  • Magnetic Separation Technology Can Improve Grinding

    The trunnion magnet is an enhanced system for separation and removal of balls chips or scats in a typical ball or SAG mill operation. The trunnion magnet is mounted at the SAG ball mill discharge point and is used in place of a trommel screen.

  • Optimizing your SAG mill operationInternational Mining

    In multi-stage ABC/SABC circuits the AG or SAG mills are in closed circuit with screens and pebble crushers. The mill discharge from these mills consists of slurry which goes to the ball mills for further grinding and coarse pebbles/rocks which are crushed and sent back to the mill.

  • Dry Grinding Attritors Batch or Continuous Mills

    The SD Dry Grinding Attritors can be operated in both continuous and batch processing applications. In the continuous operation the material is fed into the vessel at the top. It then migrates through the agitating media bed where it is processed to a desired particle size and is discharged through metering bar grids at the bottom of the tank.
