BEUMER Group, Beckum, Germany, has developed a versatile screw weigh feeder suitable for handling a variety of cement industry raw materials and alternative fuels. To reduce the use of expensive primary fuels like coal and oil for energy-intensive cement production, operators are increasingly employing alternative fuels and raw materials. The company offers tailor-made systems for the entire material flow chain – from receiving and unloading the delivery vehicle to storing, sampling and conveying the materials.

Most alternative energy sources comprise fuels such as chopped waste tyres, plastic, paper, composite materials, textile and scrap wood mixes. They have differing bulk densities and can have an extremely high moisture content. These inhomogeneous bulk materials require considerable know-how in their handling. To be able to feed this material mixture, BEUMER, in cooperation with its customers, developed the screw weigh feeder, which can be equipped with an automatic calibration system. The highly precise system is suitable for the continuous, controlled and reliable transport of various bulk materials. Even explosive products can be safely conveyed as all components are available also in ATEX version.

The controlled feeding capacity is up to 30t/h. The system is dimensioned for bulk densities reaching between 0.08 and 0.8 tons per cubic metre. Depending on the local conditions, the weighing tolerance is between 1 and 2 per cent and enables very high consistency in controlled feeding. In addition, the completely closed screw weigh feeder is protected against dust and other environmental stress. www.beumer.com
