📐 Inclined Transport (Inclination 10°-45° Derating Factor 0.90 to 0.35, Short Pitch Flights)

Inclined Screw Conveyor Angle Derating Calculator

Calculate CEMA steep inclination capacity derating factors ($CF = 0.90 ext{ at }10^circ ightarrow 0.65 ext{ at }20^circ ightarrow 0.35 ext{ at }45^circ$) for upward sloping screw conveyors: specify short-pitch flights ($2/3 ext{ or }1/2 ext{ pitch}$) and tubular enclosed housings to prevent severe material fallback slipping, and bulk solids handling yields.
