the Bond work index is relatively consistent anywhere in the world, and should be very repeatable [5]. BOND ROD MILL GRINDABILITY The Bond rod mill grindability test is performed similarly to the ball mill test. The feed sample is stagecrushed to #189; () and the test is run under a circulating load. The test can
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

Bond Work Index Test Ball Mill. US 13,800. The FC Bond Work Index Test Ball Mill was designed by F. C. Bond for use in determining the Bond Index, a measure of grindability and power required for grinding applications. The FC Bond Mills are used in laboratories throughout the world. A copy of Fred C. Bonds Method of Crushing and Grinding for
This Grindability Test or Bond Ball Mill Work Index Procedure is used to determine the Bond Work Index of minus six mesh or finer feed ore samples. These equation application methods are used to process lt;1/2 ore samples in a Ball Mill using a standard ball charge. Below describes in general terms the Bond Work Index Procedure used by a Professional Metallurgical Testing Laboratory. If you
The grinding jar for the Bond Index Rod Mill is 12 x 24 in size and has a waveshaped design. 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 mm whereas Ball Mill Work
The test work program was carried out on those five ore samples obtained from the copperporphyry orebodies. Total of 38 Bond work index tests, including duplicates, were done. Standard Bond ball mill test procedure were carried out on crushed ( mm / 6 mesh) material at different
Abstract: 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 comminution plants designing. Determining the Bond work index
Bond Ball Mill Grindability Test. The test determines the Bond Ball Mill Work Index which is used with Bonds Third Theory of Comminution to calculate net power requirements*. Various correction factors may have to be applied. W = Wi (10/P 10/F) Where W = Net power consumption in kWh/t Wi = Bond work index (either Imperial or Metric units)
3 STANDARD BOND TESTS The Bond''s standard ball mill is used to determine the work index value of differ ent samples. The Bond work index is defined as the kilowatthours per short ton required to break from infinite size to a product size of 80% passing 100 #181;m. If the breakage
The ball mill work index laboratory test is conducted by grinding an ore sample prepared to passing mm (6 mesh) to product size in the range of 45150 #181;m (325100 mesh), thus determining the ball mill work index (Wi B or BWi). The work index calculations across a narrow size range are conducted using the appropriate laboratory work index determination for the material size of interest, or by

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
Here is the old AllisChalmers 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 1000cc 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
