Huashengming Heavy Industry’s crusher run limestone product line centers on double-roll crushers as core equipment, complemented by efficient grading crushers and other supporting machinery. Tailored to limestone characteristics—medium hardness and brittle material—it delivers highly efficient and energy-saving crushing solutions.

1. Core Technical Advantages
High Efficiency, Energy Savings, and Particle Size Control
Compression Crushing Principle: The double-roll crusher crushes limestone through dual-roll compression, achieving 30%-50% lower energy consumption than impact-type equipment, with power consumption per ton of material at just 1-2 kWh.
Hydraulic Intelligent Gap Adjustment: One-button roll gap adjustment (1-20mm) precisely controls output particle size (e.g., 1-3mm fine sand), with under-crushing rate <10%, meeting high-standard requirements for cement, aggregates, etc.
Wet Material Adaptability: Enclosed design + screenless structure (two-stage crusher) handles limestone with moisture content ≤35%, preventing blockages.
Wear Resistance & Durability
Patented Roller Shell Material: High-chromium manganese steel + rare metal alloy (patent pending), with compressive strength ≤160MPa. Service life reaches 2-3 years, reducing maintenance costs by over 30%.
Overload Protection: Hydraulic spring system automatically retracts rollers upon encountering hard objects, preventing equipment damage.
Environmental Protection & Intelligence
Dust & Noise Control: Enclosed crushing chamber + dust shield design, dust emissions <10mg/m³, noise ≤85dB.
PLC Control System: Supports remote monitoring and automatic lubrication, reducing manual intervention.
2. Main Equipment Models and Applications
Huashengming limestone crushers are categorized into three production capacity tiers. Users may select spring-type (economy model) or hydraulic-type (smart model) based on scale:
| Model Series | Representative Model | Production Capacity (t/h) | Application Scenarios | Core Advantages |
|---|---|---|---|---|
| Small Equipment | 2PGT400×400 | 2-20 | Start-up sand plants, small-scale sand production | Low investment |
| Medium Equipment | 2PGY1000×800 | 20-80 | Conventional aggregate lines, auxiliary crushing for cement plants | Hydraulic gap adjustment, uniform particle size |
| Large Equipment | 2PGY1800×2000 | 300-400+ | Large-scale mining intensive production | Fully automatic CNC control, remote monitoring |
| High-Power Classifying Crusher | Custom Model | 100-150 | High-moisture limestone, impurity-containing materials | Integrated screening and crushing, reduced over-grinding |
3.Crusher Run Limestone Industry Applications and Case Studies
Cement Production
Scenario: Fine crushing limestone to 1-3mm to enhance raw material reaction efficiency.
Solution: 2PGY1000×800 hydraulic double-roll crusher. After implementation at a cement plant, crushing efficiency increased by 40% while energy consumption decreased by 30%.
Construction Aggregates
Scenario: Crushing limestone into 0-5mm premium sand for high-strength concrete.
Solution: 2PGY1800×2000 delivers well-rounded particle shapes with under-crushing rate <10%, meeting requirements for high-speed rail and expressway projects.
Environmental Recycling
Scenario: Recycling limestone components from construction waste.
Solution: Two-stage crusher processes mixed materials without screen bottoms, automatically separates rebar, achieving 90% recycled aggregate utilization rate.
