Shaftless Vertical Conveyors

Shaftless Screw Conveyors are ideal for vertical conveying. Since they do not require a non-drive end bearing this eliminates the need for high maintenance bottom shafts and seals on a pulling shaftless vertical conveyor.   A shaftless vertical feed is obtained by directly connected pushing shaftless conveyor which optimizes layout design flexibility. Vertical shaftless conveyors are available in a single unit up to 50 feet and systems in excess of 100 feet in elevation gain.

The elimination of the shaft and hanger bearings eliminates flow-impediments found in shafted screw conveyors. This also enables a much higher fill rate resulting in slower screw speeds, more efficient conveying and consequently less wear and power usage. 

Maximum performance is achieved through close clearance between the trough and spiral. It is a space saving, extremely reliable conveying method. 

 
Custom Conveyor Corp’s open shaftless spiral design makes these conveyors ideally suitable to efficiently convey stringy, sticky waste materials that vary in size, volume, capacity or dry solids content. They work extremely clean and efficient for conveying materials such as dewatered sludge with dry solids content of 18% or greater.

Custom Conveyor Corp. engineers perform important spiral strength calculations on every shaftless application.  We utilize many spiral configurations to insure the proper compression or elongation strength is achieved for your application.  We manufacture and test all of our conveying products and systems at our 32,000 square foot plant in Rogers, MN to ensure compatibility with and integration into your plant is consistent and flawless.

CUSTOM shaftless verticals are highly efficient in:

• Power usage, space, conveyance, and equipment wear…
• Resulting in a virtually maintenance free and highly cost effective solution.
