The complete set of ball mill rubber lining plates consists of end lining plates (grid type is grate plate), end lifting bars, center ring (grid type is center guard plate), fillers, cylinder lifting bars (also called layering bars), cylinder lining plates, manhole doors, fasteners and other parts. Rubber linings are suitable for wet grinding processes and are now being used in dry grinding that requires strict metal impurities (iron).

Anti-corrosion rubber lining varieties include: Hard, semi-hard, soft, single layer, double layer, black, colored, non-toxic, white and other products.

Anti-corrosion lining, also known as rubber lining, is divided into four categories: 1. Equipment anti-corrosion lining 2. Mill lining 3. Flotation machine lining 4. Flue gas desulfurization lining Anti-corrosion lining is an unvulcanized, pre-vulcanized or vulcanized rubber plate or sheet to prevent equipment corrosion. The technology of using lining rubber sheets to form a continuous isolation covering layer on the working surface of metal or other materials is called rubber lining technology. Lining rubber can be divided into soft rubber, hard rubber and semi-hard rubber. It is generally made of NR, CR and SBR according to the usage conditions. The manufacturing of linings includes surface treatment of metal substrates, lining rubber sheet processing, cutting, laminating and vulcanization. As a chemical anti-corrosion and anti-mechanical wear material, lining rubber sheets are widely used as linings for chemical equipment and linings for mining and metallurgical mud pumps, flotation machines, mills, cement mills for the building materials industry and other equipment. Purpose of rubber lining Rubber lining has the ability to protect metal or other substrates from erosion by various media. Various rubber linings can not only withstand the corrosion of acids, alkali, inorganic salts and various organic substances, but also have good comprehensive properties, such as elasticity, wear resistance, impact resistance and adhesion properties of metals and other substrates. Rubber lining can be widely used in petroleum, chemical industry, fertilizer, metallurgy, electric power, food, medicine and environmental protection industries. Such as various acid and alkali storage tanks, reactors, and floor isolation layers in the chemical, fertilizer, and petrochemical industries ； Ships, trains, and automobile tanks transporting acids and alkalis ； Electrolyzers for hydrometallurgical industry and chlor-alkali industry ； Power station water treatment equipment, boiler industry softened water equipment ； Pickling system in steel rolling mill ； Storage tanks for beer, soybeer, wine and vinegar ； pharmaceutical equipment ； Thermal power plant exhaust desulfurization device ； Anti-corrosion seepage layer in sewage treatment plants, etc. Characteristics of rubber lining 1. Excellent corrosion resistance: Except for strong oxidizing acids such as concentrated sulfuric acid and chromic acid and aromatic alkanes, it has good corrosion resistance to almost all media. 2. Good corrosion resistance: The soft rubber lining with good elasticity can not only absorb mechanical vibration, but also absorb the corrosion caused by the stirring of materials with strong friction properties. Rubber linings are particularly suitable for applications in chemical plants where corrosion resistance and wear resistance are required. 3. Strong adaptability: The specially formulated rubber sheet lining can be freely deformed into any shape before it is vulcanized, so lining construction can be carried out on complex equipment. The bonding strength between rubber and metal body is high. The rubbers are combined with each other and can become one after vulcanization. They are more reliable than welding and can be used for lining on high-speed rotating machines. Applicable range (Φ25-Φ4000mm) storage acid, alkali tanks, oil storage tanks, reactors, pumps, valves, carbon removers, various pipelines, and sealed containers used under high pressure. Types of Rubber Linings Our company offers nearly 70 different types of protective linings. Its rubber types include all general rubbers, special purpose rubbers and polyvinyl chloride.
