What are the types of grinding media steel balls

- Jul 04, 2018 -

Grinding medium steel ball is a pulverizing medium used in a ball mill. The steel ball used to pulverize the material in the mill is actually an abrasive body. Grinding medium steel balls can be divided into many types and are widely used in various industrial fields.


For example, a grinding medium steel ball made of chrome cast iron is called a chromium alloy cast iron grinding ball; a grinding medium steel ball made of nodular cast iron is called a spheroidal graphite iron grinding ball: a base structure bainite ball iron mill obtained by heat treatment. The ball; the matrix structure obtained by the heat treatment is mainly a martensite ductile iron ball.


At the same time, there is also a grinding medium steel ball which is hot-rolled from round steel produced by steel mills. The whole process is automatically controlled, the hardness of the steel ball is uniform, the hardness of the core is high, the breaking rate is low, and the impact value of the steel ball is large. And grinding medium steel balls that are forged by train hoeing, which are low in cost.


In addition, there are grinding medium balls such as cast steel balls, forged steel balls, rolled steel balls and bearing steel balls. The balls are widely used in metallurgical mines, cement building materials, thermal power generation, flue gas desulfurization, aerated concrete, magnetic materials, Chemical, coal water slurry, pellets, slag, ultrafine powder, fly ash, calcium carbonate, quartz sand and other industries
