Volumetric screw feeder..?

What is volumetric screw feeder?

What is a volumetric screw feeder?
A screw feeder has a rod with a thin spiral plate inside the pipe, and by turning it, the raw material and powder are going to be discharged.
Motor power is required to rotate it, and whole mechanism is that a control panel is necessary to operate the motor. Changing the subject,
what exactly is a volumetric screw feeder?

The screw feeder discharges the raw material by the volume of the raw material that entered the gap of the screw. Since the pitch of the screws is even, the amount of powder that gets between the screws is also the same.
Since the screw is rotated by a motor, the rotation speed is always constant (the rotation speed can be changed).
We call the method of continuously discharging the volume that enters the gap of the screw without weighing it as a volumetric screw feeder.

f you rotate at the same speed and for the same amount of time, the discharge amount will be roughly equal.
However, since it is not weighed, it goes without saying that the weighing type is better for accuracy,
but if you think discharge accuracy is not so important, volumetric screw feeder will work efficiently.
