1. PYNPUNT GEDREWE OPENING

Is your coke screening operation plagued by persistent bottlenecks that erode profitability? Vir aanlegbestuurders en ingenieurskontrakteurs, 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. Inkonsekwente deeltjiegrootteverspreiding, resulting from inefficient separation or blinding, compromises downstream process stability. Bowendien, structural failures in the screen body or deck from highcycle fatigue lead to catastrophic unplanned shutdowns. Are you facing rising maintenance costs, onvoorspelbare beskikbaarheid, and a constant battle to meet stringent size specifications? The core of these issues often lies in the design and durability of your coke vibrasie skerm.

2. PRODUK OORSIG

This product is a heavyduty linear motion vibrating screen engineered explicitly for the sizing and scalping of metallurgical coke. Die ontwerp gee prioriteit aan duursaamheid, precise separation, and highcapacity throughput in demanding coke handling plants.

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

Toepassingsomvang: Primary sizing of ovendischarged coke, coke breeze removal, voorafsifting voor vergruising, and final product grading.
Beperkings: Not designed for wet screening applications or for materials with extreme temperature fluctuations beyond specified ranges.

3. KERNKENMERKE

Modulêre dekstelsel | Tegniese basis: Die balle, sidetensioned panel frames with independent clamping. | Bedryfsvoordeel: Enables singledeck changeouts in under two hours versus full deck replacement; allows use of varied panel materials (rubber, poliuretaan, geweefde draad) per deck level based on wear profile. | ROI impak: Reduces downtime for screen media maintenance by up to 60% and lowers consumable costs by targeting material grade where needed.

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

HuckBolt-konstruksie & Reinforced Deck Frames | Tegniese basis: Highstrength alloy steel side plates joined via Huck fastening system; internal cross members are fully welded to side plates before stressrelieving. | Bedryfsvoordeel: Skep 'n rigiede, monolithic frame resistant to cracking from cyclic stress; dramatically extends service life in 24/7 operasie. | ROI impak: Velddata toon a >40% improvement in structural lifespan compared to traditional bolted frames, deferring major capital expenditure.

DustEncapsulated Vibrator Motors | Tegniese basis: IP66rated protection with labyrinth seals and positivepressure dust purge ports (opsioneel). | Bedryfsvoordeel: Protects motor bearings from pervasive coke dust ingress, the leading cause of bearing seizure and motor failure. | ROI impak: Extends motor service life by an average of 30%, vermindering van onderdelevoorraad en vervangingsarbeidskoste.

Adjustable Vibration Amplitude | Tegniese basis: External weight adjustment on motor shafts without disassembly.| Bedryfsvoordeel: Operators can finetune the throw amplitude to match specific feed rates or coke characteristics (bv., sticky vs. freeflowing), doeltreffendheid te optimaliseer.| ROI impak: Maximizes screening efficiency across varying feed conditions, preventing lost capacity or misdirected product that impacts furnace performance.
