Advantages & benefits
- energy and space-saving vertical conveying that's gentle on the material
- low-maintenance continuous operation
- easy-to-clean, hygienic design
- natural cooling of the bulk solid during the conveying process thanks to long dwell times
- bulk solids cooled either directly by air or indirectly by water through the use of double bottom or laser-welded Thermplate® bottoms as the spirals
- bulk solids heated/dried either directly by air radiators or indirectly by water or thermal oil through the use of double bottoms or laser-welded Thermplate® bottoms as the spiral
Construction
The main components are:
- Spiral top from standard stainless steel or special purpose steel with single or double bottoms
- The infeed plate and spiral are available as reinforced, plastic-injected versions upon request.
- extremely heat-resistant version (conveyed material temperature up to approx. 900°C) possible upon request
- drive gear with unbalanced motors (the spiral conveyor can be executed with the drives at the top or bottom, depending on requirement)
- stationary or mobile version
- open or closed version (closed version with resonant cover or stationary housing)
Selection
The dimensioning of the spiral conveyor depends on:
- conveyed material
- flow rate
- required delivery height
- process requirements (cooling or drying etc.)
- application conditions
- available space
Key figures
- effective delivery height: up to 8,000 mm
- spiral diameter: up to 1,500 mm
- flow rates: up to approx. 30 m3/h, depending on conveyed material
- drives: 2 unbalanced motor
