Rollers/Belts: Load Capacity Up to 500 kg/m

Component Specifications

Definition

Rollers are cylindrical rotating elements mounted on bearings that support and guide conveyor belts, while belts are continuous looped bands made of flexible materials that transport materials across the conveyor system. In drum conveyors, these components work in tandem to create efficient material handling with controlled speed and direction.

Working Principle

Rollers rotate on fixed axles using bearings, reducing friction and enabling smooth belt movement. Belts wrap around drive and idler rollers, using friction to transfer rotational energy into linear material transport. The drum conveyor configuration uses multiple rollers to support the belt along its length, with drive rollers providing motive force through electric motors or mechanical drives.

Materials

Rollers: Steel (carbon/stainless), aluminum, or polymer cores with rubber/urethane coatings. Bearings: Sealed ball or roller bearings. Belts: Rubber (natural/synthetic), PVC, polyurethane, or fabric-reinforced composites with various surface textures (smooth, cleated, patterned).

Frequently Asked Questions

What maintenance is required for conveyor rollers and belts?

Regular inspection for wear, cleaning to prevent material buildup, lubrication of bearings, tension adjustment, and alignment checks to ensure optimal performance and prevent premature failure.

How do I select the right belt material for my application?

Consider material characteristics (abrasiveness, temperature, chemical exposure), load requirements, environmental conditions, and compliance needs. Rubber belts offer durability for general use, while PVC/polyurethane suits food/pharmaceutical applications.
