2018-1-15 · 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 Bond 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.
