Cement mill

product Introduction

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.

The output of cement mill is 21~155 t/h, and the specific surface area of cement is 3300~3800 cm ² /g. Cement mill has the advantages of 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 flexible configuration.

Working Principle

According to the particle size of the grinding material, the material is loaded into the cylinder by the hollow shaft of the feeding end of the mill. When the ball mill rotates in a simplified manner, the grinding body acts as a frictional force due to inertia and centrifugal force, so that it is placed near the cylinder liner. It is carried away by the cylinder. When it is brought to a certain height, it is thrown off due to its own gravity. The falling abrasive body crushes the material in the cylinder like a projectile. The material is uniformly fed into the mill bin by the feeding device through the hollow shaft of the feeding material. The bin has a step liner or a corrugated liner, and the steel ball of different specifications is built therein. The cylinder rotates to generate centrifugal force, and the steel ball is brought to a certain height and then falls. , causing heavy impact and grinding on the material. After the material has been coarsely ground, it enters the warehouse through a single-layer compartment board. The warehouse is equipped with a flat lining plate with steel balls inside to further grind the material. The powder is discharged through the discharge raft to complete the grinding operation.
