When looking for ways in which to improve the efficiency of their current process, and reduce wear and tear on their existing plant and shredder, Weir Waste turned to machinery distributor Blue Southern. Who, with the help of sister company BlueMAC Manufacturing, designed, manufactured and installed an innovative, tailor-made BlueMAC recycling plant with health and safety at the forefront of the build. The plant currently processes around 25-30 tonnes per hour; meaning an initial rate of between 180-220 tonnes per day. As well as significantly contributing towards the company’s waste recycling capabilities, the plant has also helped to enhance their reputation for reliability -as shredder machinery down time has notably decreased since installation.
The plant also includes a pause peddle which was integrated to allow pickers to momentarily stop the picking conveyor in order to break down balls of material. This feature was specifically integrated to reduce the number of balls of material being swept, by pickers, into single bins and so improving final material purity. When pressed, the pedal also immediately alerts the loader operator, via a traffic light system, that the plant is in a paused state.
In order to comply with Weir Waste’s high standard of health and safety, BlueMAC also incorporated the double safety mechanism of a castel locking system when designing the plant. This locking system includes a main locking key and a further 6 access keys for risk areas of the plant within a central locking ‘bank’. Only when the main key is in the off position and the plant is not operational can a risk area key be released for access to that particular area. This means that if a key to a risk area is removed to gain access for maintenance, the system ensures the safety of the maintenance operative as the plant will not become operational. It also requires for the master key to be removed from the power isolation switch and integrated into the key bank before any entry keys can be removed. Any risk areas must also be fully secured before the key to that area can be released, by the locking mechanism, for placement back into the main bank.
