Germany: Beumer Group has developed a screw weigh feeder with automatic calibration. The company says it is especially well suited to exact and controlled feeding of inhomogeneous bulk materials of densities between 0.08t/m3 and 0.80t/m3 and extremely high moisture content such as alternative fuels. Its capacity is 30t/hr and its weighing tolerance is between 1% and 2%. It is completely covered to prevent dust and other environmental stresses.
