Basics
- This page aims to organise and conduct research on the Pelletizer.
Main Types of Pelletizers
Screw Based
- Similar to a filament extruder, but with a rotating "cutter" on one end
- Changing the speed of the cutter wheel changes the pellet length
- Due to being able to seal the tube, and still run the screw, can higher densities be reached due to the increased pressure? Needs More Research
- These have less throughput, so may not be the best option for large scale use, but better for home use perhaps
Die Based
- Typically use a roller, and a sort of mesh/honecomb with the holes being the shape and dimention of the pellets
- Powder is added to the top and is pushed through the mesh making pellets
- VERY high throughput
- Often unpressed powder mixed in output, so more post processing is needed such as a shaker grate
- May have less pressure and thus lower density?
- Also can pellet length be varied (perhaps swapping screen for one with longer "tubes"
- OR some sort of dual mesh device with rotating wheels with holes, so it can be "sealed" like the screw extruder?
