Claims17
A conveyor pulley having a first end, second end and an axis which extends through the first end and second end, the pulley comprising:
- a drum or shaft;
- a reinforcing disk between the first end and second end, the reinforcing disk being annular and having an inner radius and an outer radius;
- a first plurality of wings that extend from the reinforcing disk toward the first end;
- and
- a second plurality of wings that extend from the reinforcing disk toward the second end, each wing of the first and second plurality of wings having a lower end, an upper end, an outer end and an inner end, the lower end being attached to the drum or shaft, the inner end being attached to the reinforcing disk between the inner radius and outer radius of the reinforcing disk;
- wherein the axis of the pulley and each wing form an angle, the angle being between about 30° and about 60° to allow material to be expelled from the pulley.

A belt conveyor system for transporting bulk materials, the system comprising:
- a conveyor belt;
- a tail section at which bulk material is loaded onto the conveyor belt, the tail section including a tail pulley around which the conveyer belt is looped, the tail pulley having a first end, second end and an axis which extends through the first end and second end, the tail pulley comprising:
- a drum or shaft;
- a reinforcing disk between the first end and second end, the reinforcing disk being annular and having an inner radius and an outer radius;
- a first plurality of wings that extend from the reinforcing disk toward the first end;
- and
- a second plurality of wings that extend from the reinforcing disk toward the second end, each wing of the first and second plurality of wings having a lower end, an upper end, an outer end and an inner end, the lower end being attached to the drum or shaft, the inner end being attached to the reinforcing disk between the inner radius and outer radius of the reinforcing disk;
- wherein the axis of the pulley and each wing form an angle, the angle being between about 30° and about 60°;
- a head section at which bulk material is discharged from the conveyor belt, the head section including a head pulley around which the conveyor belt is looped.
