1. Dust Control Technology: Three-Tier Treatment System
Source Dust Suppression
Pre-Humidification System: Ultrasonic atomizing nozzles (water pressure ≥7MPa) installed at feed points precisely control material moisture content between 8%-12%, reducing PM2.5-level particulate generation at source. Measured dust concentration reduction reaches 76% (e.g., limestone crushing from 89mg/m³ to 21mg/m³).
Dust Suppressant Spraying: Utilizes polymeric binding agents automatically sprayed at belt transfer points, boosting dust settling rates by 70%. Increases material handling costs by only 0.3-0.8 yuan per ton.
Process Containment
Chamber Negative Pressure Sealing: Installs extraction hoods (air velocity ≥18m/s) and labyrinth seals (gap <1mm) atop jaw/cone crushers, creating a -15Pa to -30Pa micro-negative pressure environment that reduces dust escape rates below 5%.
Modular Fully Enclosed Canopy: Utilizes an aluminum-zinc-coated steel plate + PVDF membrane composite structure (light transmittance >80%) covering the entire crushing and screening process, balancing maintenance accessibility with dust containment effectiveness.
End-of-Line Purification
Intelligent Pulse-Jet Baghouse Dust Collector: Utilizes variable-frequency drive fans and differential pressure sensors (automatic cleaning at resistance >1200Pa) to maintain stable emissions ≤10mg/m³ (meeting GB16297 standards), extending filter bag lifespan to over 8000 hours.
Dust Resource Utilization: Over 85% of collected dust meets construction sand standards and is pneumatically conveyed for reuse in concrete production; dust exceeding heavy metal limits is handled by specialized units.
2. Noise Reduction Technology: Five-Dimensional Collaborative Noise Reduction
Source Optimization
Nano-ceramic composite lining plates: Microporous energy-absorbing structure reduces material impact noise by 12-18dB. Combined with optimized crushing chamber curvature, friction noise is reduced by 9dB.
Intelligent Load Sensing: Dynamically adjusts motor speed to reduce no-load energy consumption and noise.
Transmission Blocking
Modular Soundproof Enclosure: Utilizes a “3mm steel plate + 50mm acoustic cotton + 2mm perforated aluminum plate” sandwich structure, achieving 36dB sound insulation. The ventilation system incorporates impedance composite silencers, limiting exhaust noise to ≤70dB.
Floating Installation Platform: Rubber-spring composite isolators reduce vibration transmission by 75%, lowering equipment vibration intensity from 8.2 mm/s to 2.5 mm/s.
Intelligent Monitoring
Deployed multi-parameter sensor networks monitor noise and vibration metrics in real time. AI models predict failures like bearing wear, while digital twin platforms optimize noise reduction strategies.
Patented Technology Applications
Examples include Zhejiang Youxin’s patented “Crusher Noise Reduction Structure,” which blocks noise propagation pathways by incorporating soundproof chambers within the feed housing.
3. Resource Recycling Innovations
Tunnel Excavation Waste Utilization
Excavated tunnel debris (e.g., feldspar sandstone with 87MPa compressive strength) is processed on-site into construction aggregates, forming a closed-loop chain of “excavation-processing-local supply.” This reduces transportation costs and avoids landfill occupation (Case Study: Jia-Ru Expressway project saved over 100 million yuan).
Ecological Restoration with Overburden Soil
Overburden soil from mining operations is repurposed to backfill historic mine pits (e.g., Loudi Wanqiao Mining Area in Hunan collaborated with a closed brick factory, using 1 million m³ of topsoil for ecological restoration). This reduces the footprint of waste dumps and enhances resource utilization.

4. Energy-Saving and Consumption-Reducing Technologies
High-Efficiency Transmission Design
Huashengming limestone crushers optimize rotor structure, reducing linear speed by 20%-25% and cutting unit energy consumption by over 30%, achieving a crushing ratio of 5:1.
Clean Energy Application
Promotes hybrid-electric transport vehicles and downhill belt potential energy generation technology, harnessing elevation differences within mining areas for power generation.
Wear-Resistant Material Upgrades
Employs high-chromium-molybdenum-vanadium alloy hammer plates (50% longer lifespan) and ZTA ceramic distribution cones (6x increased lifespan), reducing component replacement frequency and resource consumption.
