Belt Conveyor Discharge Trajectories

Jan 17, 2011  Over the Christmas break I've been reading "Conveyor Belt Trajectories - Comparing Predicted to Experimental Results" by Hastie and Wypych published in "bulk solids handling, Technology Special". I'm interested to see that "the Booth method provides a very good prediction of the experimental trajectories for both polyethylene pellets and corn under a wide range of belt speeds".

Trajectory is the path the material takes Martin Engineering

The path the bulk material takes as it is discharged from the delivery conveyor is called the trajectory. Trajectory is affected by the speed of the belt, the angle of inclination of the discharging belt and the profile of the material on the belt. In conventional transfer-chute design, the trajectory is plotted and used as a starting point for ...

Belt Conveyor Transfer Points

May 08, 2019  The simplest discharge from a conveyor belt is to let the material pass over a terminal pulley. In most conveyor installations, the troughed belt goes through a transition section onto a flat pulley. The time required must be short enough to prevent the material, originally contained in the trough from spilling over the edges of a flat belt.
