DYSSH Series Heavy Single Shaft Shredder

Designed for heavy-duty recycling applications, the DYSSH Series (DYSSH-800 / DYSSH-1400) delivers exceptional shredding performance with low-speed, high-torque cutting action. Whether processing plastic lumps, wood waste, electronic scrap, or industrial rejects, these single-shaft shredders help you achieve consistent particle size and reliable uptime.

Application

Thanks to the Φ400 mm rotor diameter and modular blade configuration, the DYSSH Series is widely used for:

Plastic Recycling – HDPE/LDPE drums, PP woven bags, ABS lumps, engineering plastic waste.
*Case: A recycling plant in Mexico uses the DYSSH-800 to process 700 kg/h of discarded blow-molded HDPE containers, reducing volume by 70% before pelletizing.*

Wood & Biomass – Plywood scrap, pallets, wood blocks (moisture content <15%).
*Case: A wood panel factory in Vietnam uses the DYSSH-1400 to shred pallet offcuts into 30–50 mm wood chips, feeding directly into a biomass boiler. Average output: 1,300 kg/h.*

E-scrap & Cables – Aluminum/copper radiators, monitor plastic housings, small e-waste.
*Case: An e-waste recycler in India uses the DYSSH-800 to pre-shred old monitor housings (ABS/PC), liberating metals for downstream separation.*

Rubber & Fiber – Tire sidewalls (after bead removal), rubber seals, fiber-reinforced conveyor belts.

Advantages

Feature	DYSSH-800	DYSSH-1400	Advantage
Rotor diameter	Φ400 mm	Φ400 mm	Uniform torque distribution, handles dense materials
Drive power	90 kW	160 kW	High crushing force for thick-walled or solid materials
Rotor blades	40 + 38	60 + 56	Fine and powerful shredding; staggered layout reduces dead zones
Stationary blades	3 + 3	5 + 5	Double-shear cutting effect, self-cleaning design
Output range	600–800 kg/h	1,200–1,500 kg/h	Scalable to medium/large recycling lines

What truly makes DYSSH stand out:
Low-speed, high-torque drive – Prevents jamming and overheating even when processing materials containing metal contaminants.
External bearing housings – Keep bearings away from dust and fine particles, extending service life by 40% compared to conventional designs.
Quick blade change – Rotor blades are bolted onto replaceable blade holders; no need to disassemble the entire rotor (full changeover downtime < 2 hours).
Hydraulic pusher with adjustable pressure – Automatic feed control reduces bridging of hollow materials (e.g., drums, pipes).

Process

Every DYSSH machine undergoes a 6-stage quality control protocol before shipment:

① Raw material inspection
Rotor steel: 42CrMo forging, hardness HB 240–280.
Blades: Cr12MoV or D2 tool steel, HRC 56–60, impact toughness ≥30 J/cm².

② Welding and structural inspection
100% magnetic particle inspection (MPI) of rotor body welds.
Vibration test: ≤0.05 mm/s under no-load conditions.

③ Assembly precision
Rotor dynamic balance accuracy: Grade G6.3.
Stationary blade gap adjustment: 0.8–1.5 mm, verified with feeler gauge at 12 points.

④ No-load run test (4 hours)
Monitor bearing temperature rise (≤40°C), noise level (≤85 dBA at 1 meter).

⑤ Load test (simulated production)
DYSSH-800 – Shred 500 kg of 10 mm thick HDPE plate; recorded output: 720 kg/h, motor current stable at 88% of rated value.
DYSSH-1400 – Shred mixed waste (plastic+wood+aluminum profiles) at 1,350 kg/h, power fluctuation within ±5%.

⑥ Final inspection
CE safety compliance check (interlocked guards, emergency stop, reverse function).
Each machine comes with a 30-item test report signed by the QC engineer.

Model	Rotor Dia.	Drive Power	Rotor Blade	Fixed Blade	Output(kg/h)
DYSSH-800	Φ400	90	40+38	3+3	600-800
DYSSH-1400	Φ400	160	60+56	5+5	1200-1500

Q1: Can the DYSSH-800 shred steel drums (e.g., 200L closed-head drums)?
A: Yes, but we recommend crushing or de-gassing them first. The Φ400 rotor with 40+38 blades can handle drum wall thickness up to 1.5 mm. However, if you process drums daily, choose the DYSSH-1400 (25% higher pushing force). Be sure to remove non-metallic parts such as plastic caps or rubber gaskets.

Q2: How often should I change the blades?
A: Blade life depends on the abrasiveness of the material:
Clean plastics (PP/PE): 400–600 operating hours.
Wood with nails: 150–250 hours (one blade flip).
E-waste (ABS): 300–400 hours.
Both models support 4-edge usage (rotate blade 90°). When all edges are worn, replace the entire set of blades. Typical cost per edge for DYSSH-800: approx. 1.2–1.2–1.8 per blade.

Q3: Does the machine have overload protection?
A: Yes. The PLC monitors motor current in real time. If a jam occurs (e.g., a metal block), the shredder automatically:
Stops the pusher
Reverses the rotor for 3 seconds
Re-attempts forward rotation (up to 3 times)
If unsuccessful, an alarm is triggered. This protects the gearbox and blades from sudden damage.

Q4: What is the typical output particle size?
A: Depends on the installed screen mesh size (10–80 mm optional). For standard recycling:
20 mm screen → 85% of output <25 mm (suitable for granulator feed).
40 mm screen → for washing lines or air classification.
*Note: With the same screen, the DYSSH-1400 (with 60+56 blades) produces slightly finer particles than the DYSSH-800.*

Q5: Can I shred bundled wires or cables?
A: Yes, but copper/aluminum conductor diameter must be <8 mm. The stationary blades (3+3 or 5+5) produce a shearing effect that cuts through insulation. However, do not feed armored steel tape cables – this will damage the rotor blades. A magnetic separator is recommended before the shredder.

Q6: What are the power requirements for the DYSSH-1400?
A: Three-phase, 380–415V / 50Hz or 460V / 60Hz. Starting current: 650A (star-delta starter included). For a wiring distance of 50 meters, you need a 200A main circuit breaker and 95 mm² copper cable.
