Cement making production line

The cement production line chiefly comprises the following four processes: crushing and preblending course, homogenization of raw material preparation, preheating and decomposition, sintering of cement clinker, cement grinding packaging.

The cement production line process: During the process of the cement production, the cement making machine needs 3 tons of grinding materials at least (including all kinds of raw materials, fuel, clinker, mixture, plaster) to produce 1 tons of silicate. According to the statistics, the dry method to produce cement needs to consume the energy more than 60% that of the whole factory, with the raw materials grinding more than 30%, the coal grinding about 3%, the cement grinding about 40%. Therefore, reasonable choice of grinding equipment and process, the optimization of process parameters, correct operation and the controlling of operation system are significant to improve the quality and reduce the energy consumption.

The equipment that cement production line includes cement rotary kiln, cyclone preheater and grate cooler.

Cement rotary kiln is the principal equipment for calcining the cement clinker and it is broadly used in these industries like cement, metallurgy and chemistry etc.. This device is composed of the kiln body, supporting device, supporting device with a gear wheel, transmission, moving kiln head, sealing device for kiln tail, burning device etc. This kind of rotary kiln is with simple structure, reliable operation and easy to control the manufacturing process.

Grate cooler is quenching type cooler, for using the blower to blow cold air to quench the laminar clinker laid on the grid plate, making the clinker’s temperature strikingly drop from 1200℃ to 100℃ below. The cooled plenty of emissions are as the second wind except for those inletting ones.
