Vertical Mill Grinding Balls

HT-HI castings are produced with an abrasion resistant iron with a minimum of 550 brinell hardness. The lifespan of our wear-resistant parts is more than twice as long as that of the ordinary ones. We strictly control the hardness, impact strength, elements, metal components and other parameters of our products, in order to ensure our customers only reduce high-quality vertical mill grinding balls.

To date, we have become the Chinese largest manufacturer of the wear-resistant parts for concrete and asphalt mixing plants. Each year we can produce 20,000 tons of wear-resistant Cr/Mn hard cast iron castings. Our highly-skilled engineer team can offer you complete technical support.

    We offer the following castings
  • Hollow ball for Vertical mill

Material Standards
Casting steel: DIN, JIS, EN, ASTM, GB
White chromium alloy castings: Cr content of 8%-29%.
Ni hard cast iron: containing 2%-6%
