In the industrial field, wear balls are an indispensable and important component. Although it may seem insignificant, it plays a key role in the production process in many industries.
Wear-resistant balls, also known as wear-resistant media for grinders, are mainly used to crush materials in ball mills to make the materials grind finer to meet the use standards.
There are many types of wear balls. The common ones are as follows:
1. Chromium alloy cast iron grinding balls made of white cast iron with chromium as the main alloying element. This kind of grinding ball has certain wear resistance and corrosion resistance (industry standard reference: "YBT092-2019-alloy cast iron grinding ball").
2.The casting grinding ball made of ductile iron can obtain the matrix structure mainly bainite or martensite after heat treatment, which is referred to as bainite ductile iron grinding ball and martensitic ductile iron grinding ball respectively.
3. Forged steel balls made by hot rolling of round steel from steel mills. The whole production process is automatically controlled, the steel ball hardness is uniform, the core hardness is high, the crushing rate is low, and the impact value of the steel ball is large (industry standard reference: "YBT091-2019-Forged Steel Ball").
4. The steel ball made of the cutting and forging of the train reel is relatively low in cost, but the hardness of the steel ball core is low, it is easy to break, and the wear resistance is also poor.
Different types of wear-resistant balls have their own characteristics in terms of performance, and are suitable for different working conditions and industries. For example, wear-resistant balls can be seen in ball mills in mining, cement building materials, thermal power generation, chemical industry and other fields.
