The impact of attrition ball-mill pretreatment on food waste particle size, soluble chemical oxygen demand (SCOD), biochemical methane potential, and microbial community during anaerobic digestion was investigated based on milling speed and time. The uniformity of particle size improved with increasing milling speed and time. The SCOD of the pretreated samples …

Abstract. Talc powder samples were ground by three types of ball mill with different sample loadings, W, to investigate rate constants of the size reduction and structural change into the amorphous state.Ball mill simulation based on the particle element method was performed to calculate the impact energy of the balls, E i, during grinding.Each rate constant correlated with …
