  • Grinding control strategy on the conventional milling

    milling circuit consists of a rod mill followed by a ball mill in series. Crusher product (-9 mm) is fed to the rod mill and the water is fed in ratio to the ore feed mass. The rod mill discharge is pumped without any further water addition to the first ball mill. The ball mill discharges to a sump where water is

  • A specific energy-based size reduction model for batch

    A particle size reduction model has been developed as the first component of an upgraded ball mill model. The model is based on a specific energy-size reduction function which calculates the particle breakage index t 10 according to the size-specific energy and then calculates the full product size distribution using the t 10 –t n relationships and the mass-size balance approach.
