- Core Purification & Protection: Essential Defense for Coal Streams
- Critical Function:Removal of damaging ferrous contaminants (scrap metal, bolts, tool fragments) from coal streams – ensuring product purity and preventing catastrophic equipment damage.
- Impact:
- Equipment Longevity:Shields crushers, pulverizers, conveyor belts, and screens from costly impacts, jams, and wear caused by tramp metal.
- Product Integrity:Delivers cleaner coal meeting stringent quality specifications for power generation, metallurgy, and industrial use.
- Operational Continuity:Minimizes unplanned downtime and expensive repair costs associated with metal-induced breakdowns.
- Strategic Deployment: Optimizing Removal at Critical Points
- Targeted Installation:Equipment is strategically integrated into coal flow paths for maximum effectiveness:
- Conveyor Systems:Mounted at head pulleys, mid-points, or above vibrating feeders/chutes for continuous, automated metal capture.
- Enclosed Pipelines:Pipe-type magnetic separators (e.g., RCYA Series) installed via flanges directly within transfer pipelines where conveyors aren’t present.
- High-Risk Zones:Explosion-proof electromagnetic separators (e.g., RBCDD Series) deployed in hazardous underground mining areas or processing plants with combustible dust/gas atmospheres.
III. Engineered for Coal Industry Demands: Key Equipment Advantages
Hengji offers a comprehensive portfolio designed for coal’s specific challenges:
- High-Efficiency Separation:
- Permanent Magnet Units:Provide powerful, zero-energy capture of ferrous contaminants.
- Electromagnetic Separators (e.g., RCDB, RBCDD Series):Feature deep magnetic fields, robust sealed construction (dust/water resistant), and strong lifting force for demanding conditions. Self-cooling ensures reliability.
- Unmatched Adaptability:
- Handles all coal forms: run-of-mine (ROM), crushed, sized, pulverized, or slurry.
- Performs reliably in dusty, humid, and high-volume environments typical of coal operations.
- Enhanced Automation & Safety:
- Self-Cleaning Models (e.g., RCDD Series):Automatically discharge captured metal, minimizing manual handling and labor requirements.
- Explosion-Proof Certification:RBCDD Series units meet stringent safety standards (Ex d I Mb) for intrinsically safe operation in potentially explosive atmospheres.
- Specialized Solutions:
- Plate Magnets:Ideal for chutes, hoppers, and gravity-fed systems to remove fine tramp iron.
- Disc Separators (e.g., for Coal Prep Plants):Effectively remove iron from non-magnetic coal streams in washing and beneficiation circuits.
- Tangible Industry Value: Driving Operational Excellence
Implementing Hengji iron removal technology delivers measurable benefits:
- Enhanced Safety:Significantly reduces risks of sparks from metal impact, catastrophic belt tears, and equipment failures leading to accidents. Vital for personnel protection.
- Superior Product Quality:Consistently delivers coal with lower ash content and minimized ferrous contamination, meeting premium market specifications and reducing slagging in boilers.
- Reduced Operating Costs:
- Dramatically lowers expenditure on crusher mantles, screen panels, conveyor belts, and pulverizer components.
- Minimizes costly production stoppages for repairs.
- Decreases manual labor needed for metal removal and cleanup.
- Maximized Productivity:Ensures smooth, uninterrupted coal flow through the processing chain, maximizing plant throughput and revenue.
- Compliance & Risk Mitigation:Explosion-proof models ensure adherence to strict safety regulations in hazardous zones, mitigating explosion risks.
