What is a Conveyor?

A conveyor is a mechanical device utilized for the transportation of materials from one location to another. According to the American Society of Mechanical Engineers, a conveyor is defined as a “horizontal, inclined, or vertical apparatus for moving or transporting bulk materials, packages, objects, or passengers along a path predetermined by the device's design.” A crucial aspect of this definition, which distinguishes conveyors from other material handling equipment, is their ability to transport products along a path that is "predetermined by the design of the device." This characteristic is common to all types of conveyors, regardless of their specific application, industry, or sector. While many conveyors, particularly those used in sorting systems, can redirect products in multiple directions, all these routes are predetermined.

Conveyors find applications across various sectors, including industrial, commercial, retail, agriculture, and mining. They are also increasingly being adopted in the hospitality and construction industries.

The Basic Components of Conveyors

Most conveyors consist of three fundamental components: a frame or belt support, a drive mechanism, and one or more idlers.

The most prevalent type of conveyor, in its simplest form, is the end drive belt conveyor, commonly seen at grocery store checkout counters. This configuration includes a frame with a driven pulley or drum at one end and an idler pulley or drum at the opposite end, with an endless belt looping around both pulleys and the frame. Typically, the driven pulley is powered by an external electric motor.

However, there are variations to this basic conveyor design.

Conveyors can transport products in a straight line, either horizontally or vertically, and can also be designed with corners or radius sections to facilitate movement in two or three dimensions.
