Product Overview
The Hydraulic Double Toothed Roller Crusher is an industrial-grade, high-efficiency crushing machine engineered with state-of-the-art hydraulic control systems. Specifically designed for the primary, secondary, or fine crushing of medium-hard to complex raw materials, it utilizes two horizontally mounted, counter-rotating alloy toothed rollers to deliver exceptional high-throughput performance.
Its specialized tooth profile combines powerful extrusion, shearing, and splitting mechanisms simultaneously. This unique kinematic design makes it the industry’s premier choice for processing sticky, high-moisture, and high-mud content ores that typically blind or clog conventional jaw or cone crushers. Assisted by an intelligent responsive hydraulic configuration, it ensures unparalleled operational safety, continuous stability, and exceptionally low lifecycle costs.
Tailored to Your Specifications: We offer comprehensive customization for the tooth layout, geometry, and surface metallurgy. The size, height, and alignment of the teeth are precision-engineered based on your specific mineral type, hardness profile, moisture content, and targeted output distribution to optimize operational capacity.

Core Advantages
1. Intelligent Hydraulic Overload Protection & Instant Reset The integrated smart hydraulic system instantly senses uncrushable tramp materials (e.g., stray iron pieces). It automatically retracts the movable roller to smoothly discharge the foreign object and resets immediately to prevent structural damage. The roller clearance gap can be adjusted under load via the hydraulic panel without stopping production.
2. Anti-Clogging & Self-Cleaning Geometry The interlocking, non-blind design of the counter-rotating serrated rolls guarantees continuous self-cleaning action. It completely eliminates material bridging, packing, and accumulation issues, facilitating smooth, continuous feeding even when processing materials with extreme moisture or high mud saturation.
3. Extended Component Lifespan & Modular Maintenance The crushing teeth are cast from proprietary wear-resistant formulas including high-chromium and manganese steel alloys, delivering a service life 3 to 5 times longer than standard material segments. The highly flexible modular tooth segments can be replaced quickly on-site, minimizing operational downtime and labor costs.
4. High-Quality Cubic Output with Minimal Fines By applying targeted point-load splitting rather than excessive grinding, the crusher yields a highly consistent, cubic product. The percentage of elongated or needle-like flakes and over-crushed fines is significantly reduced, strictly satisfying demanding international aggregate specifications.

Working Principle
The operation relies on a synchronized combination of high-torque extrusion, shearing, and localized tensile splitting. Powered by dual high-efficiency electric motors via heavy-duty reducers, the two horizontally parallel toothed rollers rotate inward in opposite directions at optimized operational speeds. As raw material enters the top of the crushing chamber, it is immediately gripped by the rotating heavy teeth. The overlapping tooth arrangement subjects the material to concentrated forces, cracking it swiftly. Once broken down smaller than the preset roll gap, the finished particles are discharged smoothly below by gravity, maintaining consistent sizing throughout the campaign.
