1. Core Technology and Performance Advantages
Crushing Principle
Dual-Roller Synergy: Two horizontally mounted toothed rollers rotate in opposite directions, utilizing impact shearing and tensile forces to fracture material along weak points. This reduces energy consumption and prevents over-crushing.
Synchronized Screening: Crushed material is discharged through gaps between rollers and comb plates on side walls. Qualified particles are rapidly separated, avoiding re-crushing and boosting output.
Intelligent & Safety Design
Overload Protection: Dual safeguards with hydraulic coupling + sensors prevent power overload.
Automated Control: Hydraulically adjustable tooth pitch, centralized bearing lubrication, and remote monitoring support.
Wear Resistance & Environmental Protection
Optimized Tooth Profile: High-chromium manganese steel plates/wolf-tooth design ensure >2-year lifespan with compressive strength ≤260MPa.
Low Pollution: Enclosed structure + dust removal system, noise ≤85dB, dust concentration <20mg/m³²⁶.

3. Typical Application Scenarios and Effects
Construction Waste Recycling (Cangzhou Case)
Equipment: 2PGY750×500 (similar to 625-2000 model)
Results:
95% rebar recovery rate; aggregate (≤12mm) used for road subbase, reducing new material costs by 30%;
Comprehensive processing cost reduced to ¥60/ton (vs. ¥180/ton for landfill) 2.
Raw Coal Crushing in Coal Mines (Shanxi Case)
Equipment: 850-3000 model
Results:
Crushes raw coal containing gangue to 50mm, reducing over-crushing rate by 40% and increasing production capacity by 25%;
Hydraulic couplers minimize failure downtime, lowering annual maintenance costs by 15%.
