Bond Ball Mill Grindability Test. The Bond Ball Mill Work Index (BBWi) test is carried out in a standardised ball mill with a predefined media and ore charge. The Work Index calculated from the testing can be used in the design and analysis of ball mill circuits. The test requires a minimum of 10kg of sample that has been stagecrushed to
Ball Mill Grindability of a material depends upon its hardness, structure, the manner in which it is fractured. Get Price ; Comminution Services SGS The Bond Ball Mill Grindability Test determines the Bond Ball Mill Work Index used to determine net power requirements when sizing ball mills. The test is a closedcircuit, dry grindability test.
standard ball mill grindability test procedure in namibia. All standard ballmill tests are conductetl at 250 per cent circulating load and the number of revolutions in the mill necessary to obtain this circulating load at any grind ing period is estimated from the results of the previous period
The Bond ball mill work index is one of the most commonly used grindability tests in mining, and is often referred to as the Bond work index.. The test is a ''lockedcycle'' test where ground product is removed from test cycles and replaced by fresh feed.
#0183;#32;Our findings would also suggest that the BWI is a valid test for predicting the potential for mill choking of biomass in a tube and ball mill. HGI, however, appears to be a poor method of predicting the grindability of biomass in vertical spindle mills. A new standard grindability test is required to test the grindability of biomasses in such
