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 Should I choose the 3 kW or 5.5 kW motor?

Choose according to cutting resistance, feed thickness and the intended duty cycle. A larger motor does not automatically deliver proportionally higher throughput. Confirm that the reducer, shafts and protection settings match the proposed configuration.

Q What is the maximum feed size for the 150 model?

The listed chamber dimensions are not a guaranteed maximum feed size. Shape, wall thickness and the way material engages the cutters also matter. Submit the largest typical item, including its thickest section, for assessment.

Q Can the 150 model run on my local power supply?

The product page lists customizable voltage. Specify voltage, phase and frequency, then obtain written confirmation for the motor and control cabinet. Voltage customization alone does not confirm compatibility with a single-phase supply.

Q How should I compare the Mini and 150 models?

Compare usable feed dimensions, cutting resistance, required daily output and cleaning access. Test the same material under comparable feeding conditions. Select the configuration that meets your processing requirement without frequent interruptions or excessive manual preparation.
