Vibratory Spiral Elevators: Equipment Applications and Manufacturing Details

Vibratory Spiral Elevators are coil shaped vibratory conveyors which are used to elevate or softly de-elevate material. Common applications include: Material that is too abrasive for screw conveyors; Another process such as cooling or heating is required during transportation; Easy access for cleaning is required; Hygienic surfaces are required. For example we can offer the following:

a. Natural cooling takes place due to the long retention time. Increased cooling can be obtained by
  using larger diameter spiral bodies or by introducing a "blown air system" (ambient or chilled).
b. Twin track spirals are available.
c. Spirals can be totally enclosed i.e. when handling very fine powders.
d. Spirals can be made in stainless steel or mild steel.
e. Curved or flat flights are used depending on the type of product being elevated and either profile
  can be corrugated.

Due to a small horizontal footprint and large travel distance, Vibratory Spiral Elevators are often used to either heat or cool material. Holes can be drilled in the central tube and hot (or cold, depending on process) air can be passed through to assist the product to reach desired temperatures. Liners can be installed on the curved trough surfaces to achieve different goals:

Polyurethane liners to provide protection from wear and prevent material from sticking.
Teflon can be sprayed which also provides wear protection and minimises material adhesion.
Hard wearing steels can be bolted or welded to an extremely hard wearing surface.
Rubber, either securely fixed or live, will greatly reduce the amount of material that will stick to the trough surface.
