Since screening efficiency is directly proportional to the length of the trommel, a shorter trommel screen would be needed at a smaller inclination angle to achieve a desired screening efficiency. It is suggested that the inclination angle should not be below 2° because the efficiency and production rate is unknown beyond this point.
