1.1 Currently, the production capacity of cement ball mills in China is relatively low and energy consumption is high

At present, cement ball mills in China generally use small and medium-sized ball mills with diameters less than 3mm, which have relatively low production and significant energy consumption. With the acceleration of urbanization, the demand for cement continues to rise. In order to meet market demand, some enterprises have begun to transform traditional production models using clinker production processes, especially upgrading shaft kiln cement plants. However, due to the small diameter and limited quantity of powder mills, some enterprises have failed to effectively manage them, resulting in unstable quality of cement production. Practice has shown that this production process is relatively backward, with high energy consumption and overall low work efficiency.

1.2 Insufficient quality stability of cement products

The quality of cement products has strict requirements for their fineness. China has clear standards for various parameters of cement products, which are the main basis for ensuring the fineness of cement. However, some production enterprises, when innovating cement production processes, arbitrarily draw on advanced foreign technologies. Due to the limitations of domestic production conditions, it is difficult to meet the requirements for fineness, which affects the quality of the products.

1.3 The problem of coarse cement particles

Coarse cement particles not only lead to waste of raw materials and increase production costs, but also reduce the strength of cement products. Therefore, it is necessary to reduce the fineness of the finished cement to improve its strength, while reducing the amount of clinker added to ensure the strength of the factory cement. Reducing the ratio of clinker while ensuring the quality of cement can effectively improve the quality of cement and reduce production costs.
