Raw meal grinding is a vital link in the cement raw material preparation process. After the cement raw material is crushed, it will be sent into the raw mill for further grinding until a certain degree of fineness is reached, and then enter the clinker calcination process. From the production experience of many cement plants, the selection of ...

Cement raw meal is the raw material for producing cement clinker, which is prepared in a certain proportion after crushing and grinding. After being calcined in a rotary kiln, the raw meal is turned into the clinker. Raw meal in the stackyard The composition and shape of the raw meal may vary according to different cement production methods.

A Norwegian cement plant producing about 1.3 million tons of cement per year was used as a case study. A mass and energy balance was made for the raw meal department, and process data available from the plant process database as well as manually measured gas flow rates were used to calculate the available heat.

The raw mill system for the new dry clinker production technology generally consists of a raw mill, a precalciner and a rotary kiln. During the mill-on mode, the raw materials are ground to raw meal in the raw mill, which is then sent to the precalciner after passing through the raw meal warehouse.
