bond work index ball mill design and safety factors the Bond work indexes of crushing, rod milling and ball milling. The authors exemplify the described method application and compare the obtained estimates with the factual field test data.

The Bond Ball Mill Work index (BBWi) is the industry standard procedure for assessing the grindability of ores. The test involves conducting a locked-cycle grinding test using ond's standard mill design. The locked-cycle test enables a batch process to emulate the grinding behaviour of a continuous mill with a 250% recirculating load.

The presentation of this work has been done on 19th June 2017 at Luleå University of Technology. This work is a part of PREP project (Primary resource efficiency by enhanced prediction).

The bond grindability index and work index of ball mill were determined for different feed characteristics by varying the number of balls involved in grinding operation in the ball mill. The higher specific rate of breakage was obtained for new or smooth surfaced balls than old or rough surfaced balls.
