FEEDING - WEIGHING BELT WEIGH FEEDER DLN DEFINITION AND PRINCIPLE The DLN belt weigh feeder extracts a product from a storage hopper through the constant cross-section and according to a fixed reference flow-rate (set point), adjusts the extracted volume by varying the belt speed in such a way as to keep a constant weighed flow-rate. The weight of the material on the belt length called ‘weighing length’ is measured by a strain gauge load cells weighing system. The belt speed is measured by an incremental encoder and adjusted by a variable speed gear motor. The DLN belt weigh feeder can also be used as a continuous weigher for throughput and consumption measurement or as a charge pre-selection (batch) feeder. COMPOSITION AND CHARACTERISTICS The DLN belt weigh feeder consists of three main parts: 1 belt conveyor mounted on a support frame 1 weighing device and a belt speed transducer 1 electrical and electronic control and regulating system Sealed protective case and discharge hood with de-dusting connection flange 2 Infeed hopper with manual adjustable 1 slide gate Geared motor directly connected to the drive shaft. Frequency controled 3 3ph AC motor IP 55, Classe F, 380/400/460 550 or 660V 50 or 60 Hz Digital speed detector by incremental 7 encoder Automatic belt self centering device. 6 Two belt deviation sensors 5 Automatic belt tenssionning by contre weight Weighing system including the weighing idler, two strain gauge load cells (IP 68, 3000 divisions OIML) and a digital signal processing unit. ADVANTAGES Simple and robust machine, easily adjustable to various products characteristics Limited dimensions for flow-rates of up to 1000 metric tons/hour. Easy extraction and feeding of various difficult products (arching and clogging) Feeding is 100% gravimetric, Very extensive range of flow-rates from 1 to 30 Weighing and feeding accuracy:+/- 0,5 % At the center of your syste
