The SHRPROWEI - 1.0 is a machine developed by Weima in collaboration with Precious Plastic.

This machine uses the industrial approach that Weima uses for their shredding machines. A big strong rotor that spins to shred with pushers that press the plastic against it. Except for this machine the size is reduced and the hydraulic pusher is replaced by a manual one. This makes it easier to build, maintain while reducing manufacturing costs.

This innovative machine will allow individuals and communities worldwide to shred large amounts of plastic waste professionally, facilitated by its open-source design.

It supports the following plastic types: PP, HDPE, PS, PET, ABS, PLA (still more to be tested).

The Shredder PRO by Weima was designed for efficiency, safety, and easy maintenance????

- It allows for fast cleaning and sieve swapping, with disassembly and reassembly taking only up to 30 minutes .

- It features a single shaft rotor with interchangeable teeth, enabling easy blade maintenance and different configurations for various materials.

- A manual pusher efficiently handles objects of different sizes and shapes, ensuring smooth operation.

- The high hopper with a wide opening (450x220 mm) allows for large objects while incorporating a safety feature to prevent rotor access during operation.

- Overload protection prevents damage, ensuring long-term durability.

- With robust components, it can shred up to 100 kg/hour, making it ideal for medium-scale operations.

- Drawings are also ready for CE certification, ensuring compliance with European safety standards.
