MoreThe ability to simulate the Bond work index test also allows examination of truncated 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) of the material

MoreHere is the old Allis-Chalmers Bond Work Index Grindability Test Procedure. The standard feed is prepared by stage crushing to all passing a 6 mesh sieve, but finer feed can be used when necessary. It is screen analyzed and packed by shaking in a 1000-cc graduated cylinder, and the weight of 700 cc is placed in the mill and ground dry at 250 per cent circulating load. The mill is 12 in. x 12

MoreIn 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 -

MoreNov 04, 2013· The Bond Work Index is one practical method. the first was the SGI test which assessed the number of revolutions within a test mill that were required to produce a surface area of 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

At least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill. The Rod Mill Work Index (RWI) is used for particle size determination in a size range from 25 mm down to 2.1 mm whereas Ball Mill Work

MoreThe most commonly employed formula was developed by Bond and is as follows: Ømax = 20.17 X X [1] where, Example Ømax = biggest ball diameter, mm d20 = sieve dimension where 20% is retained, µm = 15,000 r = specific mass of material, grams / cm3 = 3.09 Wi = Bond Work Index, kWh / short ton = 13.49 Du = useful inside mill diameter, m = 3.5 Y

MoreA Bond Ball Mill, 12” x 12” of fabricated construction comes with electric motor and gear reducer drive, digital counter, jogging button to provide positioning of drum for loading and unloading, emergency stop button, 44 ½ lb ball charge, stand and receiving pan. Perform Fred C. Bond's grindability tests with this standard BWi test ball mill.

MoreThe 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.

Cement clinker grinding circuit to reduce the amount of feed from 80 through the particle size is the bond ball mill work indicators read more about the ball mill Wikipedia binder ball mill operating indicators clinker mechanical machinery 99 user comments on how to use a ball mill for clinker grinding model using

MoreSep 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

MoreNov 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

MoreLaporan Akhir Projek Penyelidikan Jangka Pendek Study of the The clinker samples collected also undergone standard Bond grindability test. The objective of the Bond ball mill test is to determine the so-called standard work index, .. carbonate found in

MoreBond 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

MoreInsmart Bond’s Ball-Mill Work Index is a measure of the resistance of the material to grinding in a ball mill. This Index is widely used in the industry for comparing the resistance of different materials to ball milling, for estimating the energy required for grinding and for ball mill scale-up.
