Huashengming double roll crushers feature wear resistance, durability, energy efficiency, and flexibility as their core advantages, serving applications ranging from small sand plants with an hourly output of 2 tons to large-scale mining projects processing up to 400 tons per hour.
1. Double Roll Crushers Product Type and Core Features
Spring/Hydraulic Double-Roll Crusher (Flagship Model)
Working Principle: Achieves medium and fine crushing by squeezing materials through two parallel rollers rotating in opposite directions. Output particle size is precisely controlled by adjusting the roller gap (adjustable from 1–12mm).
Core Advantages:
Exceptional Wear Resistance: Roller shells utilize high-chromium manganese steel (patented rare-metal alloy formulation) with a lifespan exceeding 2 years and compressive strength ≤260MPa.
Energy Efficiency & High Productivity: Lower energy consumption per unit compared to hammer crushers. Hydraulic models feature one-touch start/stop and remote monitoring for high automation.
Low Maintenance Costs: Compact structure with minimal wear parts. Dual spring/hydraulic overload protection minimizes downtime.
Double-Tooth Roller Crusher (Special Material Processing)
Applications: Specifically engineered for brittle materials (e.g., waste asphalt, construction debris, coal gangue). Tooth profiles (wolf teeth/wave teeth) enhance shearing force while reducing over-crushing.
Environmental Features: Low-dust, low-noise design meets green production standards, particularly suitable for asphalt recycling and resource recovery projects.

Application Scenarios: Specifically designed for brittle materials (e.g., waste asphalt, construction debris, coal gangue). Features a tooth-shaped structure (wolf-tooth design).
Note: Pricing varies based on configuration (high/low spec, intelligent systems) and customization requirements. Hydraulic models cost 30%-50% more than spring-loaded models.
3.Double Roll Crushers Application Scenarios & Materials
Material Range:
Medium-low hardness materials: river pebbles, limestone, coal gangue, shale (compressive strength ≤260MPa).
Special materials: waste asphalt, construction waste, wet sticky coal slurry (dual-tooth roller models specialized).
Typical Applications:
Aggregate plants: Small-scale screening with 400 series, medium-scale with 800 series, large-scale with 1000 series and above.
Resource recovery: Construction waste crushing (tooth roll crushers preserve gradation characteristics and reduce fine powder generation).
Mining pre-processing: Following jaw crusher primary crushing, feed into for secondary/tertiary crushing to enhance product uniformity.
