1. PYNPUNT GEDREWE OPENING

Is your coke handling operation facing persistent bottlenecks and rising costs? Die siftingstadium is dikwels 'n kritieke mislukkingspunt, directly impacting downstream processing and overall plant profitability. Algemene uitdagings sluit in:

Verblinding & Oordrag: Vog en fyn coke deeltjies blind skerm dekke, terwyl groot materiaal oorgedra word na voltooide produk silo's. Dit lei tot 'n afsonderlike produk, kliënt verwerpings, and costly rehandling.
Oormatige stilstand vir instandhouding: Gereelde laersfoute, skerm lap vervangings, and structural weld cracks demand constant attention from your maintenance crew, stealing valuable production hours.
Hoë energieverbruik & Vibrasie-oordrag: Inefficient vibratory mechanisms consume excess power and transmit destructive forces to the support structure, leading to accelerated wear on the entire screening station.
Inkonsekwente Graadskeiding: An inability to maintain precise cut points leads to product contamination, reducing the market value of your metallurgical or foundry coke.

Are you evaluating how a purposeengineered Coke Vibrasie Skerm can reduce your total cost of ownership, increase screening availability above 95%, and ensure consistent product quality?

2. PRODUK OORSIG

A Coke Vibrasie Skerm is 'n hoë kapasiteit, heavyduty screening machine designed for the scalping, grootte, and dedusting of hot or cold metallurgical coke in battery, blus, and sorting plants. Its core function is to separate coke feedstock into precise size fractions (bv., hoogoond coke, neut coke, briesie) terwyl boetes verwyder word.

Operasionele werkvloei:
1. Bulk coke from the quench car or feed conveyor is discharged onto the screen's robust feed box.
2. Highmagnitude, linear or elliptical vibratory motion stratifies the material bed and propels it across the multideck screening surfaces.
3. Undersize material passes through sequentially smaller apertures on each deck.
4. Correctly sized fractions discharge at designated outlets for conveyor transfer to storage bins or loading stations.
5. Groot materiaal (bv., +80mm) exits at the screen's discharge end for potential crushing or recirculation.

Toepassingsomvang: Primêre en sekondêre grootte van metallurgiese kooks, coke bries herstel, voorafsifting voor vergruising. Not suitable for sticky materials without specialized deck technology or as a replacement for a crusher.
