Huashengming small concrete crusher primarily feature two main types: double-roll and hammer crushers. With their compact structure, high wear resistance, and excellent cost-performance ratio, they deliver outstanding performance in scenarios such as construction waste recycling, old building demolition, and road renovation.
Double-Roll crusher
1. Core Types and Technical Features
Double-Roll Crusher (Flagship Model)
Working Principle: Dual counter-rotating rollers compress concrete blocks. Hydraulic systems adjust output particle size (adjustable 1–12mm) for medium-fine crushing operations.
Core Advantages:
Wear Resistance: Roll shells utilize high-chromium manganese steel (containing rare metals) with a lifespan exceeding 2 years, capable of processing concrete blocks ≤260MPa hardness.
Low-Dust Environmental Protection: Built-in dust removal system maintains PM10 concentration <50μg/m³ during operation with noise ≤85dB, suitable for urban construction.
Intelligent Control: Hydraulic models (e.g., 2PGY series) support remote monitoring and automatic particle size adjustment, reducing manual intervention.
Hammer Crusher (Suitable for Wet/Sticky Materials)
Special Design: Screenless structure + dual-rotor crushing, specifically targets high-moisture concrete fragments (e.g., slurry-laden demolition waste), with strong anti-clogging capability.
Crushing Effect: Output particle size ≤3mm (80% ≤2mm), no pre-treatment required for wet materials.
