10th European Conference on Coal Research and its Applications Bond Index & Hardgrove Grindability Index Tests for Biomass & Coal Author: Orla Williams, MEng CEng MCIBSE Co-Authors: Dr Carol Eastwick, Prof Ed Lester, Dr Donald Giddings,
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.
The standard Bond grindability test is a closed-cycle dry grinding and screening process, which is carried out until steady state conditions are obtained (Bond, 1961, Yap et al., 1982, Magdalinovic, 1989).
