Volumetric Feeding Vs. Gravimetric Feeding

Here volumetric feeding Vs. gravimetric feeding.Volumetric feeding rotating screw pushing material toward discharge, a rotary feeder dumping its pockets, or a vibratory tray jostling the material forward.While the gravimetric feeding is a basic volumetric feeder. In doing so direct measurement and control of discharge rate becomes possible. 

 

 

 Volumetric Feeding Concept :

 

1.Volumetric Feeder rate must be inferred from feeder speed

2.Sensitive to material build-up or other factors affecting calibration

3.No direct measurement of material throughput

4.Regular recalibration required

 

 Gravimetric Feeding concept:

 

1.Direct measurement and control of feed rate

2.Automatically compensates for material density variations

3.Direct measurement of material rate and throughput

4.High performance accuracy potential
