Tubular troughs are used in most inclined screw conveyor applications above 20 degrees. Conveying efficiency is greatly improved because bulk materials are contained within the tubular housing and fall back is reduced. U-Troughs are Used for Conveying Bulk Materials Horizontally or on Inclines up to 20-Degrees.

Tubular Housings. Tubular housings are typically used when a screw conveyor is inclined over 15-degrees. Conveying efficiency is greatly improved with tubular housings because bulk materials are contained and fall back is reduced. Tubular housings are also used for weather-tight applications and used to hold internal pressure in a screw conveyor.
