Compared to the pre-grinding systems including ball mills with high energy consumption and low efficiency, these cement mill roller presses consume less energy and produce lower noise. This roller press can improve the grinding capacity by 50- compared to ball mill systems and reduce the power consumption of the grinding system by 30-40% ...

The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x ...

A ball mill is a grinder which is used to grind, blend and mix materials like chemicals, ores, pyrotechnics, paints, mineral dressing process, paint and ceramic raw materials. Its working principle is impact and attrition. Ball milling have proved to be effective in increasing solid-state chemical reactivity and production of amorphous materials.
