900*2200 Ball Mill Coupling Gear Lining Bucket Screw Accessories

The functions of the ball mill lining plate are: to lift the grinding media balls and segments, to play a grinding role and to protect the grinding cylinder. The lining plate is used to protect the cylinder from direct impact and friction between the grinding body and the material. At the same time, different forms of lining plates can also be used to adjust the movement state of the grinding body to enhance the crushing effect of the grinding body on the material. It helps to improve the grinding efficiency of the mill, increase output and reduce metal consumption.
For different materials to be ground, the ball mill linings selected are also different. The main considerations in selecting various lining plates are the lifting effect on the grinding media and the running trajectory of the media.
Lining materials include chromium-molybdenum alloy steel, medium alloy steel, high chromium cast iron, manganese steel, rubber, silica lining plates, ceramic lining plates, polyurethane, etc. The shapes include convex edges, corrugations, angular spirals, etc.
When grinding is the main purpose, the lining plate is required to have a strong ability to push the grinding body. At the same time, the lining plate should have good impact resistance. High manganese steel 3 has sufficient impact resistance toughness, but is not wear-resistant and Easy to deform, most of them have now switched to alloy steel or chromium-molybdenum alloy steel lining plates in the dual-media quenching process. Comparing several wear-resistant materials, alloy steel has the best performance and longest service life in the dual-media quenching process. Its superiority is more obvious in large and medium-sized ball mills, and it is the most cost-effective.
Domestic high manganese steel linings for ball mills are gradually being replaced by medium alloy steel linings. However, with the continuous application of medium alloy steel linings in ball mill linings, they have gradually replaced manganese steel and other linings in the market. Develop mainstream.
In addition to protecting the cylinder, the cylinder lining also affects the movement patterns of the grinding body. In order to adapt to the requirements of various working conditions (crushing or fine grinding), the shapes and materials of the lining are also different. When crushing is the main purpose, the lining plate is required to have a strong ability to push the grinding body, and at the same time, the lining plate should have good impact resistance. When fine grinding is the main purpose, the protrusion of the lining plate is relatively small, and the impact on the grinding body is The pressing effect is weak, the impact is small, and the grinding effect is strong. The liner is required to have good wear resistance.
