Ball mill is widely used in building material, and chemical industry. There are two ways of grinding: the dry way and the wet way. Ball mill can be divided into tabular type and flowing type according to differentexpelling mine. To use the ball mill, the material to be ground is loaded into the neoprene barrel that contains grinding media.
Grinding media may be either pebbles, rock, or the new development known as Coors Alumina Ceramic high density grinding media. The media charged to a pebble mill should be between 50% to 55% of the mill volume.

A method and a system are disclosed for maintaining optimum throughput in a grinding circuit of the type in which fresh ore is fed to a rod mill and the ground ore from the rod mill, together with the ground ore from a ball mill operated in a reversed circuit, are combined in a pump box and pumped to a cluster of hydrocyclone classifiers.
Example calculation Estimate the quantity of cement, sand and stone aggregate required for 1 cubic meter of 1:2:4 concrete mix. Ans. Materials required are 7 nos. of 50 kg bag of cement, 0.42 m 3 of sand and 0.83 m 3 of stone aggregate.
In one mill 5000 lb. of pebbles are used to one ton of talc in a mill revolving for 5 to 7 hr. at 22 r.p.m. In roller mills, which are continuous in operation, equipped with air separation, when the talc is ground sufficiently fine it is automatically removed, so that the full crushing effect is continuously applied to the coarser material.
Industrial ball mills can be as large as 8.5 m (28 ft) in diameter with a 22 MW motor, [4] drawing approximately 0.0011% of the total world's power (see List of countries by electricity consumption). However, small versions of ball mills can be found in laboratories where they are used for grinding sample material for quality assurance.
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
A ball mill is simply a container that is filled with pebbles (either of porcelain or stones e.g. Flint) into which a charge (powder or slurry) is put and that is then mechanically rotated to cause the tumbling pebbles to crush particles that happen between them. Ball mills can be continuous or periodic, they can be small or gigantic, low speed ...
