The Coperion K-Tron Smart Weigh Belt Feeder (SWB) is used for continuous controlled gravimetric feeding of free-flowing or friable bulk materials. The feeder can be used for gravimetric batch feeding or for continuous metering of bulk material flow. The SWB features a primary weigh bridge and offers an optional secondary weigh bridge that provides continuous online auto tare, reducing maintenance, frequency of calibration, and improving long term stability. Material weight on the primary weigh deck and belt tare weight on the secondary weigh deck are determined by Coperion K-Tron’s patented SFT III weighing technology with vibration and temperature immunity, zero deflection and resolution of 1:4,000,000 in 80ms. The SWB is available in 300mm, 600mm, 650mm, 800mm and 1000mm belt widths. The SWB-300 and SWB-600 are supplied as open or closed frame.
