Contact UsFor temperature sensitive products, ball mills can be fully jacketed to maintain temperatures of the product. Ball mills scale up well and in fact improve in performed with increasing size. Ball mills are available in sizes from laboratory scale (also called milling jars) of 0.1 usg to large 5,000 gallon mills.
Contact UsBall mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol. % ore and 25% steel.

This method only gives a rough and initial idea for sizing a cement ball mill. To go ahead, a deeper study is necessary with ball mills suppliers or a specialized engineering office.
Contact UsA 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.
