— To determine the ball mill work index of the samples (Table 1), around 10 to 17 kg of ore was required for the particle size crushed to −3.35 mm (Amtech, 2006). The 700 cm 3 ore sample weight is fed to the Bond mill at a −3.35 mm size range. The test was started with an arbitrarily chosen number for mill revolutions (N = 50, 100, 150…).

bond ball mill work inde determination. determination of bond ball mill work index of limestone. A Bond Ball Mill Work Index test is a standard test for determining the ball mill work index of a sample of ore. It was developed by Fred Bond in 1952 and modified in 1961 (JKMRC CO., 2006). This index is widely used in the mineral industry for …
— The Bond ball mill grindability test is run in a laboratory until a circulating load of 250% is developed. It provides the Bond Ball Mill Work Index which expresses the resistance of material to ball milling.This happens after 7–10 grinding cycles, which shows that the procedure is a lengthy and complex one and is therefore susceptible to …
