Cement mill Wikipedia

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. History. Early hydraulic cements, such as those of James Parker, James Frost and Joseph Aspdin were

Raw Material Preparation Cement Plants and Kilns in

From the early 1900s, both for cement grinding and for grinding hard raw materials, whether by wet or dry process, the standard arrangement was a ball mill for preliminary grinding (to below 0.75 mm), followed by a tube mill for fine grinding. Typically the ball mill was placed on an upper floor so that material could move by gravity. An example was the original rawmill system at

Energy consumption and output. Cement mills are normally driven by electric motors. Modern installations draw power of 2-10 MW. The power (in kW) required to turn a ball mill is approximated by: P = 0.285 d (1.073-j) m n where d is the internal diameter in metres, j is the fraction of the mill volume occupied by media, m is the total mass of media in the mill, in tonnes, and n is the mill

OPTIMIZING THE CONTROL SYSTEM OF CEMENT MILLING:

For productivity and quality reasons, grinding is mostly performed in closed circuits: The ball cement mill (CM) is fed with raw materials. The milled product is fed via a recycle elevator to a dynamic separator. The high fineness stream of the separator constitutes the final circuit product, while the coarse material returns back to the CM to be ground again. A simplified flow sheet,

What does a cement plant of the future look like? (Part 2)

Grinding cement requires a great deal of energy. As the fineness of the cement increases, it needs more energy to grind it. But every cement quality band has a certain fineness requirement. In one example mill, we consider the fineness and the energy consumed for eleven months for a cement mill. In the first five months, we found that this
