 Portlant Cement Process Routing

Cement Grinding Unit

We provide the whole service of design manufacture and installation, EPC project or parts equipment. We design and manufacture devices for new type dry method cement production line, which capacity from 300t/d to 2000t/d clinker. And we can also assist the client in transacting purchaser`s credit or Chinese government`s credit while exporting.

Rotary kiln is the main equipment for sintering cement clinker. The rotary kilns produced by our company can be divided into dry process and wet process. They can also be used for chemical industry, metallurgy industry and etc. Throught technical renovations, the rotary kiln sintering system equipment made by our company has adopted high measuring precession plunger pump, variable speed adjusted valve, contact graphite block air seal and other national advanced technologies. In order to raise up automation degree, indurstrial TV has been used at the kiln head for monitoring of kiln, analog fluorescent screen has been used for display of process flow; Infrared scanning system has been adopted for sintering zone to directly reflect the burning conditions on the computer. With the use of these new technologies, it is directly in vision, convienent in operation and reliable in use. Therefore, the rmalcondition can be raised. Compared to been raised 3-5% up, production has been increased 5-10% and heat consumption has been reduced 15% down.

Rotary kiln belongs to building material equipment, which can be divided into cement kiln, metallurgy chemical kiln and lime kiln according to different materials.

Cement kiln is used for making of cement clinker and there are dry and wet methods to make cement. metallurgy chemical kiln is used for magnetic roasting of iron ore and oxidizing roasting of chrome and nickel in the steel factory; baking high-alumina mine in the refractory material factory; baking chamotte and alumina in the aluminium factory and baking chrome ore and chrome powder in the chemical plant.

Lime kiln is used for baking active lime and dolomite in the steel factory and ferroalloy factory.

 Process of cement production line: 

1.Raw Materials 
The main raw materials used in the cement manufacturing process are limestone, sand, shale, clay, and iron ore. The main material, limestone, is usually mined on site while the other minor materials may be mined either on site or in nearby quarries. Another source of raw materials is industrial by-products. The use of by-product materials to replace natural raw materials is a key element in achieving sustainable development.
 
2.Raw Material Preparation 
Mining of limestone requires the use of drilling and blasting techniques. The blasting techniques use the latest technology to insure vibration, dust, and noise emissions are kept at a minimum. Blasting produces materials in a wide range of sizes from approximately 1.5 meters in diameter to small particles less than a few millimeters in diameter. 
Material is loaded at the blasting face into trucks for transportation to the crushing plant. Through a series of crushers and screens, the limestone is reduced to a size less than 100 mm and stored until required. 
Depending on size, the minor materials (sand, shale, clay, and iron ore) may or may not be crushed before being stored in separate areas until required.

3. Crushing and Pre-homogenization.
Crushing. During producing concrete, most of the raw materials must be first crushed before being used to make concrete. Among these raw materials which include lime stone, clay, iron ore and coal, etc. the lime stone is of the greatest usage to make concrete. With comparatively larger particles and higher hardness, crushing the lime stone to required fineness after mining is of relatively important consequence among crushing all those raw materials. There are many crushers used in crushing these raw materials, such as jaw crusher, impact crusher, cone crusher and vertical shaft impact crusher, etc. According to the raw materials' different particles and hardness, there are several suitable crushers which can be used in the crushing.
Pre-homogenization of raw materials.

4. Raw material Homogenization.
In the process of new dry concrete production, the stability of pit entry clinker raw material component is the premise of the whole system. Raw material homogenization system plays very important role in the stability of pit entry clinker raw material component.

5. pre-heater and calciner

6. The burning of concrete clinker.

7. Grinding
Grinding is the last process of cement produce and also is the most current consuming working procedure. Cement clinker get grinded into the right size. The smaller the particle size is, the better the final cement is.It's important to choose suitable grinding machine.8. Concrete Packaging.
