This reduces ore to manageable sized particles and releases its valuable components while discarding non-valuable ore, called gangue. For effective comminution, large-sized ore is crushed in a crusher developed for this specific process, and the resultant smaller ore is achieved using rotating steel mills. With manageable sized ore in-hand, the ...Web

In addition, the value of the BWi determines the energy required for crushing and milling (depends on the BWi type, e.g., crushing work index, Bond ball mill work index, and Bond rod mill work index), and this measure can be used to optimize processing throughput. 2.2 Bond Ball/Rod Mill Work IndexWeb

In those days, 3 stages of crushing, and rod and ball mill grinding, were common in comminution flowsheets. Bond's Rod Mill Work Index (RM Wi) and Ball Mill Work Index (BM Wi) tests provided good designs for grinding mills. If the design was 1200 t/d, each stage had to be able to produce 1200 t/d or (54 t/h at 92.6% availability).Web
