Bunting has added two new models to its range of Permanent Overband Magnets.
The company said that its new PMax and Easibelt models have been designed to meet specific requirements of reduced maintenance time and lighter weights.
The Overband Magnet is designed to be simple, with two pulleys mounted on a frame either side of a permanent magnetic block. The Overband Magnet is positioned above a conveyor, either over the head pulley, or more commonly across the belt. In operation, conveyed materials pass under the Overband and its strong magnetic field attracts, lifts and then automatically discards tramp ferrous metal such as rebar.
“The development of the PMax Overband Magnet meets the mobile plant industry’s move towards lighter and smaller designs – e.g. crushers and screens,” stated Bunting.
“The PMax is 15% lighter than standard the PCB model across the range and 12% shorter in length. These reductions result in a 14% higher magnetic force to weight ratio. The PMax operates at a maximum working height of 300mm (above the conveyor) on belts with widths between 600 and 1,500mm.
“The reduction in weight and size is achieved through adopting new manufacturing processes, including investing in new production plant. The new design is released in response to customer requests across Europe.”
The Easibelt model is for applications where maintenance opportunities are limited. It is designed to allow a fast belt change, reducing maintenance downtime by at least 50% compared with the changing of a belt on a standard Permanent Overband Magnet.
“The Easibelt is operates at a maximum suspension height of 300mm on belts between 600 and 1,500mm,” the company said. “This new design of Overband is specifically designed for 24-hour, 7-day operations where any production downtime can result in significant challenges. This new model is also ideal when an Overband Magnet is in a location with limited or difficult accessibility.”
Adrian Coleman, general manager of Bunting-Redditch in the UK, commented: “The development of two new designs of Overband Magnet meets the changing needs of our customers. Our PCB model has been an industry-standard for several decades and remains the optimum design for many applications. However, the PMax is specifically designed as a lower weight option for mobile plant, whilst the Easibelt offers significantly reduced maintenance time.”
The expanded range of Permanent Overband Magnets extends the range of Magnetic Separators and Eddy Current Separators that Bunting manufacturers for the recycling and quarrying sectors.
