Application to Cement Grinding. In the last stage of cement preparation, clinker is ground to a very fine powder in order to achieve a suitable compressive strength of the material. It is now well recognized that cement quality is greatly influenced by its particle size distribution, frequently characterized by its specific surface area.

In 1904, Krupp produced a self-contained cement mill using a ball mill and their version of the Askham separator in closed circuit, but I think this was never used in Britain. However, from the mid 1890s, ball mills were used in combination with tube mills (see below) and this setup became the normal cement milling installation until 1920.
(a) particle size reduction, (b) premixing, (c) mixing, (d) pelleting, and (e) sacking. Coarse ingredients pass over a permanent magnet which removes tramp metal and then through a hammer mill which reduces particle size to the desired screen analysis.
8/30/2012· 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.
