Feb 01, 2006nbsp0183321. introduction. sch246nert 1979 has shown that the most energy efficient method of comminuting particles is to compress them between the two plates. compressing a particle bed between two counter rotating rolls was achieved by the invention of the high pressure grinding rolls hpgr sch246nert and knobloch, 1984.the first commercial application of hpgr was in 1985 and its success
Since the high pressure exerted along the roll varies and changes like a parabola, it is necessary to divide the roll length into several blocks. in each block a special compressional force is exert-ed related to pressure curve. therefore, each block has a specific consumption power and a specific grinding kinetics. the total length of the roll is
High pressure grinding roll hpgr technology is very rapidly gaining a wide acceptance within the mineral processing industry. benefits, including a superior energy efficiency and a lower overall operating cost of an hpgr based circuit compared to alternative technologies have been demonstrated at a number of operations throughout the world.
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.
Hpgr technology is a qualified alternative for large-scale comminution circuits and is becoming ever more popular in minerals processing. the technologys 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.
