Bond work index value of these components mixtures is greater than the Bond work in-dex of harder components, clinker. Oner (2000) have conducted a research of clinker and blast furnace slag mixture Bond Work Index in different mass propor-tions. He found out that these values are always lower than the Bond Index obtained

In this regard calculation of work index of limestone made by standard Bond grindability test. Ball mill was employed to conduct the grinding test of seven different samples. Among all seven samples collected from the different faces of quarry, Bond work index of limestone Face4A results less than 20kwh/t, remaining 6 samples are marked as hard -

The Bond work indices of mixtures were not simply weighted averages of the component work indices, and they were higher than the work index of the harder component clinker.

The Bond work index is a measure of ore resistance to crushing and grinding and is determined using the Bond grindability test. Its value constitutes ore characteristic and is used for industrial

Nov 04, 2013 revolutions within a test mill that were required to produce a surface area of 350 m2/kg. The second was a breakability test which assessed the height that a steel ball must be dropped from to break a clinker nodule. I don't know if this testing is still available but it was useful when grinding a number of different imported clinkers. Reply

1989). The work index (Wi) is calculated in a laboratory-scale ball mill with Bond equation. The Bond work index has been widely used in designing full-scale mills but the Bond test is rather complex, lengthy susceptible to procedural errors and this is why attempts have been made to abbreviate and simplify Bond test procedure (Weiss, 1985). 2.

Bond Ball Mill Work Index Clinker. Bond Work Index - an overview ScienceDirect Topics. The ball mill work index laboratory test is conducted by grinding an ore sample prepared to 100% passing 3.36 mm (6 mesh) to product size in the range of 45-150 µm (325-100 mesh), thus determining the ball mill work index (WiB or BWi).

The work index . W. i. was defined by F. Bond as the specific energy (kWh/ton) required to reduce a particulate using a novel ring mill, a laboratory ball mill, a labora- study for quartz grinding, using the semi continuous process described above and for screens of 850, 425, 212, 106 and 53 .

Nov 01, 1998 Bond ball mill grindability tests. Results of the Bond tests are given in Table 1. Experimental work indices for singly ground clinker and trass are the mean of two replicates. The replicate values are 13.08 and 13.89 for clinker, and 11.52 and 11.78 for trass. The Bond work index of a clinker–trass admixture is not simply the weighted

2Sep 08, 2013 The difference between the Energy Index and the Bond Work Index is that the Bond index is intended for use with actual mills whereas the Energy Index is directly obtained from the results of laboratory mills. However, the Energy Index is directly related to the Bond Work Index by the formula;-Work Index = C * Energy Index (where C is a constant

Bond Work Index Formula. The ability to simulate the Bond work index test also allows examination of trun ed ball mill feed size distributions on the work index For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill see Figure 3 10 a question arises as to whether this practice will alter the ball mill work index BW i
