Cement manufacturing is a complex and energy-intensive process. A key stage in this process is the conversion of ground raw materials (CaCO 3, clay and/or shale) into clinker (synthetic cementitious minerals) in the kiln. A typical operation uses kiln exhaust gases to preheat the raw materials before they enter the kiln. Further

May 04, 2020 Cement is the combination of calcium carbonate, silica, alumina and ferrous oxide, which are naturally found in limestone rock, chalk, shale and/or clay. During the cement production process, these minerals are fused together by heating them to just under their melting point, forming a cement clinker between 3 to 20 mm in diameter.

The 2500t / d cement clinker production line adopts a new dry process, with an annual output of 775,000 tons of cement clinker and a total cement output of 1.05 million tons / year. A cement production line and auxiliary facilities from limestone crushing to cement packaging are constructed.

The clinker is then cooled and ground to a fine powder in a tube or ball mill. A ball mill is a rotating drum filled with steel balls of different sizes (depending on the desired fineness of the cement) that crush and grind the clinker. Gypsum is added during the grinding process to provide means for controlling the setting of the cement.

Under the process, the raw material can be fully mixed with the hot gas discharged from the kiln, increase the contact area of the gas material, fast heat transfer speed, and high heat exchange efficiency, thereby improving the production efficiency of the rotary kiln system and reducing the heat consumption of the clinker.

In portland cement manufacturing process, the quality of cement clinker directly affects the quality of the finished product cement.. The following are several important factors affecting the cement clinker quality. In the process of clinker production, strict control of these factors can ensure the production of high-quality, high-yield clinker.

The overall process of conversion from raw meal to clinker being endothermic demands a theoretical heat of about 380-420 kcal/kg-clinker.
