Spiral elevators are an incredibly efficient conveying technology. These machines elevate products vertically inside a helix with a combination of oscillation, frequency of vibration and stroke length.
Our Spiral elevators are compact helical towers that allow plastic granulate to be vertically conveyed within a small footprint. Traditionally material would be elevated with a belt conveyor at approximately 45° increasing the footprint of your plant by the height of elevation. Now, thanks to spiral conveyors, we can move material up to a height of 20m in as little footprint as 2m2.
Due to the smooth harmonic vibratory motion, these intuitive machines produce a micro-throwing motion that moves the product without causing product degradation. The kinetic energy is provided by two unbalanced motors at the top of the helical tower that creates an oscillating vibration. These forces move the particles up the spiral and into the next stage of processing.
The helical shape of the spiral elevator produces a large dwell time in comparison with its footprint making it an ideal place to add additional functionality if appropriate for the application. This is an extremely versatile machine and can be adapted to heat, cool, dry and dewater granulate.
Manufactured completely out of stainless steel and fully welded, our spiral elevators are perfect for conveying plastics as well as metal turnings, foodstuffs and chipped timber. These machines are simple to install and due to the reduced number of moving parts are simple to maintain, reducing downtime.
At Rotajet we pride ourselves on producing solutions not just machinery. That’s why we conduct full trials on any non-standard material to ensure your process requirements match the capability of the equipment at our dedicated test facility in West Yorkshire.
