Once a belt conveyor is confirmed as the right conveying method, the next decision is configuration — and this is where projects go wrong if it's treated as a formality rather than an actual spec decision. Troughed, flat, inclined, and cleated belts each suit a different combination of material, throughput, and layout.
Flat Belt
A flat conveying surface, typically used for horizontal transfer of packaged or bagged product rather than loose bulk material. Maximum practical incline is limited — around 5° — beyond which product on a flat belt tends to slide back rather than being carried.
Best fit: horizontal transfer of bags, cartons, or unitised product between fixed points; lower-capacity general transfer duty.
Where it falls short: loose bulk material (powder, granules) isn't well contained on a flat surface, and it can't handle meaningful incline.
Troughed Belt
The belt runs over idler rollers set at an angle, forming a trough shape that contains loose bulk material far better than a flat surface. This is the standard configuration for higher-capacity bulk material transport — ENZAC's range covers throughput up to 500 t/hr depending on belt width (300–2,000mm) and speed (0.1–3.5 m/sec, VFD-controlled).
Best fit: bulk powders, granules, or aggregate at meaningful throughput; general-purpose bulk transfer where incline is moderate (18–22° typical).
Where it falls short: troughed belts need more width and support structure than a flat belt for the same footprint, and containment — while better than flat — still isn't fully enclosed.
Inclined Belt
Either flat or troughed, run at a steeper angle (up to 20–30° for standard configurations) specifically to elevate material as part of the transfer route — moving product between floor levels or up into a hopper or process inlet.
Best fit: any transfer route that needs to gain height, not just move horizontally.
Where it falls short: incline angle has real mechanical limits before material starts sliding back down the belt, which is where cleated designs take over.
Cleated / Chevron Belt
Adds raised cleats or chevron patterns across the belt surface to physically carry material up steeper inclines — up to 45° on ENZAC's range — well beyond what a plain belt can hold without slippage.
Best fit: steep-incline transfer where floor space for a long, gently-angled run isn't available.
Where it falls short: cleats add cost and complicate cleaning/changeover compared to a plain belt; not needed if a gentler incline is achievable in your layout.
Decision Table
| Requirement | Flat | Troughed | Inclined | Cleated/Chevron |
|---|---|---|---|---|
| Bagged/unitised product, horizontal | ✓ Best fit | Overkill | N/A | N/A |
| Loose bulk material, high capacity | Poor containment | ✓ Best fit | Combine with troughed | Combine with troughed |
| Moderate incline (up to ~30°) | Not suited | ✓ Suited | ✓ Standard | Overkill unless steeper needed |
| Steep incline (up to 45°), tight footprint | Not suited | Not suited | Limited | ✓ Best fit |
Drive and Belt Material Still Need Matching to Your Product
Configuration answers the "what shape" question — drive type (head or tail drive, geared motor with VFD control) and belt material (rubber, PVC, food-grade polyurethane, stainless steel mesh, or anti-static variants) still need to match your specific product and environment. A conveyor with the right trough shape but the wrong belt material for a food-grade or combustible-dust application is still a misspecified conveyor.
Review the full Belt Conveyor specification range — widths, speeds, incline capability, and material options — before finalising configuration for your client's scope.
