Since there is no center pipe to transmit torque, the shaftless spiral is designed to handle the full-motor torque load of the drive unit. Additionally, since the shaftless spiral has no center pipe for support, replaceable trough-conforming liners are used to evenly support the entire length of the rotating spiral. 5/8" THK.

A 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. Inclined Screw Conveyor capacities can be increased over ...
The formula used to calculate the Screw Conveyor Flow Rate is as follows: Q = 60 * π/4 * D^2 * S * N * a * d * C. Where: Q = Flow Rate (m^3/h) D = Diameter of the screw conveyor (m) S = Pitch of the screw conveyor (m) N = RPM (Revolutions per minute) a = Loading ratio (Percentage of screw cross-sectional area filled with material) d = Density ...
