How it works

The basic operating principle of the Olds Elevator is very simple, however it is a whole new science. The Olds Elevator Technology reverses conventional screw conveyor design methodology employing instead a static screw inside a rotating casing.

It operates in a ‘flooded’ or ‘full bore’ flow mode, where the rotating casing and screw are filled with the material being conveyed.

Quiet in operation, the unique design delivers a flow of material that is always smooth and steady, free from the pulsations experienced with conventional screw conveyors and bucket elevators.

Fragile and difficult to handle materials can be conveyed with negligible damage. The gentle handling charateristic of the technology minimised product degradation and dust.

A variable speed drive achieves accurate and infinitely variable flow control enabling use as a volumetric feeder.
