A dosing pump is a small, positive displacement pump. It is designed to pump a very precise flow rate of a chemical or substance into either a water, steam or gas flow. A dosing pump will deliver this precise flow rate of chemical or other product by a number of different methods but it generally involves drawing a measured amount into a ...

For all Makes & Models of Coal Feeders * Improve plant heat rate * Account for fuel use Volumetric operation of a coal feeder has served the industry for many years. In a volumetric system the flow of material is controlled by the boiler demand system, but the actual amount fed is estimated and the accuracy can vary greatly.

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). The number regulation system in the coal feeder can be done in two ways based on the type, namely by weight fraction or coal volume fraction.

How Belt Feeders Work. A belt feeder consists of a hopper positioned directly over a belt conveyor. The belt conveyor "pulls" material out from under the hopper, while an adjustable vertical strike-off plate controls the height of material allowed to advance as the belt moves forward, or in other words, the material profile on the belt.

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.

As the name suggests, volumetric dosing systems only measure the volume of the ingredients (in cubic centimetres or meters, for example). Because the dosing device does not weigh the components, it must be calibrated to ensure that the correct mass is dosed over a set period.

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. In doing so direct measurement and control of discharge ...
