Grinding ball can be divided into three types by production technology. They are called hot rolling ball, forged grinding ball and cast grinding balls. About cast grinding balls, it can be called high chrome cast grinding ball, middle chrome cast grinding balld and low chrome cast grinding ball according to the chrome content. For low chrome cast grinding balls and middle chrome cast grinding balls, they have poor wear resistance and easy to break compared with high chrome cast grinding balls, so these grinding balls are not recommended. About high chrome cast grinding balls, it is a high qualitied grinding balls and it is warmly welcomed by clients. General speaking, the higher hardness of the grinding balls is, the better wear resistance of the grinding balls is. But if the hardness is too high, it may cause grinding ball reduction of impact toughness. What is more, the hardness of grinding balls must considerate the hardness of the lining plate and the material of lining plate. So how to handle well the hardness of grinding balls and toughness is the key to improve the wear resistance of grinding balls. So how to produce grinding balls are very important. For example, high chrome cast grinding balls, in production and design grinding ball production equipment, the solidification sequence and feeding sequence should be adjusted reasonably, so the grinding balls can get dense internal tissue. Grinding Ball heat treatment machine decides the mechanical properties and carbide distribution of grinding balls. There are chrome and other castings in cast grinding balls. How to make these alloy form the hard carbide, it is a key factor when design heat treatment process. The grinding balls quality is mianly decided by the grinding balls equipment and its production technology. Dexin does not professionally producesgrinding ball equipment, but also technical supporting in production. For more detail information. Freely contact with us.

Through the domestic and international market demand analysis, the mining industry has a great demand for grinding balls ! It has broad market space.
View More →● Hardness of grinding steel ball. General speaking, The better wear resistance, the higher hardness. ● Production technology of grinding steel ball. The more dense of grinding steel ball and the finer of the crystals, the better wear resistance. ● Carbide. The more carbide, the better wear resistance. ● Heat treatment technology. The wear resistance of grinding steel ball can be best developed only when the hardness value and impact value match well.

For middle chrome balls and low chrome balls, it just needs tempering. There are many types about mill ball heat treatment equipment. It can used by electricity or by natural gas. Both are very welcome. The capacity can be from 5ton to 60 ton.

Alloy sand box is suitable for balls from diameter 10mm to 40mm, metal mold is for balls from diameter 40mm to 150mm. For alloy sand box, the advantage is high production. For metal mold, the advantage of balls is high quality. So how can we choose for balls 40mm production. If wanna high harness and better quality, 40mm steel ball metal molds are recommended.
