Grinding Media - Union Process

Forged Steel Balls are used for gold mining, cement factories, oil processing and large scale industrial applications. They are made by machine (standard) sizes 20mm–75mm. They are manually made (hit by air hammer) sizes 75mm–125mm. They have hardness 55–63 HRC. All forged balls are through-hardened, and shipped in 55-gallon steel drums.

Cement Ball Mill

Cement ball mill is not only suitable for over-flow grinding, but also applicable for cyclic close-flow grinding together with powder collector. There are two ways of grinding: the dry way and the wet way. Features 1. Can work with grinding and drying equipment simultaneously. 2. Easy to adjust the fineness of grinding products.
