Application Case Of Alumina Wear Resistant Ceramic Liner in The Lining Of Ball Mill

As an important equipment for refining solid materials, ball mills are widely used in construction, cement, metallurgy, chemical, ceramics, electric power, medicine and national defense industries. When the ball mill is working, the materials are passed through the feeding device through the hollow shaft spiral. It evenly enters the mill. The mill is equipped with different specifications of grinding media. The centrifugal force generated by the rotation of the cylinder will bring the grinding ball to a certain height and then fall, which will give a heavy blow and grinding effect to the material.

The alumina wear resistant ceramic liner can be used as the inner liner of the ball mill. Its main component is alumina, which has high purity, which greatly reduces the pollution caused to grinding materials. It has good wear resistance and is 266 times that of manganese steel. It effectively prolongs the service life of the equipment. It has high hardness, high density and abrasion. Low, good regularity, corrosion resistance, etc., can effectively improve grinding efficiency, reduce grinding costs, and reduce product pollution.

The wear of the lining of the mill not only depends on the characteristics of the wear resistant ceramic liner itself, but also is proportional to the pressure of the ball milling medium on the wear resistant ceramic liner and the relative movement rate between the two. With the increase of the size of the ball mill, the inner diameter of the grinding cylinder increases, the pressure of the ball stone on the wear resistant ceramic liner and the linear velocity of the ball and the wear resistant ceramic liner increase, resulting in increased wear of the wear resistant ceramic liner. Therefore, a thicker wear resistant ceramic liner should be used for larger ball mills. Generally, if the diameter of the ball mill exceeds 1.8m, it is recommended to use a 60mm thick wear resistant ceramic liner.

 The wear resistant ceramic liner can reach ninth grade due to its Mohs hardness, so it can grind quartz, glass, ceramic glaze, ore, enamel, alumina, etc. with high efficiency. The grinding slurry is fine and high in quality. And because of its high wear resistance, it does not need to be replaced frequently, which greatly saves the company's time and raw material costs.
