Types of Conveyors

There are different types of conveyors. They are: flight conveyors (скребковые конвейеры), overhead (подвесные) conveyors, pneumatic conveyors, hydraulic conveyors and others.

Flight conveyors have an electric chain passing around sprockets at the head and foot ends. Flight conveyors are of several hundred feet in length.

Overhead conveyors consist of a power-propelled chain traveling at moderate speeds.

Pneumatic conveyors differ from other machines for transporting materials. The pneumatic conveyor takes more power than any mechanical conveyor. If the material is heavy, the efficiency drops sharply.

Hydraulic conveyors require less power than pneumatic conveyors.
