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.

cement industry the ball mill was really an epoch-making breakthrough as for almost 80 years it was the predominant mill for grinding of raw materials and coal, and still today is the most used mill for cement grinding. Over the last three decades the vertical roller mill has become the preferred mill for grinding of raw .
The cement manufacturing process starts from the mining of raw materials that are used in cement manufacturing, mainly limestone and clays. A limestone quarry is inside the plant area and a clays quarry is as far from the plant area as 25 km.
Cement mill is also called cement ball mill, which is mainly used for grinding cement clinker in the cement production process. It is one of the important cement equipment. The output of cement mill is 21~155 t/h, and the specific surface area of cement is 3300~3800 cm ² /g.
A rawmill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement.Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill.The rawmilling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished cement, and has a large effect upon the ...

The rotary kiln line, raw mill and coal mill were being operated by a PLC based central automation system in the plant. In general, it is quite difficult to ensure process control with such a conventional automation system, looking at long term stability and consistency, due to shift-to-shift variations.
Clinker is the raw material used to manufacturing the cement. The clinker plant comprises of feed pre crusher, feed hopper, table feeders, ball mill, packaging cement plant and material handling equipment. However, the operation of the plant consists of basically four processes viz. quarry, raw mill grinding, coal grinding and kiln-burning. ...
