Casting Grinding Balls

Short Description:

This Casting Chrome Grinding Ball is a high-quality grinding ball designed to provide superior performance and long-lasting durability. Manufactured using a high chromium alloy and carefully heat-treated to ensure optimum hardness and strength, these balls are designed to provide superior resistance to wear and corrosion. The grinding ball is designed to provide superior grinding performance in a wide range of applications, including ball mills, rod mills, and cement mills. Additionally, they are also suitable for use in various other industries such as mining, chemical processing, and industrial applications.

Product Detail

Product Description:

ZenTi casting steel balls are shaped by metal mould rather than sand mould, which makes our products have stable structure, better grinding performance and uniform sizes. Our advanced producing technology and newly invested producing lines enable our products to have higher abrasion resistance and longer life. With more than 15 years of production experiences and professional services, our products have gained remarkable good feedbacks and recognization from our clients in more than 30 counties.
