The cement production line is cement plant construction project which is composed of a series of supporting equipment whose function is producing cement.
Most of raw materials should be crushed, such as limestone, clay, iron ore and so on. The limestone is the main material used in cement production, after mining, the limestone has bigger granularity and high hardness, so the crushing of the limestone occupies an important place in raw material crushing in the cement factory.We can offer：
This system includes raw material grinding system and cement grinding system, of which cement grinding system is the final process of cement manufacturing and is the most power-hungry process, so selecting proper equipment is the key point to save cost and reduce energy consumption.
We can offer：
Ball mill: advantages: cheap price, using in all over the world, easy operation, convenient maintenance.more >>
Vertical mill: advantages: environmental protection and energy saving, low area occupying, low energy consumption, intelligent control.more >>
After finish the processes of preheating and pre-decomposition, the raw materials enter into the rotary kiln for calcination. In the rotary kiln, the carbonate is further quickly decomposed and starts a series of solid-phase reaction and generates the equal mineral in the cement clinker, and finally, the cooler cools the high-temperature clinker discharged from the rotary kiln to the temperature which can be bore by downstream conveying system, storage depot and cement mill. At the same time the sensible heat of the high-temperature clinker is recycled to improve the heat efficiency of the system and the quality of the clinker.We can offer：
The cement packing machine is a kind of weighting equipment whose functions are sub-packaging the cement and controlling the the weight of a bag of cement to be qualified. Besides it can also be used for filling of other powdery and granular materials with good flowing property.
In the process of cement manufacturing, it needs coal, heavy oil or other fuel as heat source, so the manufacturing of pulverized coal becomes an important link. The coal mill manufactured by CHAENG is suitable for grinding soft coal and other materials with medium hardness and used for the pressurized direct pulverizing coal system of burning soft coal. The coal mill not only possesses the advantages of low power consumption, simple coal pulverizing system, small noise and reliable running, but also possesses unique advantages of wide range of material application and good applicability both in high and low load.We can offer：

Cement grinding plant: simpleness, small investment, high profit
Build cement grinding plant near the cement sales market in the large and middle-sized cities. Most of the cement admixtures are from industrial residue in the city, and the cement grinding plant can vastly digest the industrial residue such as slag, coal ash, furnace slag, coal gangue and so on near the city and is a green and environmental industry.
The technological process adopted by the cement grinding plant is simple, the operation is easy and the investment of process and equipment is small, and the plant is power-saving and environmental and has the advantage of allowing to mix admixtures.
Representative projects of CHAENG
