Screw conveyors can be designed without a centre pipe. This type of conveyor is called a shaftless screw conveyor or centreless screw conveyor and is designed for conveying wet, sticky, sluggish products such as industrial sludges and larger irregular shaped products.

Screw conveyors can be operated with the flow of material inclined upward. When space allows, this is a very economical method of elevating and conveying. As the angle of inclination increases, the capacity of a given unit rapidly decreases. The rotating part of the conveyor is sometimes called simply an auger.

A screw conveyor is a versatile conveyor used in many process plants for the transfer of bulk solids and powders.
