1. Core Technical Features of Roller Crushers
Wear-Resistant Roller Shell Technology
Utilizing high-manganese steel composite casting, the roller shell lifespan reaches 2-3 years (compared to 6-12 months for standard equipment), reducing replacement costs.
Roller shell surfaces can be customized as smooth, ribbed, or toothed to accommodate varying material hardness.
Intelligent Hydraulic System
Dynamic Pressure Compensation Technology: Automatically adjusts inter-roller pressure based on material hardness to enhance crushing efficiency.
Integrated Hydraulic Spring Protection: Automatically retracts upon encountering non-crushable objects (e.g., metal blocks) to prevent equipment damage.
Energy-Efficient and Eco-Friendly Design
Low over-crushing rate (uniform final particle size) reduces energy consumption by 30% compared to traditional equipment.
Equipped with dust removal and noise reduction devices to meet environmental standards.
2. Main Product Series and Parameters
Huashengming roller crushers include single-roller, double-roller (twin-roller), and four-roller types to meet diverse crushing needs:
| Model | Processing Capacity | ?Feed Size | Output Particle Size | Motor Power | Application Scenarios |
|---|---|---|---|---|---|
| 2PG-750×500 (Twin Roll) | 50-100 t/h | ≤50mm | 1-3mm | 22kW×2 | Fine crushing of limestone and river pebbles |
| 12-50t/h Light Roller Crusher | 12-50 t/h | ≤250mm | 1-12mm | 55kW×2 | Power plant slag and oil shale |
| Four-Roll Crusher | 180-220 t/h | 700-950mm | 30-200mm | ?Custom Dual Motors |
High-efficiency crushing of coal and coke
|
| Hydraulic Twin Roll Sand Maker | 100-200 t/h | ≤100mm | 0-5mm | 37kW×2（Custom） | Manufactured sand production (e.g., bluestone, basalt) |
Note:
Double-roll crusher: Crushing ratio 1:5–1:7, compact structure, suitable for small-to-medium-scale production.
Four-roll crusher: Two pairs of rolls arranged vertically for primary + secondary crushing, achieving higher crushing ratios, ideal for large-scale processing of hard materials.
