Cement mill

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 /g

Sep 25 2018In dry process all the materials in powder form are ground separated in the absence of water and then mixed in the desired proportion and the resultant product is fed into kiln for burning This process results less consumption of energy And low

In 1995 there were 252 installations producing cement clinker and finished cement in the European Union and a total of 437 kilns but not all of them in operation In addition there were a further 68 grinding plants (mills) without kilns In recent years typical kiln size has come to
