1. PAINPOINT DRIVEN OPENING

Is your coke processing operation struggling with persistent bottlenecks and escalating costs at the screening stage? Common challenges with conventional screens directly impact your bottom line. Are you experiencing:
Blinding & Downtime: Moisture and fine coke particles clog screen decks, requiring frequent shutdowns for manual cleaning, costing hundreds of production hours annually.
Inconsistent Grading: Poor separation leads to offspec product (undersize in metallurgical coke, oversize in breeze), resulting in product rejection and revenue loss.
Excessive Maintenance: The abrasive nature of coke accelerates wear on screen panels and components, driving up spare parts costs and labor for replacements.
High Energy Consumption: Inefficient vibration mechanisms and heavyduty designs lead to disproportionately high power usage per ton of material processed.
Structural Fatigue: Constant, highimpact loads from bulk coke can cause weld cracks and structural failures in the screen body, risking major unplanned downtime.

The central question for plant managers is clear: how can you achieve reliable, continuous coke classification with lower operational expenditure and maximized equipment lifespan?

2. PRODUCT OVERVIEW

The China Coke Vibration Screen is a heavyduty, linear motion vibrating screen engineered specifically for the highvolume sizing and scalping of metallurgical coke, petroleum coke, and foundry coke. It is designed to handle the unique abrasiveness, density, and size ranges of bulk coke in processing plants.

Operational Workflow:
1. Feed & Distribution: Bulk coke from crushers or ovens is fed onto the screen’s robust feed box, which evenly distributes material across the full width of the screening surface.
2. Efficient Stratification & Separation: Dual vibrator motors generate a linear throwing motion, stratifying material rapidly. Coke particles smaller than the screen panel apertures pass through as undersize product.
3. Discharge: Correctly sized oversize material travels along the deck length and discharges at the end, while undersize material collects in a hopper below.

Application Scope: Primary sizing (scalping) of runofoven coke, secondary screening of crushed coke (e.g., 2540mm blast furnace coke), dedusting (coke breeze removal), and dewatering applications.

Limitations: Not designed for extremely sticky materials without specialized deck treatments. Maximum lump size is typically limited to 200mm; alternative solutions are required for larger primary runofmine scalping.

Modular Polyurethane Screen Panels | Technical Basis: High abrasionresistant elastomer with openarea optimization | Operational Benefit: Panel life is 35x longer than steel wire mesh, significantly reducing changeout frequency and downtime. Antiblinding properties maintain consistent throughput. | ROI Impact: Direct reduction in consumables cost by up to 60% and labor savings from fewer maintenance interventions.
Dual CounterRotating Vibrator Motors | Technical Basis: Synchronized motors producing a linear force for uniform material conveyance | Operational Benefit: Provides stable, adjustable amplitude for optimal stratification without excessive hop or deck impact. Simple lubrication points reduce servicing time. | ROI Impact: Consistent screening efficiency ensures onspec product yield; energyefficient motor design lowers kW consumption per ton screened.
Reinforced BoxSection Side Plates | Technical Basis: Highstrength steel construction with internal ribbing and stressrelieved welds | Operational Benefit: Withstands dynamic loads from bulk coke without flexing or fatigue cracking, ensuring longterm structural integrity. | ROI Impact: Eliminates costly midlife frame repairs or premature equipment replacement, protecting capital investment.
Rubber Shear Mount Isolation System | Technical Basis: Multilayered rubber buffers between screen body and support structure | Operational Benefit: Absorbs up to 85% of dynamic vibrations transmitted to the supporting substructure. This minimizes foundation stress and reduces ambient noise levels. | ROI Impact: Lowers installation complexity/cost by reducing need for massive foundations; extends lifespan of surrounding infrastructure.
Centralized Greasing Lube Points | Technical Basis: Manifold system routing grease directly to all vibrator bearing points from one location | Operational Benefit: Enables safe, rapid lubrication during scheduled maintenance pauses without dismantling guards or accessing dangerous moving parts. | Operational Benefit Ensures bearing longevity through consistent lubrication compliance.
