Hydraulic Double Roller Technology Applied in 150-200 T/H Coal Processing Line
Optimizing grain size distribution while preventing blockages from high-moisture feed.

2PGY1500×1200
Operational Pain Points: Excessive Fine Slime & Slurry Accumulation
Our client, a large-scale coal preparation and chemical plant, was previously using a traditional hammer mill to process raw coal for thermal boiler feeding. However, they faced two critical bottlenecks that severely impacted profit margins:
The impact action of the hammer mill generated over 25% coal powder (fines under 3mm), which burned too quickly and caused massive economic loss.
During the rainy season, raw coal moisture soared to over 12%, completely choking the crushing chamber and forcing shutdowns every few hours for manual cleaning.

Technical Upgrade: Implementing the 2PGY1500×1200 Heavy-Duty Roller System
After diagnosing the precise physical material properties, our technical team configured the 2PGY1500×1200 Fully Hydraulic Double Roller Crusher upgraded with customized high-chromium alloy roller shells.
Unlike destructive impact crushing, the counter-rotating rollers utilize low-speed, high-torque static pressure extrusion. The raw coal is drawn smoothly between the synchronized rollers, crushed instantly along its natural geological fractures, and discharged cleanly via gravity.

Performance Metrics: Lower Power Consumption & Enhanced Cubical Yield
Since industrial commissioning, the heavy-duty plant has achieved stable 24/7 continuous operation with optimized output metrics:
✓
The over-crushing rate dropped drastically from 25% to under 5%, significantly increasing the total output value of high-premium sized coal.
✓
Even during heavy rainfall and handling 12%+ high-moisture feed, the continuous self-cleaning movement of the dual rollers completely prevented structural sticking.
✓
The intelligent automatic hydraulic system drastically optimized electricity consumption, saving thousands of dollars in monthly utility expenditures.
