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. High cyclone efficiency greatly improves the performance of the circuit. A new procedure for Tower mill ...

26/12/2017 According to Bond (1954), the grinding efficiency of a mill depends on the ball mill diameter, size of the media and mill speed. Ball mills with different length to diameter ratios for a particular power rating will produce different material retention times. The longer units are used for high retention ratios while shorter units are used where overgrinding is a factor to be considered ...
