Efficiency and grinding media filling level IEEE

Apr 19, 2013 Ten to fifteen years ago two events took place which seemed to support the results of the preliminary investigations of low level filling and efficiency. In the first case, one of the drives failed on a dual drive ball mill operating with a High Pressure Grinding Roll (HPGR) (1). Since delivery time for parts to repair the damaged drive was lengthy, a decision was made to reduce the charge in the ball mill.

Optimization of mill performance by using SciELO

Optimization of mill performance by using online ball and pulp measurements. In the platinum industry, by increasing the solid content in the slurry, the product becomes finer. At a higher percentage solid than 73 to 74%, the product becomes coarser again. At this level, a drop in grinding efficiency occurs.

The use of a mixture of balls and pebbles to reduce power

It is envisaged that recycled pebbles (with a size range of say 19 to 75 mm), which are normally crushed, can be more usefully used in combination with balls in the secondary mill(s). Mixtures of steel balls and pebbles were tested using a 0.57m diameter mill and the results were compared to.

Efficiency and grinding media filling level IEEE

Apr 19, 2013 About 60 years ago, Fred C. Bond, George Krouse, and a few others involved in comminution research conducted some preliminary studies on low filling level of grinding media in laboratory ball mills. Initial indications were that there was a very good possibility for increased efficiency if ball mills were run with drastically reduced filling.
