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.
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.
A film shredder is a size-reduction machine built for thin, flexible plastics — stretch film, agricultural film, shrink wrap, woven bags and plastic bags — producing consistent flakes ready for washing and pelletizing. Standard crushers are intended for rigid plastics; film needs the shear cutting of a single shaft rotor.
A massive, specially shaped rotor runs at low speed (around 74 RPM) with high torque. A hydraulic pusher ram presses condensed film bales into the cutting chamber, where rotor knives shear against stationary counter knives — cutting rather than ripping the material.
Output size is controlled by an adjustable, interchangeable screen mesh (normally 40–100 mm). Material not passing the screen re-enters the cutting chamber. In practice, wet or sand-loaded film bales are often run first through an 80 mm screen, then re-shredded at 40 mm for finer washing feed.
One profiled rotor with self-acting knives cuts against stationary counter knives at low speed (60–85 RPM) and high torque.
Two counter-rotating shafts with interlocking blades run at very low speed (15–30 RPM) with extremely high torque.
Angled blade engagement peels through film and thin composites for higher throughput and lower noise.
Each concave ground square knife rotates four times before sharpening; externally adjustable in minutes.
A swing-type pusher presses material against the rotor at precise pressure and prevents film wrap-around.
Amp-meter control reacts to motor load and reverses the rotor to eject metal, stones and unshreddable objects.
Hydraulic screen cradle swaps screen types in under 15 minutes for fast changeover between material streams.
Rundown safety device, hinged two-piece guard and CE / UL / CSA compliant protection for safe operation.

A shredder is the first step of the recycling process. When integrated with washing, drying and pelletizing, the shredder must be sized to match line capacity — a correctly matched screen aperture and throughput prevent bottlenecks downstream.
Every shredder is delivered to the strictest international safety standards, keeping operators protected and simplifying market approval worldwide.
A film shredder uses a low-speed, high-torque rotor with a hydraulic ram to cut flexible films into uniform flakes. Granulators run at high speed and work best on rigid plastics — film tends to wrap around high-speed rotors, causing jams. The single shaft design with a hydraulic pusher avoids this.
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 film, washing lines and extrusion; double shaft for primary reduction of large rigid plastics.
The shredder handles PE (LDPE, LLDPE, HDPE), PP (woven and non-woven), PVC film, agricultural film, stretch wrap, plastic bags, non-woven fabrics and rigid scrap. Screen size and blade configuration can be adjusted for your material and desired output.
For direct pelletizing of clean film use a 40 mm screen for fine flakes. For washing lines, 60 mm balances throughput with surface area for contaminant removal. For coarse pre-shredding of baled material, use 80–100 mm screens for maximum throughput.
Each knife has four cutting edges, so you rotate three times before resharpening. On clean PE/PP film a full set lasts 800–1,200 operating hours; abrasive materials reduce this to 400–600 hours.
Yes. The shredder is the first stage before washing, granulating or pelletizing. We can size the shredder, motor and screen to match your line capacity and provide integration support.
The overload protection system monitors motor amperage and reverses the rotor to eject metal, stones or other unshreddable objects. For ongoing abrasive contamination, wear-resistant rotor components and hard facing are available.
