Wing Pulley
|
Where abrasion and excessive build up conditions exist, the “HDW” pulley with self- cleaning action provides an excellent alternative to conventional drum style pulleys.
"HDW" Heavy Duty Wing Pulley
Pulley and belt life is extended by the self- cleaning action employed by the PPI “HDW” Heavy Duty Wing Pulley. Individual all-steel wings and gussets expel excessive buildup of material from the area of belt contact which enhances traction and reduces abrasion of both belt and pulley
Note: Larger diameters are built as an E-wing, i.e. with an end disc.
"MDW" Mine Duty Wing Pulley
Demanding wing pulley applications call for PPI Mine Duty Wing Pulleys. Designed after the “HDW” Heavy Duty Wing Pulley, Mine Duty Wing Pulleys feature the same self-cleaning action that reduces excessive material buildup. The extra heavy duty construction reduces the possibility of metal fatigue and enhances the dependability of the PPI “MDW” Pulley. A 3/4" x 3/4" reinforcement ring is used on all “MDW” Pulleys. Available with various hub and bushing systems.
Spiral Wing Pulley
The PPI Spiral Wing Pulley is formed by a flat bar helically wound towards one another, welded to all steel wings, with intervals between them to allow excess material to discharge to the side of the conveyor. Although similar to a standard wing pulley, this design permits continuous pulley contact with the belt during rotation which eliminates excessive noise and vibration without sacrificing self-cleaning action. Available with various hub and bushing systems.
