Quick roller exchange without disassembly of feed chute/hopper Skewing is a vital feature for high pressure grinding rolls as feed variance, segregation and the presence of tramp materials are inevitable in real world grinding circuits and will lead to uneven grinding and selective wear of the tyresHPGR or highpressure grinding rolls have made broad advances into nonferrous metal mining The technology is now widely viewed as a primary milling alternative, and there arc a number of large installations commissioned in recent years After these developments, an HPGR based circuit configuration would often be the base case for certain ore types, such as very hard, abrasive ores HPGR High Pressure Grinding RollsPOLYCOM® highpressure grinding roll The proven energysaving grinding system One of the principal reasons for the outstanding success of the highpressure grinding roll in the cement industry is its low power requirement Today, this mill is employed all around the world for the grinding of cement raw material, cement clinker and granulated POLYCOM highpressure grinding rollThe highpressure interparticle comminu tion in the POLYCOM®is based on the following principle: Brittle material particles are fed to the POLYCOM®through a feed bin 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 rollPOLYCOM highpressure grinding rollHigh pressure grinding is achieved by an advanced type of grinding roll Contrary to conventional crushing rolls, the particles are broken by compression in a packed particle bed, and not by direct nipping of the particles between the two rolls This particle bed is First choice for HPGR technology and service
