Ball Mills
Ball Mills. Ball mills have been the primary piece of machinery in traditional hard rock grinding circuits for 100+ years. They are proven workhorses, with discharge mesh sizes from ~40M to <200M. Use of a ball mill is the best choice when long term, stationary milling is justified by an operation.

This ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. Due to the difference of its slurry discharging method, it is divided to two types: grid type ball mill and overflow type ball mill.
Winning the Metal: Ore Mills of the West
At this time, the stamps are the heaviest in use in the country. The ore is taken from the mine and crushed to a suitable size in an Allis-Chalmers gyratory crusher, carried to the storage bin in an ore car. Eventually, a 4 ton ore car is hauled up a tramway and ore stored in a second bin at the mill. This bin feeds direct to the stamps."

LECTURE NOTES
fuel and energy consumption per ton of metal smelted. 6. Reduction of the total smelting cost: As there is a partial separation of gauge from the ore, lesser amount of upgraded ore is to be smelted for a particular output capacity. This reduces the fuel and energy consumption per ton of metal smelted. 7. Reduction of the total smelting cost:
BOND'S WORK INDEX: WHAT IT IS AND WHAT IT ISN'T
The reason for this variation in ball mill work index is because the ore at Mt. Milligan has an intrinsic exponent of –0.45 in the 100 µm to 200 µm size range, not the –0.50 exponent empirically measured by F. Bond. The work index increase between 100 µm and 76 µm is due to a porphyritic grain size that causes a spike in energy
