If I were to attempt to create a granule based extruder, I would try
and power it with air pressure, similar to how the frostruder works.
since you are controlling the pressure, temperature, plastic, and
aperature, you should be able to accurately predict the flowrate, or
at least get it to a repeatable state. As an added bonus, you'd get
nice start/stop control for free.

They also place the plastic under VERY high pressure, to push them
thru a filter. One of the VERY important aspects of using granular
plastic is to filter the molten plastic.
