In the cement production process, the main functions of grinding equipment are grinding cement raw materials, cement clinker and coal for calcination. As one of the cement equipment suppliers in China, AGICO offers different types of cement mill which can be used as raw mill, cement grinding mill and coal mill. As the main cement equipment, they are respectively used in different stages of cement manufacturing.
Raw mill is the grinding equipment applied in the raw material preparation process. In the wet process of cement production, raw materials should be ground into raw slurry with a water content of 30% – 40%. While in the dry process of cement production, they will be ground into dry powder in cement raw mill.
- Raw mill in the dry process: cement ball mill, cement vertical mill, Raymond mill, etc.
- Raw mill in the wet process: rod mill, etc.
Coal mill is the main equipment in the pulverized coal preparation process. Because calcining top-grade cement clinker requires a stable supply of coal powder as the fuel of cement kiln, and more than 85% of pulverized coal should be finer than 200 mesh, water content less than 2%, and calorific value more than 6000Kcal/kg, therefore the pulverized coal preparation system is one of the important links to ensure cement production.
The coal mill commonly used in cement plants includes air swept coal mill, coal vertical mill, Raymond mill, etc.
Cement grinding mill is usually used in the clinker grinding process. It is the final stage in cement production which will directly affect the cement product quality, output and benefits. Clinker particles, gypsum, and other materials in cement grinding machine will be ground together into fine powder to match the fineness of the finished product.
The cement grinding mill in a cement plant mainly includes cement vertical mill, cement ball mill, ultra fine grinding mill, cement roller press, etc. They are suitable for both wet process and dry process.
AGICO offers EPC cement projects and different kinds of equipment needed for cement plant, such as a series of cement mills: cement ball mill, rod mill, cement vertical mill, ultra fine grinding mill, cement roller press, Raymond mill, and air swept coal mill.
