Working ·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 stage-crushed to 100 passing size of <3.35 mm.
Ball Mill (grinding mill) The Ball mill is a key equipment for regrinding.Ball mill is widely used in the field of cement the silicate product new type building materials fire-proof materials chemical fertilizer black and non-ferrous metal glass ceramics and etc.
The mill product can either be finished size ready for processing or an intermediate size ready for final grinding in a rod mill ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening a rod mill and some or all of the work of a ball mill.
The Rod Mill Work Index (RWI) is used for particle size determination in a size range from 25 mm down to 2.1 mm whereas Ball Mill Work Index (BWI) is used for the range from 2.1 mm down to 100 µm. Adjustment of grinding parameters
