1. Core Technology: Key Advantages in Aggregate Crushing
Precise Particle Size Control
Hydraulic Intelligent Gap Adjustment: Double-roll crushers (e.g., HR-1200×1000) feature one-touch hydraulic adjustment of the roll gap (1-20mm), ensuring uniform output particle size (0-3mm, 0-5mm) with an over-crushing rate <10%, meeting high-grade concrete aggregate requirements.
Dual-stage screening adjustment: The dual-stage crusher flexibly controls output particle size (down to below 2mm) by adjusting the gap between secondary screen plates, accommodating diverse needs from roadbed filling to premium brick manufacturing.
Wear Resistance & Extended Lifespan
Patented Roller Shell Material: High-chromium manganese steel + rare metal alloy roller shells (patent pending) deliver compressive strength ≤160MPa and 2-3 year service life, reducing maintenance costs by over 30%.
Dual-stage crusher hammers: Special alloy composite hammers resist wear and impact, handling high-hardness materials like furnace slag and steel slag.
High Adaptability Design
No wet material clogging: The double-stage crusher’s screenless bottom structure processes coal gangue and construction waste with moisture content ≤35%, preventing adhesion and blockages.
High-efficiency hard rock crushing: Roll crushers compressively crush granite and quartzite (Mohs hardness ≥7), achieving hourly outputs up to 400 tons.

3. Industry Applications and Case Studies
Hard Rock Aggregate Production
Scenario: Crushing granite and basalt into 0-5mm manufactured sand for high-speed rail and expressway projects.
Solution: HR-1200×1000 double-roll crusher delivers well-rounded output with under-crushing rate <10%, replacing natural sand.
Construction Waste Recycling
Scenario: Converting waste bricks/tiles and concrete blocks into recycled aggregate (10-30mm).
Solution: Screenless processing with automatic rebar separation achieves 90% recycling rate for permeable bricks or roadbed materials.
Industrial Solid Waste Resource Recovery
Application: Crushing furnace slag and steel slag into 3-5mm fine particles for eco-brick production.
Solution: Dual-stage crusher with twin rotor design employs “tear-and-refine” processing for materials exceeding Mohs hardness level 7, enhancing value-added potential.
