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.
