Seven Tips Increasing Ball Mill Grinding Efficiency

The classification efficiency has an implied influence on grinding efficiency. The high classification efficiency means that the qualified particles can be high-efficiency discharged in time. The low classification means most of the qualified particles are not discharged and returned to ball mill regrinding, which easily causes over grinding.
