1. Dual-stage screenless crushing technology (Core model: SCF series)
Wet Material Non-Blocking Design
Eliminates traditional screen structures by employing dual-rotor serial crushing (primary coarse crushing + secondary fine crushing), completely resolving blockage issues with high-moisture concrete and clay-like materials.
Case Study: Processed construction waste with 15% moisture content, achieving continuous operation without failure and stable output particle size ≤3mm.
High Efficiency & Single-Pass Processing
Dual rotors work synergistically to achieve compliant output (80% particles ≤2mm) after two crushing stages, eliminating the need for refeeding and reducing energy consumption by 15–30%.
Capacity Comparison: The SCF1000×800 model achieves 180 tons/hour, representing a 40% efficiency gain over single-stage crushers.
Hydraulic Quick-Opening Maintenance System
Hydraulically driven housing opens/closes with one button. Maintenance of hammers/liners requires no complete machine disassembly, reducing maintenance time by 70% and labor costs by 50%.
2. Toothed Roller Crushing Technology (Core Models: 2PGY Series, Four-Roller Crushers)
Precise Particle Size Control
Hydraulically adjustable roller gap (1–50mm) enables stable output particle size control within 1–3mm, meeting stringent recycled aggregate standards (e.g., roadbed fill, precast components).
Technical Highlights: Real-time sensors monitor material hardness, automatically adjusting pressure to prevent overload, reducing failure rates by 30%.
Wear-Resistant & Long-Life Design
Roll shells feature high-chromium alloy + tungsten carbide coating (hardness HRC62), delivering over twice the lifespan of standard materials. Exceeds 2 years when processing granite concrete.
Modular tooth plate design allows replacement of individual plates after localized wear, reducing maintenance costs by 40%.
Hard Rock Processing Capability
Dual-tooth/quad-tooth roller structures apply combined shear, tensile, and compression forces to concrete. Processes materials with crushing strength ≤300MPa (e.g., demolition waste containing rebar) with feed sizes up to 600mm.
3. Environmental and Intelligent Innovations
Low-Noise Dust Reduction System
Enclosed chamber + dust extraction port, dust emissions ≤10mg/m³, noise control <85dB, compliant with green mining standards.
Remote Intelligent Control
Supports mobile app remote monitoring of operating parameters and fault alerts (e.g., bearing temperature rise, abnormal vibration), enabling unmanned production.
Power-Adaptive Energy Efficiency
Customized tractor power interfaces (55–150 horsepower) prevent power wastage, delivering 20–30% lower energy consumption than traditional equipment in field tests.
