circuit design the work index parameter is widely used in tracking mill performance. Due to the age and lack of controls for the test many laboratories have some variation in BBMWi test equipment and even processes such as media charge or mill liner variations. The JK Bond Ball Mill (JKBBM) test procedure is

The median Bond ball mill work index and Bond rod mill work index will be similar for most projects thought significant variation can manifest for any one particular sample. Relation of Bond ball mill work index and crushing work index. Rarely is there a relationship between the Bond ball mill work index and the Bond crushing (impact) work index.

The Bond ball mill work index is one of the most commonly used grindability tests in mining and is often referred to as the Bond work index.. The test is a locked-cycle test where ground product is removed from test cycles and replaced by fresh feed.
