The twin-shaft industrial shredder is the dual-shaft shredder for solid industrial waste — plastics, rubber, wood, paper, composites, rejects — that requires size reduction prior to recycling or disposal.
The twin-shaft industrial shredder has 2×30kW/380V (Luan Jintai), K127×2 gearboxes, a Schneider Electric PLC, 21rpm/25000Nm, 27 9CrSi blades Ø350×30mm, a 1500×1000×600mm hopper and weighs 5200kg.
The twin-shaft industrial shredder operates at low speed (21rpm) and high torque (25000Nm), which allows it to process hard and tough materials without generating excessive heat or causing thermal degradation of the processed material — an essential characteristic for plastic and rubber waste that must remain recyclable after shredding. Transport, installation and commissioning included. 60-month warranty. Technical specifications — twin-shaft industrial shredder

• 25000Nm torque at 21rpm — low-speed shredding without heat generation — the twin-shaft industrial shredder operates with sufficient shearing force for hard materials without raising the temperature in the shredding chamber. This characteristic of the twin-shaft industrial shredder is critical for plastic and rubber waste, where excessive heating degrades the polymer and reduces recycling value, and also for confidential documents, where controlled temperature prevents paper ignition.
• 27 blades in 9CrSi alloy steel Ø350×30mm — maximum durability on abrasive materials — the twin-shaft industrial shredder has 27 cutting blades made of 9CrSi alloy steel (with chromium and silicon), which offer hardness and wear resistance significantly superior to ordinary carbon steel, essential for shredding abrasive materials such as used tyres with steel wire, auto parts with metal inserts, fibreglass-filled plastics and composite waste. The extended service life of the twin-shaft industrial shredder's blades reduces the replacement frequency and the operating cost per tonne of material processed.
• 1500×1000×600mm feed hopper — processing large pieces without prior preparation — the twin-shaft industrial shredder has a 1500×1000×600mm feed hopper that allows large pieces and chunks to be fed directly into the shredder, without manual pre-cutting or sawing. The generous dimensions of the twin-shaft industrial shredder's feed hopper significantly reduce the cost and time of material preparation and allow direct processing of whole pallets, large plastic parts from household appliances and large construction elements.
• 2×30kW with Luan Jintai motors and K127 gearboxes — industrial power for continuous production — the twin-shaft industrial shredder has two 30kW motors with Luan Jintai motors and K127 gearboxes that provide the power required for continuous production across multiple shifts, without thermal overload or accelerated wear when processing hard materials. The twin-shaft industrial shredder's architecture, with two independent shafts, also ensures continuity of production in the event of maintenance work on a single shaft, minimising planned downtime.
• Schneider Electric PLC — precise control, automatic protection and diagnostics — the twin-shaft industrial shredder has a Schneider Electric PLC control system that manages motor start and stop, detects overload and jams and triggers the automatic rotation-reversal sequence to release jammed material. The automatic diagnostics of the twin-shaft industrial shredder's PLC reduce the technician's intervention time for common faults and protect the blades and gears against damage from prolonged jamming. 60-month UZINEX warranty, national technical support within 24–48 hours.
Applications — twin-shaft industrial shredder
Plastic recycling companies use the twin-shaft industrial shredder as the first stage of the processing flow, reducing large pieces of rejected plastic and oversized packaging to granules of 20–80mm that can be fed directly into the extruder or pelletiser. The 1500×1000×600mm feed hopper capacity of the twin-shaft industrial shredder eliminates the need for an additional primary size-reduction stage.
Authorised operators treating end-of-life vehicles (ELV) and waste electrical and electronic equipment (WEEE) use the twin-shaft industrial shredder to shred plastic, rubber and composite parts after the removal of valuable components, reducing the waste volume for transport and preparing the material for subsequent separation by density or magnetic separators. Frequently asked questions about the twin-shaft industrial shredder
What particle size does the twin-shaft industrial shredder produce?
The output particle size of the twin-shaft industrial shredder depends on the spacing between the blades and can be adjusted by selecting the blade configuration when ordering the equipment. At quotation stage, UZINEX confirms the particle size obtained for the specific material in the customer's production flow and configures the equipment accordingly.
