Cement ball mill

MoleDive, a world-leading crusher manufacturer, assists clients in completing high-intensity crushing operations

The ball mill is the key equipment for crushing the material after it is broken. Bailing energy saving ball mill adopts double row aligning bearing, energy consumption is reduced by 30%, and material processing capacity is increased by 15%-20%; The main bearing is lubricated by grease, convenient and clean, free from heavy metal pollution.

grinding all kinds of ore and other materials. Widely used in cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal mineral processing and glass ceramics and other production industries.

MoleDive Cement ball mill Guide

1.what is cement ball mill?

Cement clinker and gypsum are fed into the first bin of the mill barrel through the cement ball mill feeding device, in which the material is smashed to a certain particle size by the abrasive body with a larger average ball diameter, and then the diameter silo plate enters the second bin. The second bin is equipped with a grinding body with a smaller average ball diameter, and the material is further ground by the grinding body in this bin. The ground material passes through the discharge grate, is removed from the lower outlet of the discharge device, and then after sorting by the matching powder separator, the coarse material is re-fed into the mill to continue grinding, and the qualified fine powder is the finished cement. The cement ball mill is mainly composed of a feeding device, a sliding shoe bearing, a rotating part, a discharging device and a sliding shoe bearing lubrication and a central transmission device (including a main reducer and its lubrication device, a main motor, a slow drive device, etc.).

2. how does a cement ball mill work?

Cement ball mill is composed of a horizontal cylinder, inlet and outlet hollow shaft and grinding parts, the cylinder is a long cylinder, the cylinder is equipped with a grinding body, the cylinder is made of steel plate, there is a steel lining plate and the cylinder is fixed, the grinding body is generally a steel ball, and is loaded into the cylinder according to different diameters and a certain proportion, the grinding body can also be used steel section.

According to the particle size of the grinding material is selected, the material is loaded into the cylinder by the hollow shaft of the feed end of the ball mill. When the ball mill cylinder rotates, the grinding body is attached to the lining plate of the cylinder due to the action of inertia and centrifugal force, and the action of friction force, so that it is taken 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 acts like a projectile and shatters the material inside the cylinder. The material is uniformly fed into a bin of the mill by the feeding device through the feeding hollow shaft. There is a stepped liner or corrugated liner in the bin, which is loaded with steel balls of various specifications. The centrifugal force generated by the rotation of the cylinder will bring the steel ball to a certain height and then fall, which will have a heavy impact and grinding effect on the material. After the material is coarse ground in the first bin, it enters the second bin through the single compartment plate, which is inlaid with a flat liner plate and contains a steel ball to further grind the material. The powder is discharged through the discharge grate to complete the grinding operation.

3. how ball mill work in cement industry

Cement ball mill cylinder in the process of rotation, the grinding body also has the phenomenon of sliding, in the sliding process to the material with grinding effect, in order to use the grinding effect, the material particle size of the general twenty mesh grinding fine, the grinding body cylinder is divided into two sections with silo plate, that is, become a double bin, the material into a bin when the steel ball crushed, the material into the second bin, The steel section grinds the material, and the material that is fine and qualified is discharged from the hollow shaft at the discharge end. When the material with small particles is grinded, such as sand No. 2 slag and coarse fly ash, the mill barrel body can be made into a single barrel mill without a partition, and the grinding body can also be made of steel section.

The raw material is ground through a hollow journal into a hollow cylinder containing grinding media of various diameters (steel balls, steel rods or gravel, etc.). When the cylinder rotates around the horizontal axis at a certain speed, the medium and raw materials installed in the cylinder under the action of centrifugal force and friction force, with the cylinder reaches a certain height, when its own gravity is greater than the centrifugal force, it is removed from the inner wall of the cylinder to throw down or roll down, and the ore is crushed due to the impact force. At the same time, in the process of mill rotation, the sliding movement between the grinding medium also produces grinding effect on the raw material. The ground material is discharged through the neck.
