The Laboratory Comparative Work Index gives an approximate Bond Work Index for an ore sample. This can then be used with Bond's Third Theory of Comminution to calculate net power requirements needed for grinding. The test depends on laboratory batch grinding and uses a comparison with the grinding of an ore of a known Bond Work Index.
The Bond Ball Mill Work Index is a measure of the resistance of the material to grinding in a ball mill. It can be used to determine the grinding power required for a given throughput of material under ball mill grinding conditions. It is a 'locked cycle' test conducted in closed circuit with a laboratory screen.
Wi = Bond work index (either Imperial or Metric units) P = The 80% passing size of the ground product in µm F = The 80% passing size of the feed in µm . The test is a closed circuit dry grindability test performed in a standard ball mill. It can be performed at mesh sizes ranging from 28 mesh to 400 mesh.
Bond Yield Versus Price As bond prices increase, bond yields fall. For example, assume an investor purchases a bond with a 10% annual coupon rate and a par value of 1,000.
An index-linked bond is a bond which has its coupon payments adjusted for inflation by linking the payments to some inflation indicator, such as the Consumer Price Index (CPI) or the Retail Price .
Here there are given tables from various sources for the Bond work index values of mining materials (ores, industrial minerals and rocks). These work indexes can be used for the determination of tumbling mills (rod, ball mills) power.
Determination of the Bond Work Index of Ores A.J.C.Taguiam Department of Mining, Metallurgical and Materials Engineering University of the Philippines, Diliman [email protected] Abstract The Bond work index refers to the measure of a material's hardness or resistance to crushing and grinding, and is numerically expressed as kilowatt hours per short ton.
