Weigh Feeder

The electronic gravimetric Weigh Feeder incorporates state-of-the art technology for continuous bulk proportioning of solids. The material to be proportionally fed is passed over the belt; the flow rate (also cumulative value) of the material is measured and compared with set parameters of the PLC/ PID controller. The deviation is corrected by regulating the speed of the conveyor through variable speed AC drive (closed loop control system). Two high-precision load cells are used to measure the belt load and a rotary encoder used to measure speed of the conveyor. Precision-machined rollers are used to provide perfect belt run and high accuracy. Other features: rubber coated pulleys prevent belt slippage; gravity take ups ensure constant belt tension; scrapers are provided to prevent belt damage and tare changes; easy maintenance - belt change without aids from side; fully automatic zero/ span calibration; highly reliable PLC (with in built PID algorithm) and variable speed AC drive, high precision load cells with damping to obtain best results; empty belt correction factor to achieve best accuracy; and set points programmable from local panel or main panel. Optional feature: RS 485 interface can generate printout with SQC analysis.
