(PDF) Energy Efficient Ball Mill Circuit – Equipment

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).

Dynamic Modelling of Temperature in a Wet Ball Mill Based

Sep 01, 2019· Energy balance data is related to mill temperature where the latter is believed to be a primary indicator of in-mill process dynamics [21, 12]. It is a known fact that the biggest part of energy introduced in a ball mill is converted into heat, with only about 3 - 5% of this energy being used to grind the ore to the required fineness.
