Cement Grinding Plant

The cement grinding plant mainly used in crushing and preheating of raw materials, and grinding and packaging of cement. And it is mainly applied to deal with industrial solid wastes like slag, coal ash, coal gangues, and so on. Therefore, it contributes great to the environment protection industry.

Our cement grinding plant has the features of simple technological process, easy operation, low investment, electricity saving, environmental friendliness, etc. And various admixtures can also be used in this plant.

Here in Jiangsu Pengfei Group Co., Ltd, one-stop service is available, including engineering design, construction, related equipment, assembly and debugging, technical service, and general contracting service. Besides, we have successfully finished many relevant engineering projects, like the construction of cement grinding plant with an annual output of 1-1.2 million tons, the building of cement grinding plant with 0.5-0.6 million tons' annual output, the construction of 0.2-0.3 million tons' annual output cement plant, and the building of plant with 0.1 million tons' annual output.

1,000,000Tons/Year Cement Grinding Plant:
In this 1,000,000t/y cement grinding plant, clinker and slag are ground separately. PFG120-50 rolling machine and Φ3.2m×13m cement mill are used in clinker ginding. Φ3.2m×13m ginding machine and high-efficiency powder separator are used in slag grinding.

This plant features are high quality, high productivity and low consumption.

Process Flow Design of 1,000,000Tons/Year Cement Grinding Plant:
1. Designing of Clinker Grinding Production Line
After gypsum, clinker and limestone are measured by the belt weigher, they will be mixed together in accordance with particular proportions, and then sent to the stable weighing warehouse. During this process, magnetic metals are removed by the iron remover from these materials. Then mixed materials will be sent into the rolling machine to be crushed. After crushed, they will be sent to the powder separator, in which coarse powder will be sent back to the griding mill while the fine one will be sent to the elevator for finished products. Finally, they will be sent to finished product storage. Meanwhile, dusty gas from the grinding mill will be purified by the environmental protection equipment before discharged into the atmosphere.

2. Design of Slag Grinding Production Line
Gypsum, dry slag and pulverized coal are measured by the belt weigher before mixed together according to particular proportions. Mixed materials will be sent to the mill for grinding, and during this process, iron remover is employed to remove magnetic metals in these materials. After grinded, fine powder will be sent to high-efficeint powder separator, while coarse powder will be sent back to the grinding mill. Finished cement will be collected by the air tank pulse bag filter, while the fine powder will be sent to the storage for finished products through an elevator. Dusty gases from the mill will be used as the first gas to enter into the powder concentrator, which is followed by fresh air. Finally, dusty gas will be purified by the air tank pulse bag filter before discharged into the atmosphere.

3. Design of Mixing Fine Slag and Powder Clinker
Besides the fineness of powder clinker and fine slag in the grinding production line, accurate measuring and even mixing also need to be paid much attention to. That's why we choose to use the screw measurer as the measuring device and the air slide as mixing device as well as conveying device.
