Laboratory Comparative Work Index
SGS can help reduce your risk by providing a thorough comminution test suite that includes the Laboratory Comparative Work Index.
This test is part of a suite that will help determine the operating parameters for ball mills and thus the economic viability of your project.
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.
This test is used where insufficient material is available or the sample is not coarse enough for a Bond grindability test. The feed sample requirements depend on the size of mill and the amount of material available.
