Chrome Cast Iron Grinding Ball
Introduction: Chrome alloy casting ball has the advantages of high hardness, low wear, good toughness, less breakage and certain impact hardening ability.
Classification: It can be classified into high-chrome alloy casting ball, medium-chrome alloy casting ball and low-chrome alloy casting ball depending on different chromium content.

Product introduction
Application
It is widely used in the field of cement and building materials, thermal power, the mining mineral processing, steel and chemical industry, aerated bricks and alumina industry.
Product Advantage
1. Specifications: Φ10mm-Φ130mm
2. Product material, hardness distribution (HRC), impact value (J/cm2), metallographic structure, breakage rate, falling ball fatigue times and other technical standards and usage indicators (service cycle, service life, tons of material product consumption, usage specifications, etc.) can be customized according to the customers’ actual working conditions or contract agreement.
3. The grinding ball can maintain stable gradation of grinding body and high grinding efficiency for a long time, which is conducive to the stability and improvement of output and quality per unit time of ball mill, and greatly reduce the use cost and clearance times of grinding body.
