1. PYNPUNT GEDREWE OPENING

Is your coke handling operation plagued by inconsistent product quality, oormatige boetes generering, and unplanned maintenance halts? Vir aanlegbestuurders wat toesig hou oor kooksifting, common challenges directly impact profitability and throughput. Ervaar jy:

Verblinding & Oordrag: Moisture or sticky fines blinding screen decks, causing product contamination and forcing premature shutdowns for manual cleaning.
Oormatige stilstand: Frequent bearing failures or structural fatigue on vibrating screens leading to 2040 hours of unscheduled downtime annually for repairs and parts replacement.
Hoë instandhoudingskoste: The abrasive nature of coke accelerating wear on screen panels, dekke, en opwekkers, resulting in high consumable costs and labor for changeouts.
Inefficient Sizing: Inconsistent feed rates or improper vibration dynamics producing offspec material, leading to customer rejections or reprocessing costs.

Die kernvraag is: hoe kan jy presies bereik, reliable coke classification while maximizing equipment uptime and minimizing total cost of ownership? Die antwoord lê in die keuse van 'n doelontwerp Coke Vibrasie Skerm.

2. PRODUK OORSIG

A Coke Vibrasie Skerm is a heavyduty industrial screening machine designed for the dry separation of metallurgical coke into precise size fractions—typically nut coke, briesie, and lump coke—after the quenching process. Its robust construction handles highly abrasive materials while resisting corrosion from residual moisture.

Operasionele werkvloei:
1. Beheerde voer: Quenched coke is conveyed onto the screen’s feed box, distributing material evenly across the full width of the top deck.
2. Hoë-intensiteit skeiding: A dualvibrator mechanism imparts a linear or elliptical motion, stratifying material and propelling particles across the screen cloths.
3. Presiese grootte: Oversize material travels across the top deck apertures, while correctly sized particles pass through to lower decks for further fractionation.
4. Ontslag & Transport: Separated fractions discharge via dedicated chutes onto designated conveyors for stockpiling or direct feed to blast furnaces.

Toepassingsomvang & Beperkings:
Omvang: Ideal for sinter plants, hoogoond laai stelsels, and foundry operations requiring strict size control (bv., 2540mm nut coke). Effective for hot or cold coke screening postquenching.
Beperkings: Nie ontwerp vir nat siftingsprosesse of as 'n plaasvervanger vir scalping skerms wat uiters groot hanteer nie (+300mm) feedstock without prior crushing. Performance is contingent on proper installation on a structurally adequate support base.
