Product Introduction
Our Double Roller Crusher for Industrial Waste is a heavy-duty, high-torque shredding and crushing system specifically designed to handle complex, hazardous, and non-hazardous industrial solid waste (ISW). Industrial waste streams are notoriously challenging due to their unpredictable mix of high-hardness solids, tough polymers, and abrasive compounds. This advanced twin-roll crusher delivers exceptional performance when processing materials like industrial slag, factory chemical waste cakes, discarded pallets, electronic waste (E-waste), rubber scraps, fiber-reinforced plastics, and manufacturing rejects. It serves as an indispensable core machine for bulk waste volume reduction, resource recovery lines, and refuse-derived fuel (RDF) preparation plants.
Technical Performance
Applicable Materials: Industrial metallurgical slag, chemical cakes, glass bottles, scrap plastics, electronics, carbon block residues, rubber, and mixed factory refuse.
Production Capacity: High-efficiency throughput ranging from 5 to over 80 tons per hour, depending on waste density and configuration.
Flexible Tooth Profiles: Available with smooth, corrugated, or heavy-toothed roller surfaces to match different material properties (shearing vs. crushing action).
Controlled Output Sizing: Feature an infinitely adjustable discharge gap, allowing operators to achieve fine crushing (down to 2mm) or coarse pre-shredding (up to 50mm) for optimal downstream sorting.
Material Resilience: Designed to handle complex mixtures containing both moisture and sticky substances without clogging or jamming.
Working Principle
The machine utilizes an aggressive, low-speed, high-torque counter-rotational mechanism to squeeze, shear, and fracture industrial waste:
Continuous Material Inflow: Raw industrial waste is fed via a hopper into the crushing chamber directly above the twin counter-rotating rollers.
Aggressive Grabbing & Shearing: For tough industrial waste, specialized toothed or textured rollers bite into the material, forcefully drawing it down into the crushing zone through high-friction mechanical grabbing.
High-Pressure Destruction: As the waste passes through the narrow gap between the two rollers, it is subjected to immense hydraulic-backed compression and tearing forces. Brittle materials (like slag and glass) shatter instantly, while tough materials (like plastics and composites) are sheared into smaller pieces.
Intelligent Tramp Release: If a non-crushable item (such as a solid steel block or thick machinery component) enters the chamber, the automated hydraulic or heavy-spring safety system immediately triggers. The movable roller retracts to discharge the object safely, then instantly resets to its original position to continue operations without human intervention.
Key Features & Advantages
High-Torque & Anti-Wrapping Design: Operating at low speeds with high torque, it easily tears through tough industrial fabrics and polymers. The integrated heavy-duty scrapers prevent flexible materials (like plastic film or rubber) from wrapping around the rollers.
Extreme Durability for Abrasive Waste: The outer shells of the rollers are engineered from specialized wear-resistant alloy matrices or tungsten carbide overlays, ensuring a prolonged service life even when crushing highly abrasive industrial slag.
Explosion-Proof & Sealed Enclosure: Designed with the strict safety requirements of industrial environments in mind, the crushing chamber can be fully sealed and equipped with dust suppression, odor control interfaces, or explosion-proof motors for hazardous chemical waste processing.
Energy-Efficient Drive System: Compared to high-speed hammer mills, the low-RPM double roller design reduces power consumption by up to 20% to 30% while delivering superior material reduction and reducing operational noise.
Smart PLC Overload Protection: Features an advanced automation panel that continuously monitors motor current. If a temporary blockage occurs, the system automatically reverses the rollers briefly to clear the jam before resuming forward crushing.
Applications: Highly recommended for industrial waste recycling centers, RDF/SRF (Refuse Derived Fuel) production lines, chemical and metallurgical plant waste processing, and co-processing facilities in cement kilns.
