Energy Efficient Ball Mill Circuit – Equipment Sizing

BALL MILL CIRCUIT SIZING METHODS The basis for ball mill circuit sizing is still Bond's methodology (Bond, 1962). The Bond ball and rod mill tests are used to determine specific energy consumption (kWh/t) to grind from a given feed 80% passing size (F80) to 80% passing size product (P80). Variations in the original Bond methodology
