The loss-in-weight feeders of the SF/BD serie are suitable for dosing flowing powders. The product enters into the hopper manually or through the throttle valve, the built-in mixer helps to feed the screw so as to avoid problems during the drop.
A weighing system with load cell measures the change in weight in real time. The required throughput is obtained by changing the speed of the screw driven by a motor with inverter. The machine is managed by a Siemens PLC which controls 1 to 8 dosing stations.
