Mechanical Conveying & Belt Conveyors
Answer in brief
Mechanical conveying moves bulk solids along a defined route with driven equipment. Belt conveyors handle continuous transport, sandwich belt systems contain material between two facing belts for steep or vertical lift, and vibrating troughs move product through controlled oscillation. Route geometry, lift and material behavior decide which concept fits.

Mechanical conveying uses moving equipment to carry bulk material along a defined route. Three distinct areas sit under this heading: conveyor belt components, high angle sandwich belt conveying and vibrating trough conveying.
Belt conveyor components and maintenance
Belt cleaning systems remove material that remains on the returning belt. Skirting and transfer point sealing contain material where it enters the belt. Tracking, impact protection, fastening and maintenance tools address other parts of belt operation. Flexco, PUCEST and ScrapeTec provide the documented examples here.
High angle sandwich belt conveyors
Dos Santos International describes a sandwich belt conveyor as two facing belts that contain the carried material. This arrangement supports steep incline and vertical lift routes.
Vibrating trough conveyors
Vibrating trough equipment moves bulk material through controlled oscillation of a trough. AViTEQ lists vibrating feeders, tubular feeders, reversible trough feeders and guided arm trough conveyors within its conveying portfolio.
How to select Mechanical Conveying & Belt Conveyors
Start with the route and the material. Define the horizontal distance, lift, transfer points, required flow, material behavior and available space before comparing equipment concepts.
Selection inputs
- Material identity and verified flow behavior.
- Required capacity and operating pattern.
- Horizontal distance, lift and route geometry.
- Transfer point containment and dust control.
- Cleaning, inspection and maintenance access.
- Interfaces with upstream and downstream equipment.
Confirm performance, material compatibility and safety requirements with the supplier for the complete operating duty.

Frequently asked questions
What mechanical conveying systems are used for bulk solids
Common systems include belt conveyors, screw conveyors, chain conveyors, bucket elevators and vibrating trough conveyors. Selection depends on the material, route, lift, capacity and containment requirement.
When is a belt conveyor used
A belt conveyor is considered for continuous transport along a defined route. The belt, transfer points, support system and cleaning arrangement must suit the material and operating duty.
How can bulk solids be conveyed at a steep angle
One option is a sandwich belt system that contains material between two facing belts. The exact system must be selected for the required lift, route and material.
What is a vibrating trough conveyor
A vibrating trough conveyor moves material through controlled oscillation of a trough. The drive, trough and operating settings must match the material and required flow.
