How carrier roller work

Carrier rollers are used in conveyor belts to support and move items along the conveyor. They typically consist of cylinders that rotate, allowing items to roll across them. The rollers are spaced along the length of the conveyor belt. As the belt moves, the rollers rotate, moving the items along the conveyor.

Carrier roller factory give some key points about carrier rollers:

They reduce friction

By rolling, they allow items to move more easily than sliding along a bare conveyor belt. This requires less energy and power to move the items.

They support weight

The rollers spaced along the conveyor help support the weight of items, preventing the belt from sagging.

They guide the direction

The rollers can help guide the items in a particular direction along curves and turns in the conveyor system.

They allow accumulation

By controlling the speed of the rollers separately from the belt, the rollers can allow items to accumulate in certain sections of the conveyor. The belt keeps moving but the rollers slow down or stop to accumulate the items.

Spacing is important

The spacing between rollers must be designed properly for the types of items being conveyed. Large, heavy items require more closely spaced rollers compared to small, lightweight items.

Roller material matters.

Rollers can be made of materials like steel, aluminum, polypropylene or high-density polyethylene depending on the application. Harder, more durable materials are used for heavy-duty industrial applications.

Powered or non-powered.

Rollers can operate without their own power source, simply rotating as the conveyor belt moves (non-powered). Or they can be powered using motors for more control (powered rollers). Powered rollers allow zones along the conveyor to be independently controlled.
