The K-Tron Smart weigh belt feeder offers continuous online auto tare compensation by using 2 digital weigh modules. The first module measures the actual belt weight before receiving material, including the weight of material sticking to the belt. The second determines the gross weight after receiving material onto the belt. The feeder compensates for the difference. The feeder is available in 300 and 600mm belt widths. The SWB-300 model offers feed rates of 44 to 44,000 lb./hr. or 0.4 to 1,400 ft.3/hr.; the SWB-600 unit is designed for feed rates of 88 to 88,000 lb./hr. or 0.7 to 2,800 ft.3/hr.
