Collard invests in material recovery

By Lindsay Gale08 April 2014

R Collard Ltd has taken delivery of a state-of-the-art material recovery facility designed and built by BlueMAC and supplied to Collard by Blue Machinery London, with the equipment having been installed in the company’s recently opened recycling facility in Eversley, Hampshire – one of four such sites operated by Collard. Designed by BlueMAC specifically to meet Collard’s requirements, the MRF will initially be predominantly processing construction and demolition waste although it will be able to handle other types of waste should that be required in the future.

The new MRF is part of a planned expansion of the company’s recycling activities and is a necessary response to the growing volume of waste materials available for recycling from the company’s increased demolition work and expanding skip hire activities.

The system consists of a variable speed belt that feeds a 2510 trommel that removes fines at 50 mm (2 inch) that are transported by a transfer conveyor, passing under a overband magnet to remove ferrous metals. The material is then passed into the fines processing system by a conveyor fitted with a magnetic head roller to remove smaller ferrous items that are collected via a chute into a skip.

The remaining material passes over a flip-flow screen for processing of fines from -10 mm (0.3 inch). The 10 to 50 mm material is then segregated through a GK air classifier for heavy and light separation. The +50 mm material passes an air separator after the trommel before entering the picking station, purpose designed as a six bay, double sided configuration with six additional drop boxes for high value materials. A 1.5 m (4.9 ft) wide variable speed conveyor belt provides optimum material spread for maximum recovery. An overband magnet after the station cleans the remaining material dropping ferrous metals into the same collection area as the fines transfer belt.
