Screw conveyors and feeders are the backbone of controlled material movement. Selecting the right configuration ensures predictable flow, reduced wear, and long-term reliability.

Designing a screw conveyor is never one‑size‑fits‑all. Every application demands attention to:

• Material characteristics — size, weight, abrasiveness, temperature
• Rate & speed requirements
• Incline angle
• Trough style & mating equipment
• Flighting geometry
• Drive package torque & speed control

These variables determine how efficiently material moves—and how long your equipment lasts.

The motor and reducer drive package is the heart of the system. Proper sizing ensures the conveyor can start under load, maintain consistent speed, and deliver the torque required for dense or sticky materials.

The trough (housing) determines how material enters, moves, and exits the conveyor.

• U‑troughs are standard for most applications.
• Rectangular troughs extend life when handling abrasive materials.
• Oversized troughs (e.g., 12" screw in a 14" trough) allow material to ride on itself, reducing wear.
• Drop‑bottom troughs simplify cleanout when sanitation or product changeover is required.

Flight geometry determines how material is metered and conveyed. CSC recommends:

• Short pitch at the inlet to prevent compaction
• Full pitch after the inlet for smooth, non‑compacted flow
• Varied pitch for slotted inlets (48"+) to draw material evenly from hoppers
• Tapered screws as an alternative—though they may retain material in the trough

High Temperature Materials

For materials above 300°, CSC incorporates a heat isolation chamber to protect the reducer and simplify installation.

Steep Inclines

For inclines above 25°, tubular trough screw conveyors maintain flow and prevent fallback.

Abrasive Materials

• Hard‑surfaced screws
• Oversized or rectangular troughs
• Air‑purge seals to prevent leakage
• Explosion protection per NFPA 68 when required

Bucket elevators provide vertical conveying for a wide range of materials. Choosing the right style ensures efficiency, reduced degradation, and long equipment life.

Centrifugal Elevators

Best for: fine, free‑flowing materials

• Operate at 250–300 fpm
• Use centrifugal force to discharge material
• Ideal for high‑throughput applications

Continuous Elevators

Best for: fragile, heavy, or large‑lump materials

• Operate at ~125 fpm
• Gentle handling minimizes degradation
• Excellent for materials that must remain intact

Belt Type Elevators

• Ideal for abrasive, dry, free‑flowing materials
• Limited in high‑temperature applications

Chain Type Elevators

• Handle heavier loads and greater heights
• Suitable for high‑temperature materials
• Use sprockets for positive alignment

• 10”×36”
• 16”×40”
• 16”×48”
• 24”×48”
• 24”×54”

Explosion protection available per NFPA 68 for sensitive materials.

The application of Flexible sidewall conveyor is dependent on many factors as outlined above.

Because of their special design these type of belt are expensive to manufacture along with the associated pulley and deflection wheels.
