· pdf especially in grate discharge mills where the pulp level approaches zero at discharge. secondary ball mill balls experience significant levels of abrasive and corrosive wear, with insignificant levels of impact wear due to the small 2.5 – 60 mm diameters
· pdf turn-over, both actions improve milling performance through increased “ball-charge participation.” over throwing should be avoided, especially high-energy ball-on-shell impacts just above the charge toe, owing to the risk of ball-on-liner damage and excessive metal
designed for discharge efficiency the role of the grate is to allow the discharge of the material ground in the mill via the slots. with our range of alloys and design experience we can offer the longest possible lifetime with the optimal grinding efficiency.

discharge grates play an important role in determining the performance of autogenous, semi-autogenous and grate discharge ball mills. the flow capacity (grinding capacity) of these mills is strongly influenced by the discharge grate design––open area and position of apertures, as well as the performance of the pulp lifters.
