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

Very often the pulverisers experience unequal flow velocities and repeated grinding. The unequal flow distribution in the air housing has an effect up to the classifier. Furthermore, it has become apparent that the different components fitted in the grinding chamber cause secondary and tertiary swirl motions in different forms and intensities.
