Understanding Belt Conveyor Systems

04th January 2022

Load Capacity per Unit Length

Manufacturers will offer this attribute in cases where the belt conveyor will be built to a custom length to permit users to determine loading margins.

Maximum Load Capacity

Associated with Load Capacity per Unit Length, this value can be stated for fixed length, purpose-built belt conveyors. This can also be known as flow rate.

Belt Conveyor System Speed/Rated Speed

Belt conveyors are typically rated in terms of belt speed in ft/min. while powered roller conveyors described the linear velocity in similar units to a package, carton, etc. moving over the powered rollers. Rated speed applies to apron/slat conveyors and drag/chain/tow conveyors as well.


Throughput measures the capacity of belt conveyors that handle powdered materials and similar bulk products. It is often given as a volume per unit time, for instance, as cubic feet per minute. This attribute applies to bucket, pneumatic/vacuum, screw, vibrating, and walking beam belt conveyors.

Frame Configuration

Frame configuration refers to the shape of the belt conveyor frame. Frames can be straight, curved, z-frames, or other shapes.

Drive Location

Drives can be located in different places on belt conveyor systems. A head or end drive is found on the discharge side of the belt conveyor and is the most common type. Center drives are not always at the actual center of the belt conveyor, but somewhere along its length, and are mounted underneath the system. They’re used for reversing the direction of a belt conveyor.
