The Cement Manufacturing Process. The production of cement involves a series of steps that transform raw materials into the final product. The process begins with the crushing and grinding of raw materials, followed by the formation of clinker, and concludes with the grinding and mixing of clinker to produce cement.

Cement milling is the process of grinding together cement clinker, gypsum and other additives to produce a fine grey powder. The resulting material, called "cement meal", is then heated in a rotary kiln to around 2,000°F to produce the finished product known as Portland cement, which can be used for many different construction purposes.
