Characteristics and Working Principle of Limestone Ball Mill

timeMar 09,2021

Fly ash is the core raw material of limestone ball mill. Limestone is also one of the main raw materials for the production of aerated concrete. The main function of the lime ball mill is to cooperate with cement to provide the best calcium oxide so that it can interact with SiO2 and Al2O3 in siliceous materials under hydrothermal conditions. Whether it is fly ash or lime, it needs to be finely crushed. The lime ball mill is a good fine crusher. Lime ball mills are widely used in the production of cement, silicate products, new building materials, refractory materials, fertilizers and glass ceramics. It can be said that they are widely used. Therefore, the development of limestone has gradually increased in recent years. The competitiveness of limestone ball mills gradually increase.

Working Principle

The limestone ball mill is a horizontal cylindrical rotating device, divided into two bins, and the outside rotates along gears. The lime material that needs to be ground enters the first silo of the mill. This silo is equipped with a step liner and various specifications of grinding media.

When the equipment starts to operate, the materials and media inside the cylinder will be taken away by the cylinder liner and fall heavily under the action of centrifugal force and frictional force. When the gravity is greater than the centrifugal force, the materials and grinding media will leave the cylinder. The wall is projected to fall or roll down. Due to the impact force, the grinding medium will have a strong impact and grinding effect on the material, which will cause the material to be broken. The lime material that has been coarsely ground in one warehouse enters the second warehouse through a single-layer partition board. This warehouse is equipped with a flat liner and a steel ball grinding medium. The material is further ground here, and the feeding end is continuously fed to promote the feeding There is a material surface difference between the material and the material at the discharge end. The material surface difference causes the material to be forced to flow, and the finished product is discharged through the discharge grate.


1. The drive of the lime ball mill adopts rolling bearings instead of sliding bearings, the friction is greatly reduced, the starting is easy, and the energy saving is significant.

2. Its discharge end adopts a cone design, which not only increases the volume, but also forces the steel ball at the cone end to be classified. The closer to the outlet, the smaller the diameter of the steel ball, which increases the effect of repeated grinding so that the fineness of the material is further improved.

3. It adopts grooved ring-shaped liner, which increases the contact surface of ball ore, strengthens the grinding effect, and has the ability to lift the ore and reduces the power.

4. It adopts an integral frame, which is convenient for civil construction and equipment installation.

The main purpose of the lime ball mill:

Lime ball mills are used to grind various ores and other materials, and are widely used in various sectors of the national economy such as mineral processing, construction and chemical industry.

The lime ball mill has attracted attention due to its wide application range and strong grinding ability. There are many manufacturers selling this equipment on the market. At present, there are many manufacturers selling this device on the market. You can shop around, and after comparing prices and performance, choose one with high quality and low price.
