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.
This paper mainly introduces the raw mill in cement plant. In order to achieve the desired setting qualities in the finished product, a quantity (28%, but typically 5%) of calcium sulfate (usually gypsum or anhydrite) is added to the clinker and the mixture is finely ground to form the finished cement powder.
High efficiency and energy saving; With the same finished product fineness and motor power,The yield of limestone mill is up to 200% higher than jet mill, mixing mill and ball mill. Low energy consumption, long service life of limestone mill wearing parts; Its grinding roll and ring adopt special materials, thus greatly improve the durability of .
A ball mill can also be helpful in the process of cold welding, and produces alloys from powders when used in capacity for chemical processing. The ball mill technology is one that is designed for optimal cold refinery, subjecting the machinery to a great deal of distress during use.
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and ...
