It has been reported that stirred mills consume 30% less energy in coarser fine grinding and approximately 50% in ultra-fine grinding regime (Davey, 2006, Rahal et al., 2011). These factors have led to a steady increase in the number of stirred mill installations in various grinding duties of mineral processing plants.reliable roller grinding mills and coal grinding plants in accordance with this motto. Important features here are: • no metallic contact between the grinding parts, even when the mill is empty; thus no sparking • individual guidance of the grinding rollers ensures low-vibration mill operation even in the partial-load range down to 20 %

Atlas The ATLAS is a roller air-swept mill designed for continuous operation with minimum maintenance. The fundamental difference between the ATLAS and other table-roller mills is the bearing arrangement for the grinding table which is incorporated into the base of the mill.The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the ...
