A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel together.Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete.Concrete is the most widely used material in existence and is behind only water as

While rotary kilns have the ability to remove moisture from a material, this tends to be a less eficient process. In a rotary kiln, material is typically not showered like in a rotary dryer, but rather, slides along the interior of the rotary kiln. This results in lower heat transfer between the material and the gas
