Cement plant is also called cement manufacturing plant, which is a series of cement production equipment. It is mainly made up of crushing and pre homogenization, raw material preparation, homogenization of raw materials, preheating and decomposition, cement clinker burning, cement grinding as well as packaging process, which is the more complicated production process. The main equipment of cement production line includes cement rotary kiln and cyclone pre-heater, grate cooler, etc.
1 Crushing during the process of producing the cement, the majority of materials are needed to be crushed, such as the limestone, clay, iron ore, coal, etc.
2Pre-homogenization of raw materials pre-homogenization technology is to use scientific material piling technology to realize the preliminary homogenizing of raw materials and to make the materials stockyard have the combined function of storage and homogenizing during the process of storing and feeding of raw materials.
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.
During the new cement production process, the stability of raw material component is in the premise of firing system. The homogenization system plays an important role in the stability of putting the raw material into the pit at the last line.
The preheating and parts of decomposition of raw materials are completed by the pre-heater to replace part of the rotary kiln function, shorten the length of the kiln and make the gas with accumulation state in the kiln conduct the heat transfer process. Therefore, it can be moved to the inner suspension pre-heater condition, which can mix the gas in the kiln completely, add the touching area, quicken the heat transfer and improve the efficiency of heat exchange to increase the productivity ratio and reduce the energy consumption.
Cement grinding is the last and the most power-consuming process. Its main function is to grind cement clinker and gelling agent, performance adjustment material, etc. to appropriate particle size represented by fineness, specific surface area to form certain granular level, increase the water area and accelerate the hydration rate of cement paste, so as to meet the condensation and hardening requirements.

Mar 01, 1993nbsp018332Cement production is one of the most energy intensive of all industrial manufacturing processes. Including direct fuel use for mining and transporting raw materials, cement production takes about six million Btus for every ton of cement Table 2. The average fuel mix for cement production in the United States is shown in Table 3.
