11.6 Portland Cement Manufacturing 11.6.1 Process Description1-7 Portland cement is a fine powder, gray or white in color, that consists of a mixture of hydraulic cement materials comprising primarily calcium silicates, aluminates and aluminoferrites. More than 30 raw materials are known to be used in the manufacture of portland cement, and these

- Mill (grinding) - Wikipedia

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

- Energy Efficiency and Saving in the Cement Industry ...

Since the thermal efficiency through the use of this conventional technology of pyroprocessing is slightly higher than 30% on average (Mersmann, 2007), there could be considerable scope for improvements. Grinding and milling account for 5.8% of cement/concrete energy consumption (Choate, 2003).

- The energy efficiency of ball milling in comminution ...

In terms of this concept, the energy efficiency of the tumbling mill is as low as 1%, or less. For example, Lowrison (1974) reported that for a ball mill, the theoretical energy for size reduction (the free energy of the new surface produced during grinding) is 0.6% of the total energy supplied to the mill setup.
