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 ...

The prediction of the trajectory of an object was assessed by a procedure that calculates the position of an object after leaving the field of vision. A ray-tracing software was produced and tested by an experimental phase. The methodology for object recognition and trajectory prediction was set-up and verified.

The 5th, 6th, and 7th editions of the Conveyor Equipment Manufacturers' Association Belt Conveyor Design Manual includes several methods to calculate the belt tension required to move bulk materials on a conveyor belt. They are beyond the scope of this short video. These methods include "historical", "basic", and "universal" methods.

The main particle mechanisms occurring within a conveyor transfer are product discharge, trajectory, impact, free-fall and chute flow (Burnett 2000). An illustration of these mechanisms is depicted in Figure 1. This paper will focus on the determination of material trajectory as it is discharged from a belt conveyor.
A conveyor designer needs to choose belt cleaners for a conveyor carrying limestone from the quarry pit. The conveyor width is 36 in and the belt speed is 420 fpm. The belt will be installed with a vulcanized splice but will be spliced mechanically during its life. Referring to the Belt Width chart, a score of "1" for the 36" width is ...
