HMR NMCADI⁺¹⁰Case analysis of grinding ball

There are two series of grinding operations in a copper ore dressing plant in Mongolia, two semi autogenous mills with the same specifications, and the operation conditions are completely the same. Series 1 adopts Φ 125mm nmcadi + 10 grinding balls produced by HMR group, and series 2 adopts Φ 125mm forged grinding balls produced by other manufacturers.

Φ9000mm×3000mmSemi autogenous mill

After 1.6 months of operation, the statistical analysis results of grinding ball use effect are as follows:

The average ball consumption of HMR nmcadi + 10 grinding ball is 327 g / T, and that of other manufacturers is 786 g / T. the unit ball consumption is reduced by 58.4%.

HMR nmcadi + 10 grinding ball shows the perfect combination of hardness and toughness, work hardening in the process of use, low wear rate, low crushing rate and no loss of roundness.
