"MGS01" new material, which add some chromium and rare-earth element in the high manganese steel. After using this new material, our customer reduces the consumption of the ball mill liner. Every set of ball mill liner can crush more than 750,000 tons of raw material. Compare with other material, the wear resistance of the board is increased by 34%.
Ball grinding mill is Formed a closed system with air classifier. Coarse material will be back to ball mill to grind again, and qualified material will go to be packed by worker or packing machine. Advantage (1)Special design, saving energy about 30% (2)Easy maintenance and operation (3)Low operating cost

The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones. The cyclones send correct-size material on to flotation and direct oversize material back to the ball mill for further grinding.

Ball mill - Wikipedia. A ball mill is a type of grinder used to grind and blend 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.

Nov 18, 2008· Summary The Ball Mill is designed to grind materials by turning the cylindrical shell with grinding medium (e.g. steel balls) put in the shell, and has a simple structure and ease of handling. Furthermore, The Ball Mill of a large capacity has been available to a very extensive range of applications in both dry and wet 14. References 1.
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium.
Ball mill - Wikipedia. The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and non-ferrous metals.
In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill & ball mills, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.

cement industry the ball mill was really an epoch-making breakthrough as for almost 80 years it was the predominant mill for grinding of raw materials and coal, and still today is the most used mill for cement grinding. Over the last three decades the vertical roller mill has become the preferred mill for grinding of raw materials.
The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.
