WEIGHT FEEDER

Designed to ensure a precise and continuous feeding process at a desired flow rate and and accurate batching of various raw materials according to set recipes, Leader WF weight feeders find application in such industries as concrete, metal, chemical, grain and food.

FIXUM CQ weighing unit, used with feeding belts, collects the weight data from the load cell and the speed data from the encoder mounted on the tension idler. Based on the PID (proportional, integral, derivative) control principle, the motor speed is adjusted to such a value that the set flow rate is secured. The instant flow rate is then transmitted to the central control system either digitally or analogue. Thanks to the motor speed control a raw material flow at a set rate can be achieved.

The operating status, target flow rates, instant flow rates, total amounts of material, error and warning messages can be displayed or set through the indicator or if desired, through a PLC acting as the central processing unit with a graphic-display operating panel connected to it.
