Brief introduction & Application:

Alumina lining bricks are predominantly used to protect the inner surface of ball mills from wear and tear. These bricks are made from high-quality alumina powder, which works exceptionally well in resisting abrasion and wear.

Ball mills are used extensively in various industries for grinding and crushing different materials. However, the frictional forces generated during this process can cause significant wear and tear to the inner surface of the mills. This is where the use of alumina lining bricks comes into play.


  • Alumina lining bricks are incredibly durable and resistant to abrasion. They are able to withstand the harsh conditions that are present in the ball mills, and they can significantly prolong the lifespan of these machines.

  • Additionally, the use of alumina lining bricks can also increase the efficiency of ball mills since it reduces the amount of energy required for grinding materials.

  • Furthermore, alumina lining bricks are relatively easy to install and maintain. They are also available in different shapes and sizes, allowing for easy customization to suit the specific requirements of the ball mills.


Overall, the use of alumina lining bricks for ball mills is a highly beneficial practice that can protect the inner surface of the mills and increase their efficiency. With their exceptional durability and resistance to abrasion, these bricks are an excellent investment for any industry that uses ball mills regularly.

Application fields as below:

  • Ceramics, mines and other grinding equipment lining

  • Material transfer equipment,

  • Inside and outside surface of powder separating equipment on iron and steel works

  • Thermal and power plants

  • Coals and cements industries,etc.

Product feature details:

Ceramic lining bricks are specially designed for protecting machine, to protect against wear, corrosion, and thermal shock.

  • First and foremost, ceramic lining bricks are extremely durable and long-lasting. This means that they can provide superior protection to your equipment and extend its lifespan, saving you time and money in the long run. The use life time of ceramic alumina lining brick is 3~5 or more than 5 years.

  • Alumina content of 92%, high purity, few pollution for grinding materials

  • In addition to their durability, ceramic lining bricks are also highly resistant to abrasion and impact. They can stand up to heavy use without cracking or chipping, ensuring that they maintain their protective properties even under the most demanding conditions. This makes them ideal for use in applications like mining, cement production, and other heavy industries where safety and durability are critical.

  • Another key feature of ceramic lining bricks is their thermal shock resistance. This means that they can withstand sudden changes in temperature without cracking or breaking. This is particularly important in high-temperature applications, where the sudden cooling or heating of equipment can cause damage or failure.

How to install 92% alumina lining bricks?

installation of alumina lining

Ceramic alumina lining bricks are used for ball mill installation. The lower wear rate and stronger impact resistance will increase the service life of the ball mill.

  • Before installing, remove all the remaining pieces of the previously installed bricks and cement from the internal surface of ball mill. Roughen smooth surface and fix damaged iron shell with electric welding tool.

  • The installation gap should be within 1mm, using 425# white cement and 107# glue as combining glue.

  • Installation begins from side walls. Side wall will be installed with rectangle bricks totally. Then come to the cylinder installation. Use rectangle bricks and ladder type bricks in pairs. One rectangle brick following with one ladder type brick to ensure the bricks stick to the inner wall of ball mill closely. Until the last bit, if the regular size of bricks can not be fit in, use thin blocks. After finishing installation, clean up the surface.

  • To ensure the cement perform the maximum cohesion and intensity, spry water on the surface in the first two days. Then fill up the ball mill with water for 10 days.
