Aug 20, 2015 There are more than twenty types of cement used to make various specialty concrete, however the most common is Portland cement. Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 C in a cement kiln.
Portland pozzolana cement, portland slag cement, and portland fly ash cement are all made by adding active admixture and an appropriate amount of gypsum based on Portland cement clinker. They are similar in nature and scope of application, so they can be used interchangeably in most cases.
Portland cement manufacturing process can be divided into 6 steps raw material crushing, pre-homogenization, fine grinding, clinker production, cement grinding, cement packing, etc. In these processes, we need the assistance of different kinds of cement equipment, such as cement kilns, cement mills, and cement crushers.
