Feb 01 20060183321 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 1984The first commercial application of HPGR was in 1985 and its success.
Through historical cooperation with KHD in the manufacture of High Pressure Grinding Rolls HPGR CITIC HIC now designs and manufactures a full range of HPGRs to suit the cement and mineral processing industries With over 170 units sold CITIC HIC has the experience in supplied world class HPGRs to the industry.
Based on a thorough review of the high pressure grinding rolls HPGR and crushing circuit a wide range of debottlenecking opportunities were identified This was followed by a series of surveys to provide performance measurements and to model the circuit in detail From this effort a full simulation of the plant has been developed including.
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 The oil is both lubricant and cooling agent.
The grinding elements are two counterrotating rolls between which the material is crushed One roll is designed as a fixed roll and the other one as a floating roll The required comminution pressure is transmitted via the floating roll The highpressure interparticle comminution produces compacted cakes of material.
High pressure grinding rolls HPGRs also known as roller presses are rapidly gaining acceptance in hardrock processing primarily due to their energy efficiency when reducing mineral ore to fragments ABB AbilityTM MineOptimize ABB AbilityTM MineOptimize is a 4pillar.
