Weigh Loss Controller

Weigh Loss Scale Controller is used to correct the accuracy of volumetric feeders experiencing density fluctuations of the material passing through it. The hopper bin is placed on load cells. The scale senses the depleting weight. The controller compares the volumetric rate with the depleting rate and corrects the volumetric rate to the customer’s existing blending control.

Weigh Loss Scale-Controllers have proven themselves in applications requiring 10 tph Recycled Asphalt Shingles weighing 40 to 60 lbs/Cubic foot. Recycled Shingles vary in density, which affects the accuracy of any volumetric feeder.

Coal fuel generating plants can benefit as well. Coal varies in density and density is near proportional to BTU content.  It is easier to control the burner firing rate when the gravimetric density is known.  Accuracies are dependent on the application.

The added beauty to the system is that hopper weight is known.  Low bin level alarms are available. The system knows when the bin is bridging and can trigger bridge busting devices and/or sound alarms.
