Volumetric powder feeder consists of two or three key parts, depending on the material's flow characteristics. The feeder body, also known as the conditioning section, (optional) agitator, and auger screw.
Designing an efficient volumetric screw feeder requires careful consideration of various factors.
From screw feeders to vibratory feeders, bulk solids pumps, weigh belts, liquid feeders and flow meters, all feeders are offered in a variety of configurations, which can be combined to create an optimal solution for any application.

A screw feeder, in simplest terms, consists of a tube with a feed screw down the center. As raw materials are fed into the tube, the feed screw turns and moves the material along to a discharge unit located at the end of the tube. ... are industrial equipment used in transporting bulk quantities of granular solids (e.g., powder, grains ...
Flexible screw conveyors offer efficiency and versatility, conveying bulk materials ranging from large pellets to sub-micron powders - both free-flowing and non-free-flowing - with no separation of blended products.
Feeder design also impacts the degree of feed rate control. For example, twin-screw feeders can better regulate powder flow in comparison with single-screw configurations. This is because twin screws tend to dispense material in smaller pulses .
