Volumetric Feeders | MERRICK Industries, Inc.
Volumetric feeders can provide reliable feedrates with accuracies to ± 1 % by volume, or ± 3% by weight. Volumetric feeders meter a consistent volume of material, such as a screw pocket, by the speed or revolution rate of the discharge device. This releases a steady quantity of material over time, which provides an economical way to meter ...

What is the difference between volumetric and gravimetric?
· Coal Feeder is a device that regulates the amount of coal to be supplied into the Coal Mill. The amount of coal is regulated according to the needs in the boiler combustion chamber (furnace). What is a gravimetric feeder? A volumetric screw feeder feeds a certain material volume per unit time to a process. Such a feeder consists of a hopper, ...
The benefits of going gravimetric
· But gravimetric feeders also have an impact on the feed out of the coal bunkers, which in turn has a substantial effect on the efficient performance of the boiler. A volumetric feeder arrangement, which is usually in the form of a drag chain feeder, assumes a given volume of coal is being extracted.
