Mills belong to a class of equipments that accomplish comminution of materials in the fine range. There are two types of mills which are mostly used in cement plants for grinding raw mix viz. Ball mills and VRM. Ball mills Ball mills are essentially fine grinding units capable of grinding material to a fineness say 84 passing 90 microns.
Grinding cement in ball mills. The principle of the ball mill operation is simple it consists of a rotating drum and grinding media cylinders balls etc. The material is placed into the drum which starts rotating. The grinding media and the substance both come in circular motion and at a certain point drop from the walls the bottom of the drum.
The ball mill is the key equipment to crush the material after being crushed. This type of mill is equipped with a number of steel balls in its cylinder as grinding medium. It is widely used in cement silicate products new building materials refractories fertilizers black and nonferrous metal beneficiation and glass and ceramics industries.
A conventional cement grinding circuit is composed of a two compartment tube mill a mill filter which collects the fine material inside the mill and a dynamic air separator where final product.
Jul 18 2016nbsp018332Cement ball mills typically have two grinding chambers. The first chamber is filled with larger diameter grinding media and lined with lifting liners. The first chamber coarsegrinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding chamber.

The ball mill for clinker is an efficient tool for fine powder grinding. It is mainly used to grind the clinker and raw materials in cement industry and also can be applied in metallurgy chemical electric power and other industries to grind all kinds of ores.
The opencircuit grinding system of the ball mill is shown as follows materials including clinker gypsum mixed materials etc. mixed according to a certain proportion will be directly stored in the steel silo as finished cement products after being ground by the ball mill.
Dec 08 2009nbsp018332Re how to estimate the wear rate for Ball mill. Hey Ball wear can be measured by weighing an entire charge before and after grinding a known tonnage of materials. With new balls sample of given size can be weighed before and after grinding a given tonnage and assuming uniform wear per unit of ball surface the total charge wear can be estimated.
Ball mills are most commonly used in cement factories to grind the raw material and finely grind the cement. The use of ball mills in cement grinding is due to several factors among which are relatively simple design and high processing rate. However these machines have certain limitations as well.
The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 11.5 times the shell diameter Figure 8.11. The feed can be dry with less than 3 moisture to minimize ball coating or slurry containing 2040 water by weight.
