Gravimetric Belt Feeders For The Agricultural Industry

Brabender Technology GmbH & Co. KG manufacture a wide range of Belt Feeders, suitable for use in the food, plastic and chemical industry sectors. The belts are available in several sizes, starting from a 150mm belt width, the belt feeders can operate between 10kg/hr and 50 tonnes/hr of product depending on the size of the machine used. The Brabender belt feeders can be used as continuous feeders, batch feeders or as a measuring belt feeder for continuous throughput measurement. Due to an adjustable gate after the inlet to the belt, each belt feeder has a huge turndown ratio of up to 100:1. The measuring of the product is achieved just after the gate using a loadcell, a torsion bar and weighing bridge that the product runs over on the belt. The product is weighed as it travels over the loadcell and the Brabender Congrav controller then calculates what speed the motor should run at to maintain a specific feed rate. In a similar way, the bet can be ran at a fixed speed and the loadcell is then used to indicate a throughput.
