Portec Angle-Flo® Technical Specifications

Angle-Flo^® Belt Conveyor

TECHNICAL SPECIFICATIONS

Frame Assembly:
The all-steel frame is fabricated using the following materials:

A. Frame sides	12 gauge (2.65 mm) steel
B. Slider bed	12 gauge (2.65 mm) steel

Welded 1/4" (6.35 mm) thick angle steel cross members provide a solid conveyor platform. 1/8" (3.18 mm) thick steel angle is welded on the lower edge of the frame side to attach floor supports.

Frame Height: Conveyors with a belt width up to 24" (610 mm) will have a 7" (178 mm) high frame and conveyors with a belt width over 24" (610 mm) will have a 9" (229 mm) high frame.

Belt Top Cover:	2-ply Black PVC
Thickness	.091" (2.3 mm)
Allowable working tension (1.3% elongation):	112 lbs./inch width (20N/mm)
Underside:	Very low friction fabric
Belt fabric:	2 ply polyester
Electrical Conductivity:	Anti-static
Seams:	Vulcanized Endless

Angle Air Bar System
The conveyor belt of most angle merge conveyors bends over a solid steel bar on the angled end of the conveyor. As the belt slides over the steel bar, the bar becomes very hot. Each time the conveyor belt stops, the hot bar damages a strip across the bottom of the belt. This greatly reduces the life of the belt and limits the belt speed and allowable operating time.

The Portec Angle-Flo® conveyor uses an air bar on the angled end of the conveyor. holes in the air bar allow pressurized air to float the belt away from the bar, keep the belt cool and to facilitate belt tracking. The Portec Angle-Flo® conveyor can operate continuously at high speeds without belt damage. the low friction air bar allows cycling conveyors to get up to speed quicker and more consistently.

Air Consumption
Air consumption can vary depending upon the belt speed and load from 6CFM @ 30 psi (2.8 cm³ @ 206 kPa) to 9CFM @ 50 psi (4.2 dm³/s @ 345 kPa).

Belt Drive System
The conveyor belt is driven by its bottom side contacting a heavy duty lagged roll drive. Contamination of the belt surface does not effect the conveyor operation. A spring- loaded take-up maintains even belt tension even through changes in loading and temperature.
