What is a wear-resistant steel ball

Update:02-09-2022
Summary:

Wear-resistant Carbon Steel Ball (grinding ball), also […]

Wear-resistant Carbon Steel Ball (grinding ball), also known as wear-resistant medium for grinding machine, is a consumable, the main purpose is to grind the material, so that the material can be ground finer to meet the use standard.

There are four kinds of wear-resistant steel balls: one is that white cast iron with chromium as the main alloying element is referred to as chromium alloy cast iron, and the cast grinding ball made of chromium alloy cast iron is called chromium alloy cast iron grinding ball; the second is, Casting grinding balls made of ductile iron are called ductile iron grinding balls, of which the matrix structure obtained by heat treatment is mainly bainite ductile iron grinding balls, referred to as bainitic ductile iron grinding balls; the matrix structure obtained by heat treatment is mainly Martensitic ductile iron grinding balls are referred to as martensitic ductile iron grinding balls.

 

The third type is a steel ball made of round steel produced by a steel mill, and the whole process is automatically controlled. The hardness of the steel ball is uniform, the hardness of the core is high, the breakage rate is low, and the impact value of the steel ball is large. The fourth type is to use a train This kind of steel ball is low in cost, but the steel ball core has low hardness, is easily broken, and has poor wear resistance.

 

Wear-resistant steel balls are widely used in metallurgical mining, cement building materials, thermal power generation, flue gas desulfurization, magnetic materials, chemical industry, coal-water slurry, pellets, slag, ultrafine powder, fly ash, calcium carbonate, quartz sand and other industries ball mill. The annual consumption of steel balls in the world is 30-50 million tons.
