16.08.2021 Quadruple screw feeder handles biomass

Ajax Equipment, Bolton, UK, has supplied Enviropower, a leading biomass waste-to-energy provider, with a quadruple screw feeder measuring 11m in length for biomass waste processing.

The mild steel feeder will transport shredded pre-sorted biomass waste as part of the process to generate green electricity via steam driven turbines. As waste can be irregularly shaped, Ajax included a number of features to mitigate potential handling problems. The feeder includes generous clearance between each heavy-duty screw’s thick flights and the casing. While over the outlet section the feeder includes relief overload flap plates; this significantly reduces the potential for disruption should there be a blockage.  

In the event of maintenance, the feeder’s design allows individual screws to be removed while the remaining screws continue to operate. Commenting, Marc Linberry, operations director at Enviropower, said: “We have worked with Ajax previously and were confident they could provide a solution that met our needs, and the new system works very well.”

“The quadruple screw produced for Enviropower is one of the largest feeders manufactured by Ajax Equipment in its 50 year history,” said managing director Eddie McGee. “We have worked with Enviropower before on a twin screw feeder, horizontal collecting conveyor and two screw feeders for another part of their biomass waste to energy facility.”
