A cement mill is the equipment that 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. cement clinker is usually ground using a cement ball mill. this is essentially a large rotating drum containing grinding media normally steel balls.
The capacity chart shows the contribution of semi-continuous or continuous kilns. Hoffman kilns were used to a limited extent during 1880-1900. Shaft kilns of various sorts began in the form of Dietzsch kilns in the 1890s. Various straight-through shaft designs were tried, and there was a considerable surge with the arrival of the Schneider kiln in 1900.

Cement is manufactured through a large-scale, capital-and-energy-intensive process. At the core of the production process is a rotary kiln, in which limestone and clay are heated to approximately 1,450 degrees Celsius. The semi-finished product, clinker, is created by sintering. In the cement mill, gypsum is added to the clinker and the mixture
