Energy consumption per ton solid biofuel,the rate of qualified molded biofuel,mechanical durability and particle density were used to evaluate the effect of changing clearances between rolls and die, spindle speed and diameter of die orifice. The results indicated that clearances between rolls and diejusthad an effect on the rate of qualified molded biofuel, and the best optimal value was 0郾2 mm, the energy consumption and particle density reducing by increasing of the spindle speed,bigger diameter of die orifice would bring about higher p
