2. Calculation of mechanical parts.
3. Design the mechanical parts on solidwork.
4. Printing and Assembling of Mechanical Parts.
5. Motor and Its control.
6. Testing of prototype.
The following are the technical details of Final deliverable from Plastic Shredder machine.
Shredding process:
Bottles is fed into cutting chamber and it shred plastic bottles into small flakes.
Result:
The maximum size of bottles is 1.5 litr (almost length 1.6 ft).After shred the size of flakes is almost 10 mm.
