Gravimetric Feeder

We offer a wide range of Gravimetric Feeder to our customers. The bulk material or liquid is discharged from a hopper by weighing the material being fed and regulating the speed of the feeding device. The weighing system with control compensates for non-uniform material flow characteristics and variations in bulk density, and therefore provides for a high degree of feeding accuracy. Applications: Monitored feeding.Material control. Set point input manually or by host computer or in master/slave operation.

K-Tron generally employs following types of gravimetric feeding: Loss-in-weight feeding Weigh belt feeding Flow metering Loss-in-weight feeding principle: A feeding device with a hopper containing the material to be fed is placed upon a platform scale or suspension scale weighing system. The weight of the feeding device and hopper is electronically tared. The bulk material or liquid is discharged from the hopper by the feeding device and the resultant weight loss is determined by the weighing and control system. This actual weight loss is compared to a desired weight loss per unit of time based upon a desired continuous feed rate setpoint. Any difference between the actual and desired weight loss per unit of time results in a correction to the speed of the feeding device. When the hopper content reaches a predetermined minimum weight level
