The following tasks should be sufficient in order to assemble the shredder. If everybody is fine with github, we can also move this task list into a project on github. Please contact [[User:NitramLegov|Martin]] if you want this to be done.

The shredder is the first machine we are building for the Precious Plastic project as all the other machines require small, somewhat uniform pieces of plastic as their raw material.

Materials

Armin got the laser cut parts and two flange bearings; they are in a box in the metal workshop.

Lukas contributed a piece of 27 mm (Schlüsselweite) hexagonal steel.

Components:

  • 3 kW, approx. 1500 rpm Drehstrom-Asynchron-Motor
  • gearbox: 20:1
  • electronic components:
    • emergency stop: TBD (similar to the one at the CNC router)
    • 1xMotorschutzschalter 6,3-10A Gekauftes Modell:
    • 2xLeißtungsschutzschalter mit Hilfskontakten Gekauftes Modell: DIL EM 01 G mit 22 DIL E
    • 2xLeuchttaster für rechts- linkslauf
    • Stopp Taster
    • 3Phasen Hauptschalter

Missing:



We have a small selection of perforated metal plate (Lochblech) that could be adapted (cut and perhaps re-drilled) to be the "sieves" determining the particle size that comes out of the shredder.

Other materials include threaded rods and other metal parts that we should already have at the Space.
