Experimental roller mills are not generally equipped to measure energy requirements for grinding. An experimental roller mill with a computerized data acquisition system was developed to acquire power and feed rate data (Fang et al., 1995). The roll dimensions were 250 mm (10 in.) in diameter and 100 mm (4 in.) in length. The roll surface ...
