Fixed Carrying Troughing Set
The fixed carrying troughing set is a stationary conveyor support assembly designed to carry and shape the conveyor belt into a trough profile during material transport. It typically consists of three idlers (one horizontal center roller and two inclined side rollers) mounted on a rigid steel frame. The troughing angle, commonly 20°, 30°, or 35°, is selected based on belt width, material characteristics, and conveying capacity requirements.
The assembly is engineered to provide continuous belt support, ensuring uniform load distribution and minimizing belt sag between stations. The fixed configuration means the idler frame is securely mounted to the conveyor structure without articulation, providing stable and reliable operation under constant load conditions.
Key Design Elements
Configuration: Typically consists of a 2-roller arrangement mounted on a rigid,
non-adjustable frame.
-
Trough Angle: For small grains, a 20° or 35° angle is standard to provide a
balance between capacity and belt stress.
-
Speed Limit: Capped at 2.5 m/s to minimize vibration and prevent material
"boiling" or spillage of fine grains.
-
Material Suitability: Ideal for non-abrasive bulk materials like wheat, corn, or
small seeds, where high-impact resistance is not required.
-
Frame Construction: Usually made of lighter gauge pressed steel or cold-
formed channels, as it does not need to withstand the heavy shock loads of
mining or large rock transport.
Rollers are equipped with sealed bearings to ensure smooth rotation, reduced friction,
and extended service life in demanding industrial environments. Frame construction is
typically fabricated from high-strength structural steel with protective surface treatment
such as galvanization or powder coating to resist corrosion and mechanical wear.
The fixed carrying troughing set plays a critical role in maintaining belt alignment,
reducing material spillage, improving conveying efficiency, and extending the overall
lifespan of the conveyor system.
