Cement Mill

Introduction of cement mill

Cement mill is also called cement ball mill, which is mainly used for grinding cement clinker in the cement production process. It is one of the important cement equipment.

Cement mill has the advantages of the small occupied area, stable running, convenient operation and other advantages, so as to achieve the high yield and high fineness, which has provided a strong guarantee for the production of high quality cement. According to the different needs of cement, it can adopt the edge transmission or center transmission, which has a flexible configuration.

Cement miller is widely used for cement, silicate products, new building materials, refractory materials, fertilizer, black and non-ferrous metal and glass ceramics. The cement mill is available in both wet process grinding and dry process grinding.

Features of cement mill

1. High grinding efficiency. The material bed pressure crushing principle is adopted for the rolling, shearing and impacting of materials in the mill. The airflow inside the mill can bring out the ground materials to avoid over-grinding.

2. Large feed granularity. It usually takes up 5% diameter of the grinding roller. Cement mill has superior performance, large output, and high operation rate.

3. Strong adaptability to various materials. It can be used for grinding various raw materials such as limestone, sandstone, coal, cement clinker, hopper, blast furnace slag etc.

4. Excellent overall airtight, less dust, low noise and superior working conditions.

5. The fast quality control and flexible adjustment of products make it easy to realize intelligent and automatic operations.

6. The turning gearwheel of cement mill adopts casting hobbling process and the drum is equipped with wear-resistant liner, which has good wear-resistance.

Working principle of cement mill

This machine is a horizontal type cylinder rotary device and outside the cylinder, there is drive gear which drives the cylinder to rotate during the working process. Materials spirally and evenly go into the first cabin of the grinding machine through the feeding hollow shaft from the feeding device, and inside the first cabin, there are ladder lining boards or ripple lining board in which there are many steel balls with different specifications.

The cylinder rotates and produces eccentric force to bring the steel balls to a certain height, and then the steel balls will fall down to impact and grind the materials. After being coarsely ground in the first cabin, the materials will go through the single-layer partition board and into the secondary cabin in which there are scale board embedded and steel balls in the warehouse. The materials will be further crushed in this warehouse. The powder will be discharged by the uploading plank. Then, the grinding work will be finished.
