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.
