Fast test method for the determination of the grindability of fine materials mill dimensioning demands the investigation of the grindability of fine materials. One of the main aims of
Determining the Bond work index is a standardized method for characterizing the comminution performance of mineral samples. CEMTEC uses this method for designing rod and ball mills. Comminution performance, just like the desired comminution step as well as the production capacity, is crucial for determining which mill size is required.
Abstract. The paper covers a selection of grindability tests described in literature for the characterization of the comminution behaviour of mineral matter down to a minimum particle size of the comminution product of approximately 0.02 mm.

International Journal of Emerging Technology and Advanced Engineering593 Кб. Different C++ programmings were written to compute energy requirement, work input and grindability for the ball mill using the above mentioned systemThe results for the Bond work index grindability thus obtained may differ substantially with different standard Bond ball mills (Kaya et al., 2003).
Then, HGI (Hardgrove grinding index) is calculated and expressed in °H. The method was designed for grinding coal, but it later expanded to other materials as well . Another method is the Zeisel method, which was invented in 1953 and is based on Hardgrove. It uses a similar apparatus but operates at 100 to 200 mill revolution instead of 60.
