Conveyor Types

For centuries conveyors have played an important role in moving something from one point to another. Back before the time of Christ, the Romans constructed numerous aqueducts to serve any large city within their empire. In more modern times, the Thomas Jefferson home Monticello, was one of the first to have indoor latrines. Human waste was gravity fed down chutes to a pit in the basement. In our industrial era, conveyors of all levels of sophistication are employed by every industry segment be it agriculture, aviation, manufacturing, mining, or pharmaceutical.

There are several types of conveyors. Here are just a few:

  • Pneumatic conveyors
  • Gravity Conveyors
  • Belt Conveyors
  • Drag conveyor

Pneumatic conveyors

Pneumatic conveyors move material through a tube with air flow. They are used with small loose material such as pellets, resins, pills/tablets, shavings, chips, and etc. The EXAIR Line Vac is an example of a pneumatic conveyor.  A flow of rush of air flows into the hose dragging along with it whatever it is that you are wanting to move.

In industrial applications, the intention is to move product from dispensing point over to the point of use. In this case a Line Vac provides a simple and quick installation using the facilities compressed air as the motivational force. The simplicity of this style of conveyor lends itself to many applications from vacuuming metal shavings to moving coffee beans into a roaster.

Gravity Conveyors

Two common types of gravity conveyors are the skate wheel and roller. In the picture to the right we see an example of skate wheel conveyor feeding into a roller conveyor. The wheel and rolls have bearings in them to reduce friction thus enabling less incline.

In situations where the incline is insufficient to induce the product to move, the rollers can be powered.  Each roller is connected to a powered line shaft with a v belt.

Belt Conveyors

All of us have come into contact with this type of conveyor. They are used to move your check out items to the cashier. They are probably the most common type used throughout industry.

They come in many configurations, belt materials, some with cleats, and some as buckets that fold up as they pass over the head pulley.

Drag Link Conveyors

Drag link conveyors are a series of disks inside a tube. Each of the disks
are connected together by a tow line. The material in enclosed thus preventing outside contamination.
