Cement manufacturing: components of a cement plant. This page and the linked pages below summarize the cement manufacturing process from the perspective of the individual components of a cement plant - the kiln, the cement mill etc.. For information on materials, including reactions in the kiln, see the ' Clinker ' pages.

Compared with traditional concrete buildings, metal structure buildings use steel plates or section steel instead of reinforced concrete, higher strength, and better seismic resistance. And because the components can be manufactured in factories and installed on-site, the construction period is greatly reduced.

Cement is the basic ingredient of construction and the most widely used construction material. It is a very critical ingredient, because only cement has the ability of enhancing viscosity of concrete which in returns provides the better locking of sand and gravels together in a concrete mix.

Cement milling is a highly energy-consuming operation in the cement industry, so efficient control is required in order to reduce the specific production costs (kW. h/ton of cement produced) while maintaining the product quality, i.e., cement fineness at an acceptable level.. There exists a nonlinear dependence of the mill product on the mill load (amount of material …

To make cement, the clinker must first be cooled. Prior to being crushed in the cement mill, the gypsum produced in the kiln is separated from the main product stream. The output from the cement mill may be blended with other constituents to meet certain specifications depending on the end use. The packaged product is then shipped to the consumers.

The internal structure of the mill is the main factor. The reasonable division of the length of each silo, the form of the lining, the over-feeding capacity of the silo, and the discharge capacity of the discharge raft are essential. ...
