Plastic Lumps Crusher Machine

Product Overview

Plastic Lumps Crusher Machine Manufacturer

Heavy plastic waste—such as purging blocks, thick-walled extrusions, start-up lumps, and massive injection moulding purgings—presents one of the toughest recycling challenges in plastic manufacturing. Standard granulators struggle or jam when processing high-density, thick plastic masses. The Shred Maxx Plastic Lumps Crusher Machine is specifically engineered to handle high-impact, thick-walled plastic waste that standard scrap grinders cannot break down.

When plastic extruders or injection molding units undergo material changes, shutdowns, or process start-ups, the resulting solidified purge lumps represent high-value resin locked in an unusable form. Shred Maxx Lumps Crushers utilize ultra-high torque drive systems, heavy-duty solid rotors, and reinforced cutting chambers to fracture and granulate dense plastic masses into uniform flakes. By transforming unmanageable purge blocks back into reusable regrind, manufacturers eliminate costly disposal fees and significantly reduce raw material costs.

Key Advantages of Plastic Lumps Crusher Machine

1. Handles Extremely Dense Plastic Waste

High-torque, low-speed rotors bite through dense blocks (HDPE, PP, ABS, PC, Nylon, PEEK) without stalling or flywheel slippage.

2. Significant Cost Recovery

Converts purge lumps and start-up waste into reusable, high-grade resin instead of low-value scrap or landfill costs.

3. Lower Power Consumption per Tonne

Low-RPM, high-torque shearing saves up to 30% power per kg compared to high-speed granulators.

4. Continuous Non-Stop Operation

Heavy-duty flywheels and auto-reverse rotor system clear jams instantly, keeping production running without manual intervention.

Working Principle of Plastic Lumps Crusher

1. Feeding

Solid plastic lumps, purge blocks, or pipe ends are loaded via conveyor, forklift, or manual intake.

2. Compression & Engagement

Hydraulic rams (where equipped) push the lump toward the rotor, keeping it stable during cutting.

3. High-Torque Shear Reduction

Staggered rotary knives take bite-sized shear cuts, using high gear-drive torque to slice through the dense mass.

4. Screening & Discharge

Reduced chips pass through the screen mesh and exit — ready for direct re-granulation or further fine grinding.

FAQs – Plastic Lumps Crusher Machine

It handles dense thermoplastics like HDPE, PP, ABS, PC, Nylon, and PEEK, including purge blocks, pipe ends, and start-up waste.

No. The reinforced hopper and high-torque rotor accept solid lumps directly, without manual size reduction.

No. Auto-reverse rotor function and overload protection clear blockages automatically, avoiding motor damage.

Yes. Interchangeable screen mesh sizes let you set the final flake size for your downstream process.

Its low-RPM, high-torque design saves up to 30% power per kg compared to standard high-speed granulators.

Hardened tool-steel blades offer long life, and the easy-access chamber design allows quick replacement when needed.
