White Iron Ball Mill Liner in general refers to the alloy white iron with the chromium content at 12%~26%, the carbon content at 2.0%~3.6%. White Iron Ball Mill Liner distinctive features is that the M7C3 type eutectic carbide micro hardness is HV1300~1800. White Iron Ball Mill Liner’s eutectic carbide is distributed on the base, martensite(the most hard metal matrix organization), in discontinuous network and isolation, which reduces the fragmentation of the matrix effect. As a result, the high chromium Ball Mill Liner has high strength, strong toughness and good wear resistance features , which is widely used at Mining ,Cement and power industry .
White Iron Ball Mill Liner is recommended to be using at low impact working condition such as :
1. Belt conveyor liner for Mining industry.
2. Cement plant Ball Mill .
3. Chemical industry Ball Mill .

Application of White Iron Ball Mill Liner
Our White Iron Ball Mill Liner are widely used in the grinding stage for mining industry, cement industry, thermal power plant, paper-making and chemical industry etc.
A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. It is partially filled with balls. The grinding media are the balls, which may be made of steel (chrome steel), stainless steel, ceramic or rubber. The inner surface of the cylindrical shell is usually lined with an abrasion-resistant material such as manganese steel or rubber lining. Less wear takes place in rubber lined mills. The length of the mill is approximately equal to its diameter.
