Double shafts waste tyre shredding machine is used to crush pre-treated waste tires into 30-80mm rubber blocks at room temperature the equipment is combined with circular rolling screening and no additional screening equipment is required crushing and screening are integrated to achieve the required size at one time the double shafts shredder machine can also be customized according to customer requirements.
Feed Size:750-1350mm
Output Size:30-80mm
Capacity:1000-6000kg/h
Double shafts waste tyre shredding machine is a core equipment for large-scale waste tire recycling, designed to shred tires into 30-80mm rubber blocks through the shearing and tearing action of two counter-rotating shafts. It efficiently handles tires with steel wire or fiber reinforcement, serving as the primary crushing stage in recycling lines for rubber granules, reclaimed rubber, or pyrolysis materials.
Working Principle
Dual-shaft Co-crushing
Two main shafts equipped with interlaced blades rotate in opposite directions, breaking down tires through three synergistic actions: shearing, tearing, and crushing.
Intelligent Control System
Equipped with a PLC automatic monitoring system that detects overloads (e.g., steel wire entanglement) and triggers automatic reverse rotation to prevent equipment jams.
Grading Crushing Process
Crushed materials pass through a screening mesh. Particles that do not meet the required size are automatically recycled for reprocessing, ensuring uniform output granularity.
Core Advantages
High-efficiency Processing Capacity
Single-unit hourly output ranges from 1-5 tons (depending on tire specifications). Capable of continuous processing of large tires such as truck and engineering tires, with 40% higher efficiency than single-shaft models.
Low-energy Design
Features a hydraulic-assisted feeding system to reduce motor load, combined with a variable-frequency speed control system, reducing energy consumption by 25% compared to traditional models.
Impact-resistant Structure
Blades made of high-chromium alloy (HRC 58-62) and main shafts subjected to forging and quenching treatments. Capable of withstanding friction and impact from steel wires, extending replacement intervals to 8,000 hours.
Environmentally-friendly Noise Reduction Design
Fully enclosed soundproof housing + shock-absorbing base, reducing operational noise to <85dB. Equipped with a dust collection system to control dust emissions to ≤10mg/m³.
