How Does A Raw Mill Work In A Cement Plant.jpg

 

The raw mill of a cement plant prepares raw materials into raw materials that meet the requirements through steps such as crushing, mixing, grading (and possibly drying and sorting). In this process, the impact and rolling of steel balls (or grinding rollers) are the key to achieving raw material crushing and mixing. At the same time, the use of classifiers and powder selectors ensures the fineness and quality of raw materials. With the development of technology, the equipment and processes of raw mills are also constantly improved and optimized to improve production efficiency and product quality.

 
1. Crushing: The raw materials enter the cylinder (or grinding disc) of the raw mill from the feed inlet and are further crushed by the impact and rolling of the steel balls (or grinding rollers) in the cylinder. In addition, the grinding body also slides and rolls, so that the grinding body, lining plate, and material are crushed and ground.
 
2. Mixing: In the raw mill, the mixing and stirring of raw materials are achieved by the rotation of the cylinder and the impact and rolling of steel balls. This allows the raw materials to be evenly mixed and gradually reach the required fineness.
 
The crushed raw materials are mixed together to form a mixture called abrasive. At the same time, larger particles will be screened out by a classifier (such as a powder selector) and returned to the raw mill for further crushing, while finer particles enter the next process. This step ensures that the fineness of the raw material meets the requirements.
 
The raw mill of a cement plant is an important equipment in the cement production process, which is mainly responsible for crushing, mixing, and grinding raw materials (such as limestone and clay) into raw materials of a certain fineness.
