Grinding Media in Ball Mills for Mineral Processing
The grinding efficiency of a ball mill is determined by the product size distribution, energy consumption, and the grinding costs. According to Hassanzadeh, about 37% of the costs are used for grinding media only,13% for liners, and about 50% is used for energy in an industrial ball mill. This is evidence that media consumption has its fair ...
