Cement manufacturing - brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.
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.

Concrete grinders (sometimes called concrete sanders) remove material up to 1/8 of an inch below a concrete surface per pass. Rent a concrete grinder if you need to remove surface materials such as paint, epoxies, stains and other coatings. A concrete scarifier, aka concrete planer or milling machine, removes up to 1/4 of an inch per pass.
A Abrams' Law-The rule of concrete stating that with given materials, curing, and testing conditions, concrete strength is inversely related to the ratio of water to cement.Low water-to-cement ratios produce higher concrete strengths Accelerator - Chemical substance added to a concrete mix that reduces the set time by increasing the rate of hydration.
It is also adaptable to three different types of grinding setups: pre-grinding, semi-finish grinding and finish grinding. The OKTM mill can skilfully grind raw or cement feed material and offers parts commonality, simplifying spare parts inventory and facilitating easy switching of parts between vertical roller mills.
