dry grinding in mineral recovery

  • Why HPGRs are revolutionising mill circuits

       High Pressure Grinding Rolls are generally thought to only be effective in controlled "dry" grinding applications however (depending on the material saturation level) they can readily process minerals well above 10 moisture. This gives HPGR s the flexibility to fit into a wide array of applications with both wet and dry classification.

  • A comparative study on the effects of dry and wet grinding

       Dry grinding has significantly lower media and liner wear than wet grinding thus the Fe concentration in the pulp of downstream process for the same mineral is relatively lower after dry grinding. Dry grinding produces rougher surfaces (mechanically activated centers) and more agglomerated particles than wet grinding.
