1. Working Principle
Dual-Roller Compression Mechanism
The equipment consists of two parallel roller shafts (fixed roller and movable roller) driven by motors to rotate at different speeds in opposite directions. Materials fed into the gap between the rollers from above undergo high-pressure compression and shear forces, resulting in crushing to the target particle size.
Particle Size Control: Precise output size is achieved by adjusting the gap between the rollers (hydraulic or spring system). Increasing the gap produces coarser output, while decreasing it yields finer output.
Low-Speed, High-Torque Design: Reduces energy consumption and equipment wear while ensuring uniform material crushing.
Auxiliary Crushing Action
Beyond compression, material undergoes kneading and shearing between roller teeth or liners, making it particularly suitable for fine crushing of brittle materials (e.g., coal, ore).
2. Applicable Materials and Scenarios
Material Types
Medium-hard brittle materials: river pebbles, cobblestones, limestone, coal, slag, coke, etc.
Limitations: Not suitable for highly plastic or sticky materials (e.g., wet clay). Feed size typically requires ≤80mm.
Application Industries
Aggregate Production: Sand manufacturing (river pebbles/cobbles yield uniformly graded sand meeting construction standards).
Mining & Metallurgy: Crushing iron ore, quartzite, dolomite, etc.
Environmental Processing: Construction waste recycling, power plant slag crushing.
3. Core Application Advantages
High-Quality Output
Uniform, controllable particle size (1–50mm), low over-crushing rate, resulting in well-formed, well-graded finished aggregates.
Durability and Low Maintenance
High-chromium manganese steel roll liners provide 1–2 year service life; minimal wear parts reduce maintenance costs.
Modular design enables rapid component replacement, minimizing downtime.
Energy Efficiency & Environmental Protection
Energy consumption reduced by over 30% compared to impact crushers, with low noise and dust emissions (sealed structure + low-speed operation).
Intelligent Operation
New models feature hydraulic systems and smart controls for real-time monitoring of temperature, pressure, and other parameters, automatically adjusting roller clearance and rotational speed.
