Double Shaft Shredder for Tires, Metals, E-Waste, Plastics & More

Product Overview

A double shaft shredder uses two counter-rotating shafts to pull in and shear bulky feedstock at low speed. URIDGE configures the drive, knives, shaft speed and discharge arrangement after reviewing the material and required size reduction.

How the Double Shaft Shredder Works

The shredder is driven by electric motors and gear reducers. Common main-shaft speed is 10–30 RPM; the selected speed and drive configuration depend on the material and project requirements.

The machine does not use a screen. After the two shafts shear and tear the feedstock, the material discharges directly from below the shredding chamber. Final piece size and shape therefore depend on the material, knife geometry, shaft arrangement and operating conditions rather than a screen opening.

Current Monitoring and Automatic Reverse

The control system monitors motor current. When motor overload or excessive load is detected, the shafts reverse automatically to release the load and then resume forward rotation. Current limits and reverse timing are set for the selected motor, gearbox and material; this function manages overload conditions but is not an unconditional guarantee against every blockage or foreign object.

Confirmed Materials and Selection Boundaries

Project-specific double-shaft configurations can be provided for:

• Waste plastics
• Rubber tires
• Wood
• Metals
• Cables
• Electronic waste

Knife material, hardness and wear resistance are selected according to the feedstock. One knife and drive configuration should not be assumed to cover every material. Large solid lumps are normally directed to a single-shaft shredder. Concrete, batteries, engines and complete vehicle bodies are not presented as confirmed applications.

Low-Noise Design

The low-speed drive and machine structure can be configured with noise reduction in mind. Actual sound level depends on the material, loading method, enclosure, foundation and operating conditions; no fixed decibel value or unconditional noise performance is claimed.

Configuration Information to Prepare

To assess a double-shaft shredder, please send:

• Material type, composition and photographs
• Maximum feed dimensions and weight
• Metal, mineral or other contamination
• Required size reduction and downstream process
• Required throughput and operating hours
• Feeding and discharge method
• Local power supply and available layout

Material testing may be required for difficult, mixed or unfamiliar feedstock. You can request a technical review or use the WhatsApp contact on this page to start.
