Scottish solution equips itself for reclamation
A recycling plant is reclaiming up to 95% from the raw materials it is receiving from Scotland and North-east England thanks to cutting-edge equipment
Central Demolition, based in Bonnybridge in Stirlingshire, has invested in a new recycling plant and achieved “excellent results” in volume reclamation of recyclables and end-product quality. The company has added to its existing recycling plant and created a tandem configuration of specialist recycling machines to process large volumes of C&D waste for the production of saleable reclaimed materials. It uses a combination of General Kinematics, Powerscreen and Kiverco equipment, sourced from Blue Machinery Scotland.
Central Demolition says it is reclaiming 90-95% from the thousands of tonnes of raw waste material at its Bonnybridge recycling station, which are brought in from its own demolition and site clearance contracts as well as materials received from other sources throughout Scotland and North-east England. It specialises in demolition and dismantling, licensed asbestos removal, earth moving, site clearance, plant and tipper hire, landfill and recycling.
The company, which was formed in 1993, has evolved to become a national organisation in its specialist fields. It says it has always placed great emphasis on investing in the best possible plant and equipment for its operations, and that it
has enjoyed a long and beneficial working relationship with Blue Machinery Scotland when it comes to sourcing recycling plants.
One-stop-shop meets recycling needs
Managing director Ross Craig says: “We look on Blue Machinery Scotland as our one-stop-shop for all our recycling needs and their range of distributorships allows us to mix and match equipment to suit our processes. Blue Machinery is an expert in its field and we know we can rely on their skills right from the planning stage through to installation and commissioning. Additionally, we find that their after-sales product support through Spares UK is prompt and efficient, keeping any downtime to an absolute minimum.”
Central Demolition has installed additional recycling machines to enhance primary and secondary reclamation of recyclables from C&D waste. The new plant array consists of a Grizzly separator from General Kinematics, a conveyor and a five-bay picking station system from Kiverco. All of these lead to a General Kinematics de-stoner and a Powerscreen 615 trommel, already owned by Central, and which carry out the final secondary screening and stockpiling.
The compatibility of these different marques has allowed Central Demolition to configure the installation so that the processing sequence is as effective and automated as possible, with a potential for further add-on equipment.
The incoming raw waste is first pre-sorted by the GK Grizzly separator. This produces a bigger mid-size of 180mm, but also carries out this primary process automatically. The resulting material is then conveyed to the under-cover picking station where operatives are able to carry out manual sorting to the designated bins in a safe and productive environment.
From here, the final stages are through the GK de-stoner and Powerscreen trommel 615, which are separating, screening and stockpiling as a secondary process. The de-stoner works in conjunction with the trommel to clean up the mid-size material after the inert fines have been removed at 10mm. The resulting clean 10mm-180mm is then combined with the clean hardcore from the primary recycling stage for crushing by a TEREX Pegson XR400 mobile crusher to produce recycled aggregates.
From the large daily tonnages of co-mingled waste that come into its Bonnybridge recycling station, Central Demolition is able to reclaim an increased range of clean saleable materials, including ferrous and non-ferrous metals, recycled aggregates in various specified sizings, composting, soil improvement and landfill cover materials, board, timber and paper. Volumes of non-recyclable materials are minimised by the processes.
