Unless it is entirely necessary dry concrete grinding is much better for the environment than wet concrete grinding. Wet grinding leaves slurry – a mixture of cooling water and concrete fines. It takes a lot of time to clean the slurry, and safely disposing of it without negatively impacting the environment is a significant challenge. Wet ...

Cement Manufacturing Process. 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.

Clinker is the intermediate product used in the manufacturing of cement. There are two primary processes used to manufacture clinker: the dry process and the wet process. Our plants use the dry process, which is more energy efficient. In the wet process, the raw materials are mixed with water to form slurry, which is fed into a kiln.
