The new test, called JK Bond Ball Lite (JK BBL), is a locked cycle grindability test
conducted using a standard laboratory Bond ball mill with the same steel ball
These "errors" in the Bond test are often underappreciated in design, and the results are discussed in the context of implications for mill sizing. Other major factors that drive ball milling efficiency, which are not accounted for by the Bond equation but are strongly evident in the JKTech database, are also presented.
