Weigh Feeders

Active Weighing Solutions range of Weigh Feeders handle light/low flow rates up to heavy duty high flow rate feeders - indoors and outdoors

An Active Weighing Solutions Weigh Feeder is a slow speed short conveyor incorporating a single idler, full floating frame Belt Weigher design. Weigh Feeder models cater for bulk materials feed rates from 1kg to 5,000 tph and deliver weighing accuracy 0.5% and better.

Weigh Feeders are commonly used to control bulk material flow rate of into a process or to blend products on a continuous basis. Installed under a bin, an Active Weighing Solutions Weigh Feeder can be set to:

  • extract material at a specified rate, and
  • batch a pre-defined amount of material

Weigh Feeders provide continuous weighing with better accuracy than both Belt Weighers and Weigh Belt Conveyors because the cross sectional area does not change. Changes in bulk density are accommodated by the weigh controller which has the ability to increase and decrease the belt speed as required.

Multiple Linked Weigh Feeders

A number of Weigh Feeders used together can be linked to ensure that if any one Weigh Feeder runs out of product, all units would stop. Limit relays are available to provide an output signal to operators that there is a problem.
