When manufacturing plants need to transport and process a product, they often have to rely on a conveyor, and whether it’s a vibrating conveyor or a conveyor belt, traditional conveyors take up a large footprint within the building. Especially when the conveying needs to move vertically, as adding an incline to a standard conveyor can greatly increase the distance needed. To fix this processing issue, Carrier Vibrating Equipment developed and has been constantly improving their vibrating spiral elevator design.
The unique design of a spiral elevator means that bulk solids can be elevated and processed within a small footprint, using minimal amounts of energy. The design is low maintenance and prevents material from spilling, caking, or jamming in moving parts. The spiral elevator can be designed to fit into current production line layouts, making for easy installation.
Carrier vibrating spiral elevators can be custom designed to be any size needed, up to 11 feet wide and 60 feet tall. The flights of the elevator can be made with metal alloys or stainless steel and plasma or Teflon coated, allowing it to be USDA food and dairy grade or able to handle material up to 1500 degrees Fahrenheit.
In addition, the flights can be built using custom designed decks to further process while the material is being transported, saving time and energy on the production line.
Cross Deck
In this design, a hole is cut on the center tube and heated or cooled air is blown through the center tube, where it is directed down onto the flights by directional baffles. The air mixes with the material while it is being conveyed, and the vibrating motion means each particle surface is dried equally.
Thru-Deck
Heated or cooled air is forced through the center tube where it is sent out into a double-deck flight. The top deck of the flight has a perforation or screen specifically for the material being conveyed. The air is blown up through the perforated plate or screen, bringing it into contact with the material as it is being conveyed.
Water Cooling
This design uses a double decker design as well, but water is sprayed on the solid underside of the top deck, which causes an indirect cooling of the material being processed on the spiral elevator.
Combination Water/Air
This uses a combination of air blown and directed over the material with the use of a baffle, and water sprayed on the underside of the double decked design. This helps to process the material much faster if it needs to undergo a very quick temperature change.
Scalping
The conveying troughs can be designed with scalping screens to separate lumps or fines from the material, and for dewatering liquid based materials.
The vibrating spiral elevators can be enclosed with a shroud to control air flow and reduce dust or potential contamination.
