Graduated cylinder Analyssete Sieve Shaker and screens Procedure 1) Do a screen analysis on about 250 grams of the assigned -6 mesh ore sample. Determine the feed 80% passing size (F 80) and the weight percent -65 mesh.
2016-12-27 micrometers in size. According to the Bond standard procedure, the work index is determined by simulating a dry grinding in a closed circuit in the Bond ball mill to achieve 250% circulating load (Bond, 1949, 1952, 1961). The test is performed on a raw material approximately weighing 10 kg, which coarseness is 100% -3.327 mm.
