Accessories & Supporting Components

Shredder Chamber & Cutting Box

The shredder chamber is the core working unit of every double-shaft shredder. Fabricated from thick welded steel plate, it houses the cutter shafts, spacers and fixed counter knives. Removable side panels simplify cutter replacement and internal cleaning. Chamber geometry, cutter thickness and clearances directly define the final particle size and output consistency.

Drive Motor

Shredder drive motors must withstand shock loads, frequent forward-reverse rotation and sustained operation under material jams. We specify cast-iron housing, heat-resistant windings and overload protection. Standard high-efficiency and VFD-compatible variable-frequency models are available to match the control system and power supply.

Hard-Tooth Reducer / Gearbox

Carburized and quenched hard-tooth reducers deliver the low-speed, high-torque shear required for shredding. The gearbox absorbs instantaneous torque shocks from contaminated material and supports reliable forward-reverse cycling. Available in K-series and ZQ-series housings sized to the motor and cutting load.

Frequently Asked Questions

Q Is the 250 model more powerful than the 150 model?

Not necessarily. The published 250 configuration lists a 2.2 kW motor, while the 150 lists 3 kW. Compare the complete drive and cutting system, rather than treating model numbers as a power ranking.

Q Can the same configuration process rigid plastic and plastic film?

Do not assume equal performance. Rigid pieces and flexible film behave differently during feeding and cutting. Include both materials in trials, checking reliable engagement, wrapping, interruptions and output suitability before confirming the cutter configuration.

Q How much material preparation is needed before feeding?

Assess oversized pieces, long flexible items and foreign objects before selecting a feeding method. Agree on acceptable feed conditions with the supplier. Preparation requirements should be included when calculating labor, cycle time and operating cost.

Q What should a meaningful throughput test include?

Use representative material and a defined batch weight. Record elapsed time, feeding method, stoppages and output condition. Include normal operating interruptions in the agreed calculation so the result reflects your production process.
