==Overview==
=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


==Research==
==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?

Hello,
I present to you my French site.
I am mainly looking for how to build machines that can exploit the
biomass of the high Pyrenean valleys, such as wood chippers and pellet
presses.

*Also a powder hopper, a stepper motor, and the cutting disk seem like the only additions needed

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?
