Vertical Screw Conveyors

KWS Vertical Screw Conveyors use a very efficient method for elevating a variety of bulk materials at very steep inclines or completely vertical. The compact design allows for the vertical screw conveyor to fit into almost any plant layout. With a minimum number of moving parts, the vertical screw conveyor is a cost-effective and dependable component of any bulk material handling process.

Advantages of Using Vertical Screw Conveyors

KWS Design, Engineering, Manufacturing
Olds Elevator

Olds elevators are ideally suited to elevate a broad range of bulk granular and powdered materials vertically. Even dense, abrasive materials are easily elevated by Olds elevators. Olds elevators are mechanical, there are no pneumatics involved. Olds elevators employ a Static Screw and a Rotating Casing with intake scoops attached. The lower end of the rotating casing is situated in a feed hopper. As the casing rotates the intake scoops gather material from the bottom of the feed hopper and feed it into the casing.


Olds Elevator

Olds elevators have only 1 moving part in contact with the material being conveyed: the rotating casing with attached intake scoops. All bearings are external to the product zone. Many current vertical elevation needs are met with Bucket Elevators.

Bucket elevators are simple, inexpensive mechanical elevators that are ubiquitous in the bulk material handling industry. They can also be maintenance-intensive. Bucket elevators have many moving parts, most of which are in the product contact zone of the elevator. They also are known for generating significant dust clouds within their housings, often potentially explosive dust clouds waiting only for a spark to ignite. Olds elevators inherently eliminate the risk of dust explosions by their operating principle.
