPressure Grinding Rolls technology is currently the most efficient method of crushing in hard ore ...
High Pressure Grinding With our Roller Presses, the grinding pressure is transferred from the hydraulic system via the movable roll to the material bed and absorbed in a stable, closed machine frame. A key feature is the mounting of the rollers in oillubricated cylindrical roller bearings.
Ring or disc mills use both inside and outside surfaces of a rotating circle for grinding. HPGR (high pressure grinding rollers), roll, or roller mills pulverize material as it moves between two large rollers or a roller and a flat surface. The rolls can be serrated, toothed, or smooth.
A major technological breakthrough came with the introduction of highpressure comminution in the mid1980s. This innovative application for the cement and minerals processing industries required a completely new approach to the question of wear protection for these high pressure grinding rolls .

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.

Köppern – Specialists in HighPressure Comminution 7 Improved CostEfficiency Highpressure grinding roll presses (HPGRs) are emerging as an important comminution technology in the minerals processing industry. The technology has found its key application in the liberation of diamonds and also in primary comminution.
The roller, which is hung by bearing and pendulum shaft, will roll along the inner circle of the roll ring while the hanger is rotating. A dust removal blower will generate negative pressure at the inlet and outlet of the grinder to prevent dust and radiating the heat in the machine. History
It has the same working principle as Raymond Mill, but its grinding device is fixed with 1000 1500 kg pressure springs. When the machine works, the grinding roller, under the action of high pressure spring and centrifugal force, rolls close up to grinding ring, its rolling pressure is times higher than that of Raymond mill given an identical condition and its output may increase 20% to ...
