Similarly, the power required to produce lift can be determined using: equation4. Where: C = Conveyor capacity (kg/s) L = Lift required (m) PL = Power required for the conveyor to produce lift So, let's say there is a need for a conveyor system with a capacity of 400 TPH (or 111.1 kg/s) to produce a lift of 15 m. The power …

40-percent on inclines up to 20-degrees. A screw conveyor with U-trough and 2/3-pitch screw is sufficient for most applications. Loss in efficiency can also be overcome by increasing the speed or the diameter of the screw conveyor. Additional horsepower is required to overcome gravity and bulk material fall back. s )NCLINE"ETWEEN AND
