Magotteaux automatic ball charger (ABC) - ScienceDirect

Magotteaux has developed an improved system to automatically add grinding balls to grinding mills, the Magotteaux Automatic Ball Charger (ABC). The ABC adds relatively small weighed increments of balls, typically 100 kg, as required, rather than the large increments, 1,000-10,000 kg, that are common in manual charging systems.

The experimental results showed that the Abbott-Firestone curve can evaluate the lifter surface topography. The wear rate of the lifter specimen is increased first and then decreased with mill speed and grinding media size. Increasing ball filling will increase the wear rate, and the grinding media shape of ball has a maximum wear rate.
