What Is Cement Mill

what is a cement mill? (with pictures),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..the cement mill,brief description of a cement mill. cement clinker is usually ground using a ball mill. this is essentially a large rotating drum containing grinding media - normally steel balls. as the drum rotates, the motion of the balls crushes the clinker. the drum rotates approximately once every couple of seconds..cement milling - understanding cement,cement milling. cement milling is usually carried out using ball mills with two or more separate chambers containing different sizes of grinding media (steel balls). grinding clinker requires a lot of energy. how easy a particular clinker is to grind ('grindability') is not always easy to predict, but large clusters of belite due to coarse silica.how to read a cement mill certificate: part 1 - npca,when we buy cement, we are provided with a cement mill certificate by the cement producer. cement mill certificates, also called mill test reports, contain a lot of information that can prove useful for tracking changes in your concrete and controlling variability in your mix..
