Aug 01, 2005 The Bond work index is one of the most useful and interesting parameters used in designing grinding equipment. However, it must be obtained under restrained conditions, especially in regards to the Bond standard lab mill. The main objective of this study is to show how this index can be obtained using a Denver ball mill, which is present in most mineral processing laboratories. The …
(2006). This test now includes a Bond Ball mill work index test. The Macpherson test is still being offered by some testing facilities. This dry test requires at least 180 kg of material. Morrell (2004) formulated an AG/SAG speci? c energy generator based on a drop weight index Value (DWi).

Test data from the Bond ball mill work index test is used to calculate the fine grinding index (M ib). The M ia and M ib indices are used to calculate specific energy for the coarse (W a) and fine (W b) components of the total grinding specific energy at the pinion (W T) according to Equation 7. W i = 4.K.M i.[Pf(P)-Ff(F)] (6) W
Testwork: Bond Ball Mill Work Index. 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 'locked-cycle' test where ground product is removed from test cycles and replaced by fresh feed. The test much achieve a steady-state before completion.
carried out with the Bond ball mill and rod mill grindability tests. As discussed earlier in this paper, it is important in this case to match the reduction size of the test to that desired from the industrial mill. As such, primary ball mills should be designed with the rod …
This Ball Mill can be used continuously or it can be used for any number of revolutions, according to the type of grind desired. For instance, the Fred C. Bond Grindability Tests were made in the Bico Mill running at 70 revolutions per minute, with a charge of 285 iron balls ranging in size from 3/4 inch to 1-1/2 inch in diameter, and weighing ...
Determination of the energy consumption for ore grinding in a Bond ball mill requires samples of standard size, because changes in the size of the samples cause the change of the Bond work index (Magdalinovic et al., 2012). Due to the Bond test complexity and length, as well as the possibility to make mistakes during

Correction of Bond Ball Mill Work Index Test for Closing. The goal of this work is to create an equation to adjust a Bond ball mill work index from one P 80 basis to another. The proposed model consists of two components the variable coefficient that is determined from a specific work index determination and .
