1. PAINPOINT DRIVEN OPENING

Is your coke screening operation plagued by persistent bottlenecks that erode profitability? For plant managers and engineering contractors, the challenges of screening metallurgical coke are acute. Excessive fines generation due to aggressive vibration directly impacts blast furnace efficiency and product revenue. Frequent screen cloth changes, driven by premature wear from abrasive coke, cause significant production downtime and high consumable costs. Inconsistent particle size distribution, resulting from inefficient separation or blinding, compromises downstream process stability. Moreover, structural failures in the screen body or deck from highcycle fatigue lead to catastrophic unplanned shutdowns. Are you facing rising maintenance costs, unpredictable availability, and a constant battle to meet stringent size specifications? The core of these issues often lies in the design and durability of your coke vibration screen.

2. PRODUCT OVERVIEW

This product is a heavyduty linear motion vibrating screen engineered explicitly for the sizing and scalping of metallurgical coke. Its design prioritizes durability, precise separation, and highcapacity throughput in demanding coke handling plants.

Operational Workflow:
1. Feed & Distribution: Coke feedstock is evenly distributed across the full width of the screen inlet via an integrated feed box.
2. Stratified Separation: Two counterrotating vibratory motors generate a linear throwing motion, stratifying material across multiple deck levels equipped with defined aperture screen panels.
3. Size Classification: Oversize material travels across the top deck for discharge; middlings are separated on subsequent decks; correctly sized product passes through the apertures.
4. Discharge: Separated fractions are discharged via dedicated chutes for routing to blast furnace bins, crusher circuits, or product stockpiles.

Application Scope: Primary sizing of ovendischarged coke, coke breeze removal, prescreening before crushing, and final product grading.
Limitations: Not designed for wet screening applications or for materials with extreme temperature fluctuations beyond specified ranges.

3. CORE FEATURES

Modular Deck System | Technical Basis: Boltin, sidetensioned panel frames with independent clamping. | Operational Benefit: Enables singledeck changeouts in under two hours versus full deck replacement; allows use of varied panel materials (rubber, polyurethane, woven wire) per deck level based on wear profile. | ROI Impact: Reduces downtime for screen media maintenance by up to 60% and lowers consumable costs by targeting material grade where needed.

Dual CounterRotating Motor Drive | Technical Basis: Two synchronized vibratory motors generating a linear force vector; nonsynchronous operation causes immediate selfcancellation of vibration. | Operational Benefit: Provides consistent material travel speed and throw pattern for reliable sizing; inherent safety feature prevents structural damage if one motor fails. | ROI Impact: Ensures stable product quality (size consistency >98%) and eliminates risk of catastrophic drive failure leading to extended downtime.

HuckBolted Construction & Reinforced Deck Frames | Technical Basis: Highstrength alloy steel side plates joined via Huck fastening system; internal cross members are fully welded to side plates before stressrelieving. | Operational Benefit: Creates a rigid, monolithic frame resistant to cracking from cyclic stress; dramatically extends service life in 24/7 operation. | ROI Impact: Field data shows a >40% improvement in structural lifespan compared to traditional bolted frames, deferring major capital expenditure.

DustEncapsulated Vibrator Motors | Technical Basis: IP66rated protection with labyrinth seals and positivepressure dust purge ports (optional). | Operational Benefit: Protects motor bearings from pervasive coke dust ingress, the leading cause of bearing seizure and motor failure. | ROI Impact: Extends motor service life by an average of 30%, reducing spare parts inventory and replacement labor costs.

Adjustable Vibration Amplitude | Technical Basis: External weight adjustment on motor shafts without disassembly.| Operational Benefit: Operators can finetune the throw amplitude to match specific feed rates or coke characteristics (e.g., sticky vs. freeflowing), optimizing efficiency.| ROI Impact: Maximizes screening efficiency across varying feed conditions, preventing lost capacity or misdirected product that impacts furnace performance.
