New BlueMAC MRF installed for Murray Browns
Company processing more C&D waste thanks to new bespoke materials recycling facility
NORTH Yorkshire-based Murray Browns have been providing services in recycling, waste-management and skip hire for more than 40 years. The ever increasing volumes of construction and demolition (C&D) waste materials that are being recycled by the family-owned business at its waste treatment centre, in Flixton, necessitated the design, manufacture and installation of a bespoke materials recycling facility (MRF) to replace a old small recycling plant.
Murray Browns, therefore, approached Blue Machinery Central and BlueMAC to help them find a tailor-made MRF solution. James Brown, co-owner of the waste-management firm, explained: ‘We’d been to see some of the first BlueMAC MRFs operating in London and were extremely impressed by the design, build quality and performance.
‘What we saw and heard from the owners of the plants convinced us that a BlueMAC system was the best option and, of course, our long relationship with Blue Machinery Central made the choice that much easier. We are also aware of Blue’s industry leading after-sales service and spares back-up and this too was another positive influence on our decision making process.’
The BlueMAC MRF for Murray Browns has been designed not only to produce the required specific clean saleable recycled products but also to fit seamlessly in the seven-acre site and allow materials handling to be carried out safely and efficiently around the new plant.
Material flow is continuous during the working day, with incoming C&D waste being conveyed and processed through a series of compatible, linked machines, including two bespoke picking stations and a fines clean-up line. A large feed hopper receives the waste with an incline conveyor feeding the prime screening trommel, which separates to 50mm.
The resulting fines are collected beneath the trommel drum and then conveyed to an IFE flip-flow screener, which is preceded by an overband magnet to extract ferrous metals. The screener produces smaller fines to 10mm with any oversize material passing on to a General Kinematics Destoner, which separates the heavies from the lights, the latter being blown by an air knife and collected in a lights cage.
The residual heavy material is collected from this process and conveyed to a single-bay picking station for manual separation and selection, which removes required materials via a chute to a concrete storage bay below.
Oversize material from the trommel is conveyed to a second picking station featuring six bays, where recyclable materials are sorted, manually removed and dropped by chute to storage bays beneath the station.
The BlueMAC MRF is helping Murray Browns to recycle C&W waste in the region of 18 tonnes/h and the bespoke materials plant has been designed with additional capacity to spare if volumes increase in the future.
