Huashengming fine crushers leverage patented wear-resistant technology (roller skin/hammer head lifespan of 2–3 years), intelligent particle size control (hydraulic gap adjustment 1–20mm), and high adaptability (no clogging with wet materials, high efficiency with hard materials) as core advantages, covering all scenarios including sand and gravel aggregates, environmental recycling, and mining fine crushing. Model selection requires comprehensive consideration of material properties and production capacity. For small-to-medium-scale operations, dual-stage crushers or medium-sized double-roll crushers are preferred. For large-scale, intensive production lines, fully automatic hydraulic models are recommended.

I. Working Principle and Technical Features
Double-roll Fine Crusher (Main Model)
Working Principle: Material is crushed through dual-roll compression. The hydraulic system enables one-touch adjustment of the roll gap (1–20 mm), precisely controlling output particle size (e.g., 1–3 mm fine sand).
Wear-Resistant Technology: Roll shells utilize high-chromium manganese steel + rare metal alloy (patent pending), with compressive strength ≤160MPa and service life of 2–3 years, reducing maintenance costs by over 30%.
Advantages: Over-crushing rate <10%, uniform particle shape, power consumption 1–2 kWh/ton, achieving 30%–50% energy savings.
Two-Stage Screenless Fine Crusher (Specialized for Wet/Sticky Materials)
Innovative Design: Dual-rotor series structure with screenless anti-clogging capability, processes high-moisture sticky materials like coal gangue and shale with moisture content ≤35%.
Particle Size Control: Output ≤3mm (80% below 2mm), high crushing ratio, eliminating secondary crushing.
Models & Capacity:
600×400: 15–25 tons/hour, suitable for small construction waste processing plants.
1000×800: 60–90 tons/hour, ideal for coal mine backfilling projects.
Advantages: Alloy hammers offer high wear resistance and durability; modular design facilitates maintenance; low dust and noise levels.
Double-Tooth Roller Fine Crusher (Medium-Hard Brittle Materials)
Optimized Tooth Profile: Wolf-tooth/square-wave tooth design provides gentle compression, reducing over-crushing (fineness rate <10%) and preserving aggregate integrity.
Model & Parameters:
2PGY750×500: Capacity 15–30 t/h, discharge size 2–8 mm (adjustable), suitable for crushing coke and petroleum coke.
2PGY1000×700: Capacity 35–60 t/h, feed size ≤60 mm, suitable for metallurgical and refractory industries.
2. Technical Advantages and Innovations
Intelligent Control
Hydraulic models support remote monitoring and automatic lubrication, with precise gap adjustment (e.g., 1–3mm fine sand) to meet high-grade concrete aggregate requirements.
High Adaptability
Dry/Wet Versatility: Screenless design eliminates clogging in high-moisture materials (e.g., construction waste, coal slurry).
High-Hardness Efficiency: Delivers outstanding fine crushing performance for materials like granite and quartzite (Mohs hardness ≥7).
Energy Efficiency & Environmental Protection
Power consumption: 1–2 kWh per ton of material processed, achieving 30%–50% energy savings over traditional equipment.
Enclosed structure + dust extraction design: Noise level ≤85 dB, dust emissions <10 mg/m³.
