• WEIGH BELT FEEDER (mini weigh feeder)1The MINI weigh belt feeder extracts a product from a storage hopper through the constant cross-section and according with a fixed reference flow-rate (set point), adjusts the extracted volume by varying the belt speed to keep a constant weighted 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 MINI weigh belt feeder can also be used as a continuous weigher for trough-put and consumption measurement or as a charge preselection (batche) feeder. COMPOSITION AND CHARACTERISTICS _______ The MINI weigh belt feeder consist of three main parts: • A belt conveyor mounted in a closed • A weighing device and a belt speed trans- • An electrical and electronic control case ducer and regulating system Digital processing unit Drive unit with AC gear motor Convex drive and return drums facilitating the selfcentering of the belt, Optional rubber coated drums • Feeding and handling of difficult and fragile products • 100% gravimetric feeding • Very extensive range of flow-rates, from 1 to 30 • High weighing and feeding accuracy : +/- 0.5% Machine completely closed and very clean when de-dusted • Fast and easy lateral belt remplacement • Low volume of installation for a throughput up to 60 m3 per hour

• The MINI weigh belt feeder is used for the continuous weighing and feeding of powders, granules, flakes and fibres. • Food industry : Cereals, biscuits, confectionery, chocolate, pasta, canned food, pet food.. • Chemical industry : Detergents, pesticides, fertiliser, detergent products • Building materials : Gypsum, plaster, starch, additive (Mn02, CaC03) • Plastics industry : Plastics, compounds, fibres • Aluminium : Feeding of petrol coke, burnt or hard scraps The Mini weigh belt feeder is controlled by a Sautelma's universal microprocessor controlled measuring system called MINISMART....
