For many plastic manufacturers, plastic lumps and purging waste are a real headache. These solid, irregular, and oversized chunks—generated during injection molding, extrusion purging, or machine clean-outs—are hard to manage and even harder to recycle without the right equipment.
Traditional granulators can’t handle these large, dense pieces efficiently. That’s where GEP ECOTECH’s specialized plastic lump shredders come in—turning difficult waste into valuable resources.

Tailored Shredding Solutions: Choose What Fits Your Needs
We offer two main types of shredders for handling plastic lumps, blocks, and purging waste. Each is designed for different materials, throughput, and output goals.
Dual-Shaft Shear Shredder
Heavy-duty performance for irregular and tough plastic lumps
- Twin shafts rotate at low speed and high torque, ideal for tearing through thick lumps and start-up purge blocks.
- Excellent for contaminated, mixed, or oversized materials that are too difficult for granulators.
- Simple, robust structure with low maintenance needs.
Typical applications
- Injection molding head blocks
- Start-up purge from extrusion lines
- Plastic chunks with metal or fiber reinforcement
- Processing before granulation or washing
Dual-Shaft Plastic Lumps Shredder | Plastic Scrap Shredder
The dual-shaft plastic lumps shredder is purpose-built for processing tough purging waste, injection molding lumps, and thick plastic blocks. Its high-torque, low-speed shear cutting system breaks...
Single-Shaft Shredder
Precision shredding for clean, homogenous plastic blocks
- Equipped with a hydraulic pusher and screen to control output size
- Delivers uniform chips that are easy to feed into pelletizing or compounding lines
- High efficiency for continuous recycling operations
Typical applications
- Clean purging plastic
- Uniform start-up waste
- High-quality recovery lines for pellet production

Processing Injection Lumps in Malaysia
One of our clients in Southeast Asia operates a high-throughput recycling line that handles 1.2 tons per hour of PP injection molding lumps and purging blocks. They chose our GD6 dual-shaft shredder for its strong shearing ability, stable operation, and low energy consumption. The shredded material is cleaned and pelletized for reuse in non-critical molded parts.
