Single Shaft Shredder for Plastic Recycling
Our single shaft shredder delivers flexible size reduction with precise control for uniform output. The robust rotor design and adjustable screen ensure consistent particle size, ideal for washing lines, extrusion and pelletizing systems.
Product Overview
Applications include rigid plastics (HDPE, PP, PVC), film scrap, purgings and in-plant recycling. Low-speed, high-torque operation reduces wear and noise while maintaining throughput. The machine is often used as the first stage before washing or granulating.
Gangsu single shaft shredders are designed for 24/7 operation with easy maintenance, reversible blades and durable construction. Options include hopper design, conveyor integration and custom screen sizes.

FAQ
What is the difference between single shaft and double shaft shredders?
Single shaft shredders use one rotating rotor and are ideal for precise output control and uniform particle size. Double shaft shredders use two counter-rotating shafts for higher throughput on bulky items. Choose single shaft for washing lines and extrusion; double shaft for primary reduction of large rigid plastics.
What materials can the single shaft shredder process?
Our single shaft shredder handles rigid plastics (HDPE, PP, PVC), film scrap, purgings, PET bottles and mixed plastic waste. Screen size and blade configuration can be adjusted for your material and desired output.
How do I maintain the shredder blades?
Blades are reversible for extended life. Regular inspection and timely reversal or replacement minimize downtime. We provide spare parts and maintenance guidance for your specific model.
