Industrial Solutions Autogenous, chamber for iron ore grinding. The single-compartment mill is ideal for the grinding of fine-grained feed material. One typical application is the combined grinding and drying of iron ore concentrate with a high feed moisture content (up to approx. 8 %). High-efficiency separators minimise the power consumption of dry grinding systems.

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.
