Recycling
L-R: John Ellis-Plant Manager with Dermot Donaghy of Blue Scotland
The processing operation:
Currently processing between 80-100tph the new MRF is served by a Terex Fuchs MHL 331 Material Handler which feeds the pre-sorted waste into an inclined heavy-duty GK grizzly feeder. This grizzly splits the waste with the +150mm oversize going forward up an inclined conveyor into a 7-bay picking station. Following picking, any residual material passes under a magnet where any ferrous is removed to the side with the rest passing under an air knife which separates the lights to the side with any aggregate dropping below into a bay.
Any fraction -150mm is fed to the right which passes under a magnet where ferrous is removed by an overhead magnet with the rest fed into an 8m3 feed hopper. Material is then fed onto an inclined covered conveyor onto the top deck of the Spaleck® screen which separates the 10mm fines to stockpile with the 40-150mm fed forward to the 4-bay picking station
passing under a blower to remove the lights en-route. Here wood, cardboard, plastics and non-ferrous material is picked and dropped to the bays below. The remaining material again passing under a magnet to remove the ferrous with the remainder finally passing under a Typhoon 1500 air density separator to remove any remaining lights with any aggregate dropping to the bay below.
Dermot Donaghy – Sales Manager, Blue Scotland, commented, ”It’s a very compact arrangement which had to fit into a tight footprint, but we achieved this by elevating the feed end. This has also made the loading more efficient as the plant can now be fed easily by one material handler. The two picking lines have also allowed more picking bays to be featured with an element of future proofing by adding more
men and increasing throughput, making the whole operation even more efficient.”
The future:
The bespoke design of the new MRF at Bonnybridge is providing a more efficient operation on a daily basis, by increasing the waste processing capacity and specifically enhancing the cleanliness and quality of the end-products created during the recycling process.
With the in-built future proofing the new versatile MRF will supply the daily demands of Central Demolition for some time with the added confidence of total support from Blue Scotland.
