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.
(2)Pre-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.
After the preheating and decomposition in the pre-heater of the raw materials, the next process is to fire the clinker in the rotary kiln. The carbonate in the rotary kiln is further decomposed rapidly and it will cause a series of solid phase reaction, which will generate cement clinker minerals. With the increase of material temperature, the mineral will become liquid and they will be dissolved in the liquid phase and reaction to generate a large amount of clinker. After burning, the temperature of clinker begins to decrease. Finally the cement clinker cooling machine will convey the high temperature clinker discharged by rotary kiln to the withstand temperature of downstream transport, storage and cement mill. At the same time, the sensible heat and recovery of high temperature clinker will improve the heat efficiency and the quality of clinker.
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.

1. The cement mill process begins when limestone, the basic raw material used to make cement, is transported by rail to the Edmonton plant from the Cadomin limestone quarry 220 kilometers west of Edmonton.
2. The limestone is combined with clay, ground in a crusher and fed into the additive silos. Sand, iron and bottom ash are then combined with the limestone and clay in a carefully controlled mixture which is ground into a fine powder in a 2000 hp roller mill.
3. Next, the fine powder is heated as it passes through the Pre-Heater Tower into a large kiln, which is over half the length of a football field and 4.2 meters in diameter. In the kiln, the powder is heated to 1500 degrees Celsius. This creates a new product, called clinker, which resembles pellets about the size of marbles.
4. The clinker is combined with small amounts of gypsum production process, limestone and finely ground in a finishing mill. The mill is a large revolving cylinder containing 250 tonnes of steel balls that is driven by a 4000 hp motor. The finished cement is ground so fine that it can pass through a sieve that will hold water.
5. The dry cement process consists of many simultaneous and continuous operations using some of the largest moving machinery in manufacturing. Over 5000 sensors and 50 computers allow the entire operation to be controlled by a single operator from a central control room.
Cement plant is usually located closely either to hot spots in the market or to areas with sufficient quantities of raw materials. The aim is to keep transportation costs low. Basic constituents for cement (limestone and clay) are taken from quarries in these areas.
Cement ball mill is also named natural material mill, material grinding mill and clinker mill, is key equipment for grinding following the concrete crush process, which can be trusted in the manufacture industries, including cement, silicate, new building materials, refractory material, fertilizer, ferrous metal, nonferrous steel and glass ceramics, etc. Cement ball mill may be used for the dry and wet grinding for all kinds of ores as well as other grind-able materials. Based on different materials and discharging methods, there are dried up cement ball mills and wet ball mills for option.
