The technics of cement production process

In the technics of cement production process, People usually choose limestones and clays as the main raw materials, crushing, concocting, grinding them into cement raw meal, feeding them into cement kiln. After being calcined maturity, adding appropriate amount of gypsum (sometimes mixing the mixed material or admixture) then being grinded, and the cements form.

a) Crushing and pre-homogenization

In the first phase of cement production, most of the materials should be crushed, such as limestones, clays, iron ores, coals etc. Especially the limestones are the largest and high-hard materials. Therefore the limestone crushing is very important in the cement production.

In the phase, the recommended machines are jaw crusher, impact crusher and cone crusher. Sometimes the construction wastes are used as the raw materials, and then a mobile crusher may be a good choice.

b) The prepare and homogenization of cement raw materials

In this process, the available grinding mills include Ball mill, Raymond mill and other roller mill. But usually the processing capacity of the Raymond mill can't meet the big demand of the clients. We know the amount of the rollers determines the processing capacity of grinding mills, a new roller mill with 6 rollers has been the popular one and achieves high reputation from the users, which is called Super Pressure Trapezium Mill. Its capacity can be up to 20 tons per hour.

c) Pre-decomposition and the burning of cement clinker

d) Cement grinding

Cement grinding is the final process in cement manufacturing, which cost the most electric power. Its main function is to grind cement clinkers into the required size. Ball mill can also be used in this process.
