Evaluation Of Dry Grinding Using Hpgr In Closed Circuit

Evaluation Of Dry Grinding Using Hpgr In Closed Circuit

Feb 01, the specific grinding energy of a 2.44 m interior diameter wet overflow ball mill is usually calculated using the bond work index and bond’s third law equation : (3) w = 10 w i (p 80-0.5-f 80-0.5) where f 80 is the 80% passing size of the feed (μm), p 80 is the 80% passing size of the product (μm), w is the specific grinding energy (kw h/t), and w i is the bond work index (kw.For ore a a bond ball mill work index value of 17 kwh/t was reported. for ore b a bond ball mill work index value of 15 kwh/t was used. further comminution tests will be required in the future to confirm this is representative of the ores to be processed. the bond index values generally indicate that grinding is moderate power.
