2016-6-3 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.

2019-3-15 A trial was carried out using the 17 mm grinding media to improve the grinding efficiency. One of the TowerMill was charged with the 17 mm high Cr grinding media. Circuit survey was carried out in two TowerMill circuits, i.e. one mill was charged with the original 20 mm grinding media and the other one was charged with 17 mm high Cr grinding media.

The IsaMill is challenging the way that plants are designed and operated. This paper challenges existing designs of concentrator flow sheets, particularly focusing on magnetite circuits. From what has started out as a small scale ultra fine grinding mill in the pharmaceutical and pigment industries, it has been redesigned and improved upon for mineral processing, and has been the mainstay of ...

The tower mill here was running in parallel with one of the ball mills. The feed entering the tertiary system is scalped in a primary cyclone. The finial cut is made in a secondary cyclone. The actual feed to the tower mill is the underflow from the two cyclones and was split to the ball mill and tower mill.
