#0183;#32;Feeders are auxiliary equipment that dispense a measured amount of an ingredienta resin, a colorant, or an additiveinto resin entering a processing machine. The term volumetric refers to one way that a feeder measures and dispenses an ingredient. The other way is called gravimetric. Lets briefly look at both:
The STOCK#174; gravimetric coal feeder weighs material on a length of belt between two fixed rollers (span) precisely located in the feeder body. A third roller, located midway in the span and supported at each end by precision load cells, supports half the weight on the span.
Gravimetric feeders represent a significant improvement over volumetric feeders. They utilize a computer and a load cell that continuously records the weight of the feeder and its contents. When the user inputs a given dispensing rate, the computer automatically calculates the rate and begins releasing the ingredient into the process.
Difference Between Gravimetric and Volumetric Feeder Jun 19, 2018 This is the main difference between gravimetric and volumetric feeder. Summary Gravimetric vs Volumetric Feede. Feeders are equipment that are important in handling solid bulks. They are useful to enter s solid into a processing system at a required rate.

Feeders are useful to handle bulk solids. There are two forms of feeders and we call them as gravimetric feeders and volumetric feeders.
A volumetric screw feeder feeds a certain material volume per unit time to a process. Such a feeder consists of a hopper, material discharge device, and controller. A gravimetric feeder adds a weigh system and new control scheme to what would otherwise remain a basic volumetric feeder.
nbsp 0183 32 The key difference between gravimetric and volumetric feeder is that we measure the rate of a gravimetric feeder in the unit of volume per unit time whereas we measure the rate of a volumetric feeder in the unit of weight per unit time Feeders are useful to handle bulk solids There are two forms of feeders and we call them as gravimetric feeders and volumetric feeders

Volumetric feeding falls short of capacity requirements when a material has a varying bulk density. Material that can vary widely in bulk density within a batch will struggle to meet dosing requirements with a Volumetric feeder. Gravimetric Feeding
Sep 10, 2019#183; The three differences between volumetric and gravimetric feeders 1) Open versus closed loop operation. Volumetric weigh belt feeders are openloop, setspeed devices, meaning they are dependent on a constant infeed of materials at a regular volume and density to work.
Gravimetric and Volumetric Coal Feed Systems for Boilers Coal properties constantly vary due to sizing differences and the adverse impact of moisture. Gravimetric feeders provide verification of the as used fuel to assist in the compliance with established standards.
the main difference between gravimetric and volumetric feeders is the high accuracy of gra vimetric feeders regarding the calorific (energy) trough put. the accuracy of volumetric feeders is mainly influenced by the variations in the following coal characteristics: density calorific value displacement volume (lump size) gravimetric feeders are
