Hydraulic Double Roller Crusher
Traditional hammer mills or impact crushers rely on high-speed beating, which inevitably creates excessive coal dust (often over 25% fines) and easily chokes up during the rainy season. To solve this, APEX engineers implement a two-pronged technical upgrade:
- 1. Switch to Static Pressure Extrusion: APEX Hydraulic Double Roller Crushers utilize low-speed, high-torque rollers. Coal is drawn in and crushed along its natural geological fractures instantly, dropping the over-crushing fines rate from 25% to under 5%.
- 2. Continuous Self-Cleaning Action: For wet materials with 12%+ moisture, the constant counter-rotating movement of the dual rollers combined with real-time hydraulic gap tracking eliminates material accumulation, ensuring zero clogging and stable 24/7 continuous operation.
Real-World Proof: In our recent 150-200 T/H coal preparation project, switching to the APEX 2PGY1500×1200 series not only eliminated seasonal shutdowns completely but also saved the client up to 30% in direct power consumption.
