Key Equipment
The Challenge: What the Client Needed
A major coal mining group in the Kuzbass region required a reliable upgrade.
They needed to process raw, blocky bituminous coal into precise sizes.
Their existing crushing machines suffered from two massive operational flaws.
First, the sticky coal fines frequently clogged the screening mesh.
This clogging triggered constant emergency stops to clean the equipment manually.
Second, the old crushers caused severe over-crushing, creating too much worthless coal dust.
The client demanded 100% compliance with strict export grain-size distribution standards.
The Solution: Sunwe Specialized Coal Crushing Line
Sunwe configured a specialized coal crushing line to maximize sizing accuracy.
We engineered the system to handle sticky materials without any clogging.
Step 1: Optimized Primary Crushing
Our heavy-duty, low-wear Impact Crushers handle the primary block reductions.
We adjusted the rotor speed to break large coal blocks gently.
This custom calibration minimizes over-crushing and reduces the generation of fine dust.
Step 2: Anti-Clogging Sizing
The crushed bituminous coal feeds directly onto high-capacity Linear Vibrating Screens.
We equipped these screens with specialized anti-blinding polyurethane mesh.
The linear motion moves sticky fines forward quickly, preventing any material build-up.
Step 3: Automated Dust Control
Enclosed belt conveyors transport the precisely sized coal to the stockyard.
Integrated mist sprayers suppress dust along the line to meet local environmental codes.
Performance Comparison
The table below illustrates the production efficiency before and after deploying Sunwe.
| Key Performance Indicator (KPI) | Previous Coal Plant | Sunwe Sizing System | Net Improvement |
| Hourly Output (TPH) | 420 t/h | 600 t/h | +42.8% Higher Volume |
| Export Sizing Compliance | 82% (Inconsistent) | 100% (Strict) | 100% Export Ready |
| Fine Dust Waste (Over-crushing) | 14% Loss | Under 4% | 71.4% Dust Reduction |
| Screen Clogging Incidents | 2-3 Times / Shift | 0 Times | Continuous Operations |
The Results and Client Value
The Sunwe coal crushing plant has operated flawlessly in the Kuzbass region for 16 months.
It reliably maintains a high-volume, continuous production cycle.
The high-efficiency configuration successfully eliminated over-crushing for the mining group.
By minimizing fines, the system directly increases the market value of the client’s final product.
The client now exports premium-grade bituminous coal with zero sizing complaints.
“Sunwe specialized impact crushers completely transformed our coal processing layout.We eliminated screen clogging and decreased worthless coal dust significantly.Our final product now hits 100% compliance for export markets easily.”— Mr. Alexey Volkov, Mining Operations Director
