Foreign cement enterprises are constantly using high-tech production, vertical mill has long been popular abroad. Driven by scientific and technological progress and the development of The Times, China's traditional cement production line manufacturing mode is undergoing profound changes, cost saving, the pursuit of high yield and high efficiency, cement production line to achieve green and environmental protection are the needs of cement production in this era. Production and management of grinding machine equipment for many years committed to improve the performance of equipment and also to protect the environment, vertical grinding machine production has been to achieve the goal of cement pollution-free production.

The products are processed into powder and then further processed into various high-value-added products, which are widely used in metallurgical, chemical, building materials and other industries. At present, domestic grinding equipment is mainly used for ramon mill, ball mill, etc., among which ramon mill is more commonly used. However, these traditional grinding equipment have some disadvantages such as high production cost, small production capacity and serious pollution. Therefore, a kind of vertical mill with large output, low cost, safe use, clean and environmental protection emerges at the right moment, which is widely used in mineral processing of different industries with obvious effect.

The traditional pendulum mill and bar mill is a kind of grinding equipment in the form of "ring-roll" grinding combined with airflow screening and pneumatic conveying. The following is a list of the limitations of the traditional mill grinding performance:

1. Single machine has low capacity and high cost. Some ramon mills have low production capacity and high overall cost, which cannot meet the requirements of large-scale production and affect the economic benefits of enterprises.

2. Large space. Due to the low output of traditional ramon mill, the number of equipment used is large and the site occupied is large under certain output demand.

3. Poor environmental conditions. The traditional grinding equipment has great noise and serious dust pollution, which affects the industrial environment.

4. Equipment maintenance is difficult. Ramon mill in the maintenance of manual operation is difficult, inconvenient.

5. Low quality of finished products. The whiteness of powder produced by ball mill is low, which will greatly affect the quality of finished products.

In recent years, vertical mill has performed well in the market. The performance advantages of vertical mill can be summarized as follows:

1. Large single machine output, suitable for large-scale production. The vertical grinding capacity is large, the production time can be up to 100 tons, to meet the large-scale production of enterprises.

2. Green and clean process. The vertical mill process has less pollution, less influence on whiteness and low iron content, which can effectively improve product quality.

3. Granularity control. Vertical mill is convenient for fineness control, particle size cutting and concentrated distribution, which can meet customers' requirements for different products.

4. Good quality of finished products. Vertical mill has the functions of automatic slag discharge and sand discharge, which can discharge semi-burnt products in lime, improve the content of calcium oxide and optimize the quality of finished powder.

5. Low noise and less dust. Vertical mill adopts material bed grinding principle, no direct contact between grinding roller and grinding disc, smooth operation, low noise. In addition, vertical grinding is a negative pressure dust suction production, effectively avoid dust in the grinding process.

6. Intelligent control. The vertical mill adopts PLC intelligent control system, which can realize unmanned operation and grasp the operation data of the equipment through the mobile phone terminal.

7. Low maintenance cost. The direct contact between the grinding parts is less, the damage rate is low, the wear-resistant parts have a high service life, and the maintenance cost is low.
