planetary ball mill for bauxite grinding process

Studies on Batch Grinding of Bauxite Ore in Ball Mill - International ...

Grinding is the last stage in the process of comminution; in which the particles are reduced in size by a combination of impact, abrasion and attrition of the ore by the grinding media such as balls, pebbles or rods in rotating cylindrical vessels known as tumbling mills [1]. In many industries the final product or the raw materials...

Ball mill - Wikipedia

A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow...
