Casting Grinding Balls
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.
Application in grinding machines and areas:
·Ball mills / Vertical mills
·Mineral processing plants
·Mining industry
·Power stations
·Cement industry
·Steel Industry
