WebbA standard Screw Conveyor inclined 15° upward will carry 75% of its rated horizontal capacity. At an inclination of 25°, a standard conveyor may only handle 50% of its horizontal capacity. These are estimated figures and will vary with the characteristic of the material being handled. WebbFp= Paddle Factor (CEMA Table 3.4) The total horsepower requirement is calculated as the sum of these two factors allowing for an overload factor and the overall drive efficiency. E= Drive Efficiency (CEMA Table 8.1) Fo= Overload Factor (CEMA Figure 3.1) Hence you have the required horsepower for the conveyor in question.
WebbSince for bean, corn and sugar densities are different, the power calculation, diameters and capacity according to the capacity are discussed in graph form. If we keep same diameter to deliver required capacity for all types of percent loading then rpm required for screws goes on increasing.
