What Is The Difference Between A Hammer Crusher And A Roller Crusher?Hammer crushers and roller crushers are commonly used crushing equipment in mining, building materials, and other industries. They exhibit significant differences in working principles, suitable materials, and discharge characteristics. As a renowned domestic manufacturer of crushing equipment, Huashengming offers products with distinct advantages in both types of machinery.
Roller Crusher
1. Core Differences Comparison
| Comparison Dimensions | Hammer Crusher | Roller Crusher |
|---|---|---|
| Working Principle | High-speed rotating hammers impact the material, supplemented by shearing and grinding. | Two rollers rotate in opposite directions to compress the material, primarily relying on hydrostatic crushing. |
| Suitable Materials | Medium-hard brittle materials (limestone, coal gangue, gypsum), compressive strength ≤100 MPa, moisture content <15% | Medium-hard materials (river pebbles, granite, coal) with compressive strength ≤160 MPa and moisture content ≤35% remain operational. |
| Feed Particle Size | Large (600–1800 mm) | Smaller (≤40–150 mm) |
| Discharge Characteristics |
Particle size is uneven, prone to over-grinding (high powder content)
|
Particle size is uniformly controllable (adjustable from 1–20 mm), with a high proportion of cubic particles and low over-grinding rate. |
| Output and Energy Consumption | High production capacity (up to 3,000 tons per hour), relatively high energy consumption per unit | Medium output (5–400 tons/hour), with energy consumption per unit reduced by 30%–50% (1–2 kWh electricity consumption per ton of material processed). |
| Wear Resistance and Maintenance | Hammer heads and screen plates wear out quickly and require frequent replacement (especially when processing hard materials). | The roller skin is made of high-chromium manganese steel + rare alloy (patented material), with a service life of 2–3 years and low maintenance costs. |
| Environmental Performance | High noise levels (≥120dB), excessive dust | Noise ≤ 85 dB, sealed dust-proof design, minimal dust accumulation |
2. Huashengming Product Features
Core Advantages of Huashengming Roller Crushers
Patented Wear-Resistant Technology: Roller shells utilize high-chromium manganese steel + rare metal alloys, achieving a lifespan exceeding 2 years with compressive strength ≤160MPa.
Intelligent Control: Hydraulic system enables one-button adjustment of roller gap (1–20mm), precisely controlling output particle size. Select models support remote monitoring.
High Adaptability: No clogging with wet materials (moisture content ≤35%) or dry materials, ideal for construction waste recycling and high-moisture coal gangue crushing.
Energy-Efficient: Extrusion crushing minimizes over-grinding, reducing subsequent grinding energy consumption by 30%-50%, aligning with the “more crushing, less grinding” trend.
Features of Huashengming Hammer Crusher
Two-stage crushing design (e.g., double-stage hammer crusher): Upper and lower rotors connected in series. Screenless structure prevents wet material blockage, suitable for coal gangue and shale.
Wear-Resistant Hammer Heads: Alloy hammers offer high impact resistance but require periodic replacement (recommended inspection every 3–6 months).
High-Capacity Performance: Models like the Φ1600×1600 achieve hourly outputs of 220–280 tons, making it suitable for coarse crushing in large-scale aggregate production lines.
