How to Repair Liner Plate in Ball Mill
Domestic high manganese steel has been gradually replaced by alloy steel liner plate. With the application of alloy steel liner plate, it has become the market mainstream. Ball mill liner plate is used to protect the cylinder body. Many customers complain that liner plate’s life span is too short and the production cost is too high. With advanced technology in producing liner plate, KAIYUAN COMPANY can offer first-class quality and reasonable price to customers. Both casting steel ball and liner plate are with high wear resistance and strong corrosion. Due to the impact, grinding, sliding, rolling and bouncing by grinding media, liner plate will be wore. Liner plate shall be timely changed if it is seriously worn and there is no need to repair. Liner plate should be mended if there is less of wear resistance and a shortage. 1. Remove liner plate and clean the surface until bright metal is exposed. 2. Insert the graphite plug into the liner bolt holes to ensure the welding bolt hole is not small and fix the liner plate. 3. Place the awaiting mending liner plate on the platform with face upwards. 4. Surfacing electrode: such as TDMn (180) or tdcrmn (220), low hydrogen electrode 5. Clear up the work surface, clean welding slag and other debris and burrs lining around the etc. Manual arc welding is available and it is better to operated by skilled workers. 6. The program starts from surfacing welding steel surfacing layer and the built-up welding surfacing. Surfacing is divided into many narrow segments according to the order, surfacing. Finally, according to the liner shape of welding work surface plate of the original design (such as the ladder shaped, wavy liner), must be smooth, as much as possible to reduce the amount of dressing.
