Screw conveyor

Screw conveyors in modern industry are often used horizontally or at a slight incline as an efficient way to move semi-solid materials, including food waste, wood chips, aggregates, cereal grains, animal feed, boiler ash, meat, bone meal, municipal solid waste, and many others.

The helical rotates inside a long metal tube, moving the grain upwards.

His grain mover employed a screw-type auger with a minimum of moving parts, a totally new application for this specific use.

The flexible nature of the auger wire allows feed or other materials to change elevation and move at angles.

The first centerless auger was patented by Eldon Hostetler and Chore-Time Equipment in the context of this application.

[4] [5] Various other applications of the screw or auger conveyor include its use in snowblowers, to move snow towards an impeller, where it is thrown into the discharge chute.

This method emulsifies the fat in beef to soften hamburger patties and is also used to produce a wide variety of sausages and loaves.

Augers are also used in some types of pellet stoves and barbecue grills, to move fuel from a storage hopper into the firebox in a controlled manner.

[9] Following similar principles to the conventional screw conveyor, the Olds elevator can lift bulk materials efficiently.
