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 When should I consider the two-motor configuration?

Consider it when a technical assessment identifies a drive requirement that the proposed single-motor arrangement cannot meet. Confirm motor ratings, drive layout and control behavior. Two motors do not automatically mean twice the throughput.

Q Can the 400 model shred solid metal blocks?

The product page excludes extra-large, thick solid metal blocks. Do not interpret general industrial-waste suitability as approval for every metal item. Provide alloy, section thickness, dimensions and photographs before requesting an application assessment.

Q Does a larger chamber eliminate the need to pre-cut material?

No. Chamber size is only one constraint. Long, bulky or thick-walled items may still feed poorly or exceed the cutting system's capability. Assess complete item geometry and trial the proposed loading method.

Q How do I prevent the shredder from becoming a production bottleneck?

Compare sustained trial output with both upstream supply and downstream handling capacity. Include feed interruptions and discharge constraints. A brief peak-throughput demonstration is insufficient to establish the performance of an integrated production line.
