Vertical agitated media mill for energy efficient fine grinding The EIRICH TowerMill combines the benefits of: Energy efficiency High throughput High availability even in abrasive applications Reduced operating costs Features The EIRICH TowerMill product family ranges in installed power from 10 hp to 1,500 hp / 7.5 kW to 1,120 kW with throughputs from 0.5 up to 400 metric tons per hour. EIRICH TowerMill Robust design The TowerMill’s main components are the grinding chamber and the agitator screw. The grinding chamber The vertical cylindrical grinding chamber is the heart of the TowerMill where comminution of mineral bearing ores takes place. Like all agitated media mills the grinding chamber is charged with spherical grinding media. The media can be either steel or ceramic balls, depending on the downstream process and end product desired. The grinding media is used by EIRICH’s unique and cost-effective autogenous grid liner system to prevent wear on the inner surface of the grinding chamber. The grid liners, available in carbon steel, acid-resistant steel alloy, or wear-resistant polyurethane, make use of the centrifugal forces and hydrostatic pressure within the mill chamber to trap and hold an outer layer of grinding balls. These stationary balls protect the mill against abrasion by the balls that are in motion. The agitator screw The agitator screw brings the media charge in the grinding chamber into motion. The screw is rotated at an application-specific speed by means of a premium-efficiency electric motor coupled to a planetary gear reducer and a vertical drive shaft, all located above and external to the grinding chamber.
