Pneumatic conveying pipe bend with raised-diamond interior pattern works like a gem

After trying many pipe bend styles, a plastic resin manufacturer finds one that's lightweight, durable, and that reduces plastic pellet degradation.

Quantum's USI Division, Morris, Ill., manufactures low-density polyethylene [LDPE] and linear LDPE [LLDPE] resins.

The finished pellets are fed through a rotary airlock into the first leg of a dilute-phase pressure pneumatic conveyor that's approximately 1,100 feet long overall.
