Frequently Asked Questions

Recycling and waste management operations typically use spiral elevators, vibrating feeders, vibrating screens, compaction tables, and decline conveyors to move, sort, screen, and elevate dry recyclables between processing stages. Spiral Elevator Limited manufactures all of these as UK-built systems designed specifically for the demands of continuous recycling line operation.

A spiral elevator moves bulk material vertically along a helical flight path using controlled vibration. In recycling plants, this allows plastic flake, glass cullet, granulate, and mixed dry recyclables to be elevated between processing levels without the belts, chains, or nip points that cause wear and maintenance problems on conventional conveyors.

Yes. An air cooling spiral elevator channels controlled airflow along the helical flight during vertical transfer, reducing material temperatures significantly before the product reaches bagging or silo filling. Spiral Elevator Limited manufactures air cooling spiral elevators for recycled plastic processing lines in the UK. Get a free quote today.

A screening spiral elevator integrates size classification directly into the vertical conveying path, removing out-of-specification fines during elevation without a separate sieving station. This reduces equipment count, floor space, and transfer points on a recycling line.

Vibrating feeders meter material from tipping floors and infeed hoppers at a steady, controlled rate, eliminating the surge loading that disrupts optical sorters, magnetic separators, and screening decks. Consistent burden depth across separation equipment directly improves recovery rates and bale purity.

Vibratory conveying equipment using abrasion-resistant steel construction with no belts or chains in the product path is best suited for glass cullet. Spiral Elevator Limited supplies vibrating screens, feeders, and decline spiral elevators built to handle abrasive and irregular materials without the accelerated wear that affects conventional belt conveyors.

Spiral elevators from Spiral Elevator Limited rise up to 12 metres in a footprint as small as 1.8m², making them well suited to recycling facilities where floor space for primary sorting and baling equipment is at a premium.

Yes. Enclosed tube feeders and covered spiral elevator designs contain lightweight and dusty materials during transfer, reducing airborne dust at the transfer point. This lowers housekeeping burden, reduces fire risk with certain materials, and improves air quality in the facility.

A vibrating compaction table settles and densifies recovered material such as plastic flake, granulate, or shredded recyclables during IBC or bulk bag filling. This gives consistent fill weights, reduces air voids, and lowers the number of containers needed per tonne of recovered product.

Yes. A cooling or dry spiral elevator gives washed plastic flake the dwell time and airflow it needs during elevation to arrive at the next processing stage surface-dry and free-flowing. This reduces downstream energy consumption and blockage risk in mills and blending equipment.
