Raw Mill and Cement Mill are essentially two different processes in a cement plant. Raw Mill is mainly used to grind raw materials into fine powder, whereas Cement Mill is used for grinding clinker and other additives to form the final cement product. The main difference between the two lies in their respective input materials; …

Cement manufacturing -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 mill - Wikipedia. Re: Speed of air inside on a cement mill. I will answer you only first question: a typical average of air speed in a tube mill is between 1.0 and 1.5 m/s. If you have a static separator the speed could reach up 2.5 m/s. Best regards, Ariel . Reply

What is a Cement Mill? (with pictures) - wiseGEEK 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.

A gas speed of 4-5 m/s exit drop-out box and a mill speed of 1.5 m/s generally gives a blaine of the aspirated dust of ~3000 cm²/g (Beat Stocker). A gas speed of 2-2.5 m/s exit drop-out box (mill speed 0.5 m/s) gives a blaine of ~4000 (Beat). Discharge Duct. Typically we find that the discharge vent duct is sized for about 10 to 15 m/s.

Power requirement is very high. Speed control ratio is 1:10. Very low creeping speeds of 1 rpm may be required. Starting torque should be in the range 200 to 250% of full load torque. The acceleration of the drive should be completed in about 15 s. For small periods an overload capacity of 200-250% may be required.
