• Uses the changes in the mill load and power to automatically detect whether the mill is overloaded or underloaded. • Uses . safety controllers. to change the solids feed rate and feed water to prevent mill overloads. • Estimates the power load curve and optimum load. By optimising the mill power usage and preventing mill overloads,
The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and the system for discharging the output product. The size of a mill is usually characterized by the ratio “length to diameter” and this ratio most frequently varies from 0.5 to 3.5. The
