TOWER FINE MILLING EXPERIENCE AT MOUNT ISA MINES

mills, more reliable, and easy to operate and maintain. Tower mill grinding efficiency drops as feed material becomes finer then 25 microns due to high ball/particle size ratio. Fine grinding efficiency greatly increases with finer media and slightly with denser slurries. To achieve efficient grinding, closed circuit with hydrocyclones is needed.

Tower mill Wikipedia

A tower mill is a type of vertical windmill consisting of a brick or stone tower, on which sits a wooden 'cap' or roof, which can rotate to bring the sails into the wind.. This rotating cap on a firm masonry base gave tower mills great advantages over earlier post mills, as they could stand much higher, bear larger sails, and thus afford greater reach into the wind.
