The goal of this work is to create an equation to adjust a Bond ball mill work index from one P 80 basis to another. The proposed model consists of two components, the variable coefficient that is determined from a specific work index determination and a fixed exponent determined by a calibration procedure.
work indices for the AG/SAG mill and ball mill can be re-organised as [7] and [8], where B'Wio and A'Wio are the corrected operating work indices and WAG/SAG, WBM are the respective power draw of AG/SAG and ball mills. Note that the ball mill operating work index is applied only on the portion that needs the additional grinding (Q2),
This test determines the Bond Ball Mill Work Index, which can be used with Bond's Third Theory of Comminution to calculate net power requirements for sizing ball mills. The test is a closed-circuit, dry grindability test is run in a standard ball mill, and can be performed at sizes ranging from 595 mm to …
