A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
In this process, the hydrated cement reacts with CO 2 in the air, slowly reversing some of the processes that took place in the kiln when the cement was made (this is the carbonation process; it also causes reinforcement corrosion, see Section 25.3.2). It is estimated that this may reduce the carbon footprint of the cement industry by 3–5%.
Step 6 : Finish Grinding. The clinker is ground in a ball mill—a horizontal steel tube filled with steel balls. As the tube rotates, the steel balls tumble and crush the clinker into a super-fine powder. It can now be considered Portland cement. The cement is so fine it will easily pass through a sieve that is fine enough to hold water.

The power used for the actual grinding process while grinding raw materials, depends mainly on the hardness of raw materials and the type of mill used, i.e. ball mill or vertical roller mill. Typically, the motor of the ball mill consumes about 14 - 15 kWh/ ton of raw mix whereas the VRM motor uses 7 - 8 kWh/ ton.
The last step in manufacturing cement was the finish grinding. The clinker was first recovered from the storage area and fed into a cone crusher for reduction to a 3/8 inch screen size. The crushed clinker was then conveyed to one of two 5,000 barrel silos used to feed the main finishing mill.
Finish Mill. The final process of cement making is called finish grinding. Clinker dosed with controlled amount of gypsum is fed into a finish mill. Typically, a finish mill is a horizontal steel tube filled with steel balls. As the tube rotates, the steel balls are lifted, tumble and crush the clinker into a super-fine powder.
Continuously measuring the quality of cement manufacturing in real time has been an impossibility since any measuring instruments that might be installed inside a mill would be destroyed. As a result, cement manufacturers have had to rely on a manual sampling process performed on finish product, and then testing the fineness and residue of the ...
Portland pozzolana cement is suitable for concrete works underground, in water, or humid environment, especially for projects requiring impermeability, freshwater resistance, and sulfate corrosion resistance, such as hydraulic structures, marine structures, dam construction, construction near the seashore, sewage disposal construction, etc.

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.
