Pelletizer vs Shredder
G-Pelletizer is a pelletizer or machine that processes materials into small, uniform, cylindrical shapes called "pellets" from filament extrusion.
University & R&D Labs: Perfect for material science research and testing new polymer formulations.
Small Batch Production: Ideal for creating color masterbatch samples or custom 3D printing filament pellets.
Compounding Tests: Used alongside micro-extruders to granulate strands immediately after cooling.
A shredder is a machine designed to cut, tear, or break large, bulky objects into smaller, irregular pieces. It uses high-torque rotating blades or shafts to destroy the original shape of the material to reduce its volume or prepare it for recycling.

Desktop Shredder
The difference between plastic shredder, crusher, and pelletizer.
A plastic pelletizer is a machine that is used to pelletize the plastic extrusion in the usual shape of filament into plastic pellets. A plastic pelletizer is usually used for compounding extrusion purposes to mix plastics or plastic with color masterbatch.
A plastic shredder is a machine that is used to recycle used plastic products like bottles and barrels. Shredder is known widely in the phrase paper shredder, you can imagine that the papers are shredded into slices strips, and uniform small pieces. A plastic shredder is just a machine for plastic products to be shredded.
A plastic crusher as usual is a machine for commercial recycling purposes, which is in larger volumes, large barrels, etc. It seems that Crusher has a stronger drive motor compared with Shredder. A crusher compresses first and then breaks the item, a car crusher is an example. A crusher is to break, a shredder is to break into pieces.
There are other words used to describe machines used for plastics, pulverizers, and grinders. Plastics can be found in two main shapes powder or pellet before it's used for products.
New update in 2023, the shredder and crusher are now the same as below RD-Shredder150
1. The shredder cannot be left unattended during operation to avoid accidents.
2. This equipment can be adjusted to forward and reverse. When switching, it needs to pause for 2 seconds. It cannot be switched quickly between forward and reverse to avoid damaging the motor.
3. After plugging in the power, press start, the forward machine starts working, and you can feed.
4. Press the red button to stop when not in use. To prevent accidental injury, do not put your hand into the hopper when using it.
5. It can tear thin metal products, such as thin iron sheets, roll-up banners, copper sheets, and metal sheets with a thickness greater than 1MM. Please note that the cutter may be damaged.
