Construction Technology of Wear-Resistant Ceramic Lining Brick Lined in Ball Mill
1. Firstly, remove the dirt, cement residue, rust, welding slag, dust and oil on the surface of the ball mill. The smooth surface can be roughened to improve the bonding effect.
2. The ceramic lining board of the ball mill is generally bonded with white cement or wear-resistant ceramic structural glue. The construction starts from the end face of the ball mill. The end face is all installed together with straight bricks and straight half bricks. In the ball mill, the bricks are closely bonded to each other. Every time a few lining bricks are installed, they should be tapped lightly with a rubber hammer or wooden hammer, so that the adhesive can be evenly spread between bricks and bricks, and between bricks and the cylinder wall. To ensure the bonding quality, strictly control the gap between bricks to be less than 1.5mm.
3. When installing the cylinder, calculate the number of straight bricks and oblique bricks that need to be used, and install them alternately in proportion. It is necessary to ensure that the wear-resistant ceramic lining bricks are tightly bonded to the inner wall of the cylinder, and the installed ceramic surface forms a smooth connection. Seal it tightly with cement to ensure the bonding strength, so that the ceramics and the equipment are closely integrated, which can prolong the service life of the wear-resistant ceramics and reduce the maintenance of the ball mill equipment.
