On the average, mining equipments are composed of crushing machines, grinding machines, beneficiation machines, conveyors, feeders and so on. Grinding machines are a large part in mining industry. In many ores processing lines, grinding machines are used for ores grinding, which have many advantages for the whole processing lines. This article introduces a special grinding machine, that is, cement mill.

A cement mill is an installation used to grind the clinker component of concrete. Clinker is a hard, nodular material produced by sintering aluminosilicate and limestone in a cement kiln. There are several cement mill types which are able to grind clinker of which the ball mill is the most common. Ball mills consist of cylinders partially filled with large numbers of steel balls which employ their rolling action to crush the raw material when each cylinder is rotated. High pressure roller mills are occasionally used to grind clinker although their use has not yet gained broad acceptance.

The chief constituent of Portland cement is a sintering product of limestone and aluminosilicate known as clinker. This hard, pebble like material is the ingredient in cement which causes it to “cure” and harden to form the mortar or concrete used so extensively in construction. The clinker sintering or heat combination process produces a coarse, nodular material of particular hardness which requires fine grinding prior to cement production. Particle sizes of below 45 µm are required which, due to clinker's hardness, requires a particularly efficient milling process. Although there are several mill types capable of grinding clinker, the most commonly used cement mill process is the ball mill.

Our cement mills at domestic advanced level are exported to Vietnam, Indonesia, France, Germany, etc. China cement mills have been honored as famous brand of China building material in machinery industry, national top brand product, fixed-point production of national...
