Bond Ball Mill Grindability Test. The test determines the Bond Ball Mill Work Index which is used with Bond’s 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) P = The 80% passing size of the ground ...
The F.C. Bond Ball Mill is a small universal laboratory mill used in calculating the grindability of all ores. GRINDABILITY IS THE NUMBER OF NET GRAMS OF SCREEN UNDERSIZE PRODUCED PER REVOLUTION. This Ball Mill can be used continuously or it can be used for any number of revolutions, according to the type of grind desired. For instance, the Fred C. Bond Grindability Tests were made
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 (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 ...

The Bond ball mill grindability test is performed according to the original Bond procedure [4]. It requires 10kg of minus 6-mesh (3.35mm) material that is preferably prepared at the testing facility, by stagecrushing the sample to 100% passing 6-mesh, but normally less than 5kg are actually used in the test. The test is closed with a fine screen (typically in the range 65 mesh to 270 mesh ...

Bond test does not exceed 2.6%. The aim of this study was to develop a new method for assessing the Bond work index in a ball mill (BBWI), which is based on a first order kinetics present in the Bond ball mill for grinding mineral raw materials (Austin et al., 1981; Ahmadi and Shahsavari, 2009). Theoretical basis of quick procedure
