Mobile Coal Crushing and Screening Equipment
Addressing the specific needs of coal mining operations, coal yard storage, and coal preparation plants requiring temporary production boosts, Baichy has introduced a mobile coal crushing and screening station that achieves an integrated, closed-loop workflow encompassing "feeding + crushing + screening + conveying." This equipment can be deployed directly to raw coal production sites or coal storage yards; through precision screening and high-efficiency crushing, it rapidly transforms raw coal into clean coal that meets the specific standards required by power plants, steel mills, or residential consumers. The unit offers flexible capacity configurations ranging from 50 to 300 tons per hour (tph).
1. Typical Coal Processing Configuration (YDPZ Series)
| Configuration Aspect | Technical Parameters/Components | Key Advantages |
| Core Crusher | Heavy-duty Impact Crusher / Double-toothed Roll Crusher | Specifically designed for the medium-to-soft hardness of coal; ensures a low rate of "over-crushing" to preserve the coal's calorific value. |
| Screening System | 3-layer / 4-layer High-frequency Vibrating Screen | Enables precise, multi-stage particle size classification (e.g., 0–10 mm, 10–25 mm, 25–50 mm). |
| Mobility | Tire-Mounted Heavy-duty Chassis | Ready to move via towing; requires no fixed foundation; site relocation takes only 2 hours. |
| Control System | Intelligent PLC Control Cabinet | Supports one-touch start/stop operations and automatic overload protection, thereby minimizing the need for manual intervention. |
| Environmental Controls | Water Spray Dust Suppression + Enclosed Conveyor Belts | Effectively suppresses airborne coal dust and ensures compliance with environmental regulatory acceptance standards. |
2. Why Are Coal Processors Shifting to "Mobile" Solutions?

1. Eliminating Costly "Short-Haul Transport" Expenses
Traditional fixed-plant production lines require transporting coal from storage piles to a centralized crushing facility, incurring substantial loading and transportation costs.
Direct On-Site Crushing: Mobile stations can be driven directly to the coal piles to commence operations; the finished coal is loaded directly onto trucks at the site, thereby drastically streamlining the logistics chain.
2. Precise Particle Size Control: Avoiding "Over-Crushing"
In the coal market, the selling price of lump coal is typically higher than that of fine coal (coal dust). Optimized Crushing Chamber: Our impact crusher and toothed roll crusher designs are engineered to maximize the crushing ratio while simultaneously minimizing the generation of coal fines. This increases the yield of lump coal, thereby directly boosting your profit per ton.
3. Flexible Adaptability to Varying Coal Compositions
Whether processing raw coal, middlings, or coal gangue, the modular design of our mobile station demonstrates distinct advantages.
Multifunctional Screening: The unit allows for pre-crushing screening; coal that already meets size specifications can be directly discharged, ensuring that only oversized materials enter the crusher. This conserves energy, reduces consumption, and significantly boosts the machine's overall throughput.
4. Addressing the Pain Points of "Environmental Approvals" and "Construction Timelines"
Fixed production lines typically entail lengthy construction periods and involve complex infrastructure approval processes.
Ready-to-Deploy Mobility: Our mobile station requires no concrete foundation, allowing for rapid installation and commissioning. Furthermore, its integrated dust suppression system ensures that operations within coal yards remain free from dust-related complaints.
3. Frequently Asked Questions (FAQ)
Q: Can this equipment process hard raw coal that contains coal gangue?
A: Yes, it can. We recommend selecting an impact crusher equipped with high-manganese steel blow bars. This configuration is effective not only for processing soft bituminous coal but also delivers excellent crushing performance on harder coal gangue, ensuring a superior final product shape.
Q: Will high coal moisture levels (particularly during the rainy season) cause the screening machine to clog?
A: To address high-moisture coal, we offer optional upgrades such as high-angle high-frequency screens or self-cleaning mechanisms. Additionally, we optimize conveyor angles to prevent material from adhering to the hopper walls or clogging at the discharge points.
Q: How many personnel are required to operate this equipment?
A: The entire unit features a high degree of automation. It requires only one loader operator to assist with feeding materials and one additional person to monitor the control console, thereby significantly reducing labor costs.
