Brief introduction & Application:

Alumina oxide lining is a highly versatile material that finds extensive use in a wide range of industries due to its exceptional properties. Alumina oxide lining is made of high purity alumina oxide powder. It has superior hardness and wear resistance, making it an ideal solution for abrasion and impact wear applications.

One of the most significant application fields of alumina oxide lining is mining. In the mining industry, heavy-duty equipment such as chutes, hoppers, and conveyors are continually subjected to wear and tear by abrasive materials. The use of alumina oxide lining in such applications can significantly increase the lifespan of the equipment, reducing repair costs while ensuring smooth and efficient operations.

Alumina oxide lining is also widely used in the chemical industry, where aggressive and corrosive chemicals are handled. The material's exceptional chemical stability and resistance to corrosion make it an ideal choice for lining tanks, pipes, and other equipment used in chemical processing. Furthermore, the high wear resistance of the lining is crucial in ensuring that the equipment remains operational even when subjected to harsh chemicals.

Installation guidence of 92% alumina oxide lining bricks

1.Ball mill preparation: Any rust and oil stains on the inner surface of the ball mill should be cleaned, and the smooth surface should be roughened to improve the bonding effect.

2. The installation of lining bricks starts from the end face of the ball mill. The end faces are all installed with straight bricks and straight half bricks. On the joints of the two bricks below, the upper and lower rows of bricks must be installed with staggered joints. Every time a few lining bricks are installed, lightly tap with a rubber hammer or mallet, so that the adhesive is evenly spread between bricks and bricks, between bricks and the wall, to ensure the quality of bonding, and strictly control the gap between bricks The gap should be less than 1.5mm.

3. After installing the two ends, start to install the cylinder, calculate the number of rows of straight bricks and oblique bricks according to the amount of lining bricks in the cylinder, and install them alternately in proportion to the number of straight and oblique rows calculated in the second step, so as to ensure that the bottom of the lining bricks is tight Attached to the inner wall of the cylinder, the inner diameter of the lining bricks after laying should be smoothly connected, and each row along the length direction should use straight bricks or inclined bricks of the same specification. The joints of the two rows of bricks are staggered, and if the straight bricks cannot enter the last row, install thinner bricks and seal the gaps with cement.
