This value was then divided by 12 to convert the hammer tip speed to feet per minute. Based on this formula and the measured motor speeds, the resulting hammer tip speeds were 10,250, 15,375, and 20,500 ft/min. Calculating tip speed allowed the results to be interpreted and extrapolated to other hammermills of varying dimensions.
The limited residence time and limited particle size for inefficient comminution were previously reported for hammer mills [61] and ball mills [55]. It was also suggested that this milling ...
