A Double Roll Crusher is a robust machine used for secondary and tertiary crushing of medium-hard to soft materials such as coal, limestone, clay, and minerals. Below are the typical technical specifications for a double roll crusher:

General Specifications:
1. Feed Size: Up to 500 mm (varies by model)
2. Product Size: 2–10 mm (adjustable via roll gap)
3. Capacity: 5–500 TPH (depends on material and roll size)
4. Roll Diameter: 300–1500 mm
5. Roll Width: 200–2000 mm
6. Power Requirement: 5–200 kW (varies with size and material hardness)

Mechanical & Operational Features:
– Roll Speed: 50–300 RPM (adjustable based on application)
– Crushing Mechanism: Two counter-rotating rolls with teeth, smooth, or corrugated surfaces
– Gap Adjustment: Hydraulic or mechanical system for precise control of output size
– Drive System: Electric motor with V-belt or gear reducer

Material & Construction:
– Roll Material: High manganese steel, hardened steel, or alloy steel for wear resistance
– Frame Construction: Heavy-duty steel with anti-vibration mounts
