Huashengming limestone crusher machine are primarily divided into two major series: double-roll crushers and double-stage crushers. Both are optimized for limestone characteristics—its tendency to pulverize and significant moisture content fluctuations—striking a balance between high-efficiency crushing and cost control.
limestone crusher machine
1. Double-Roll Crusher (Main Model)
Working Principle: Dual-roll compression crushing. Precisely controls output particle size (1-3mm fine sand to 5-40mm aggregate) by adjusting the roll gap (1-20mm), preventing over-crushing.
Core Advantages:
Wear Resistance & Durability: Roll shells utilize high-chromium manganese steel + rare metal composite materials (patented technology), ensuring over 2 years of service life (processing capacity exceeding 30,000 tons).
Wet Material Non-Blocking: Anti-blocking structure + anti-slip roll surface treatment support direct crushing of materials with up to 15% moisture content.
Energy Efficiency & Environmental Protection: Energy consumption reduced by 15%-20% compared to traditional hammer crushers; enclosed operation reduces dust by 60%.
Applications:
Small units: Gold mining trials, construction waste recycling (e.g., fine crushing of waste concrete);
Large hydraulic units: Large-scale aggregate production (e.g., granite, basalt).
2. Two-stage Crusher (High-Moisture Material Specialized)
Working Principle: Dual-rotor series design (no screen bottom). Material undergoes two-stage hammer crushing, completing coarse and fine crushing in one pass with output ≤3mm.
Core Advantages:
Clog-Free in Wet/Sticky Materials: Screenless structure eliminates blockages, ideal for high-clay limestone.
Dual-Function in One Machine: Replaces jaw crusher + fine crusher combo, saving over 30% in equipment investment.
Energy-Efficient Operation: Dual rotor coordination reduces energy consumption by 20% (e.g., 800×600 model total power 100kW).
Application Scenarios:
Small-to-medium sand and gravel plants: Produces qualified aggregates with a single machine, simplifying production lines.
Cement raw material crushing: Processes high-moisture materials like limestone and gypsum.
