Conveyors and Their Major Types

A conveyor can be defined as any piece of equipment that is used to move or transport material over a fixed path. Conveyor system is being put to use since the early 20th century. Conveyors are popularly called the backbone of the material handling field. They allow quick, efficient and effective transportation of a wide variety of materials of all shapes and sizes.

Conveyors can be used in the following different cases:

  • When there is a need to move materials frequently between fixed points.
  • When there is a need to move material over a specific fixed path.

Types of Conveyors

There are different types of conveyors depending upon the requirements. These are as follows:

  • Chain Conveyor

Chain Conveyor can be defined as the one which uses one or more endless chains on which loads are carried directly. In a chain conveyor,  parallel chain configuration is used to transport pallets. Further, vertical chain conveyor used for continuous high-frequency vertical transfers.

  • Roller Conveyor

Roller conveyor can be further classified into two categories i.e. Powered (or live) conveyor or non-powered (or gravity) conveyor. For using Roller Conveyor there is a precondition that materials must have a rigid riding surface. Further, a minimum of three rollers must support smallest loads at all times.

  • Bucket Conveyor

Bucket Conveyor can be defined as the one which is used to move bulk materials in a vertical or inclined path. In this conveyor, buckets are attached to a cable, chain or a belt. Finally, the buckets are automatically unloaded at the ending of the conveyor run.

  • Pneumatic Conveyor

A Pneumatic conveyor is the one which can be used for movement of both bulk and unit materials. In this, air pressure is used to convey materials through a system of vertical and horizontal tubes. A great advantage in this is that it is quite easy to implement turns and vertical moves since the material is completely enclosed.

  • Chute Conveyor

Chute Conveyor is used to link two handling devices. It is also used to provide accumulation in shipping areas. Further, it is very inexpensive.
