1. PYNPUNT GEDREWE OPENING

Staan jou Coke-hanteringsoperasie in die gesig met aanhoudende knelpunte en stygende koste? Die siftingstadium is dikwels 'n kritieke mislukkingspunt, directly impacting downstream process stability and plant profitability. Algemene uitdagings sluit in:

Excessive Fines Carryover: Inefficient separation leads to valuable coke fines contaminating product streams or overloading crushers, degrading final product quality and increasing equipment wear.
Gereelde skermverstopping & Verblinding: Klewerig, moist, or highfines feed material adheres to screen decks, drastically reducing effective screening area and throughput, forcing unscheduled downtime for manual cleaning.
Hoë onderhoud & Komponent Slytasie: The abrasive nature of metallurgical coke accelerates the deterioration of screen panels, dekke, en opwekkers, resulting in high spare parts costs and laborintensive replacement cycles.
Inkonsekwente grootte & Deurset: Inadequate vibration dynamics or screen surface design fail to handle variable feed rates and size distributions, causing offspec product and limiting overall plant capacity.
Excessive Structural Stress & Vibration Transmission: Poorly balanced or isolated equipment transmits damaging forces to support structures and buildings, leading to longterm integrity issues and safety concerns.

How can you achieve consistent product sizing with minimal downtime while controlling the total cost of ownership for your screening assets? The solution requires equipment engineered specifically for the harsh demands of coke classification.

2. PRODUK OORSIG

The Certified Coke Vibration Screen is a heavyduty linear motion screening machine designed for the precise dry sizing and scalping of metallurgical coke in battery, sorteer, and crushing circuits. Its robust construction addresses the unique abrasiveness, digtheid, and operational demands of coke processing.

Operasionele werkvloei:
1. Beheerde voer: Coke feedstock is uniformly distributed across the full width of the screen inlet via an integrated feed box or chute.
2. Doeltreffende stratifikasie & Skeiding: A highGforce linear motion stratifies material rapidly. Particles smaller than the screen panel apertures pass through as undersize, while oversize material conveys along the deck for discharge.
3. Positiewe ontslag: Sized fractions are cleanly discharged from designated discharge spouts into separate chutes or conveyors for downstream processing.

Toepassingsomvang: Primêre grootte (skulpering) van runofoven coke, secondary sizing (gradering) of crushed coke for blast furnace burden, dedusting operations to remove fines (<10mm), and checkscreening in byproduct recovery circuits.

Beperkings: Nie ontwerp vir nat sifting of flodder toedienings nie. Optimal performance requires controlled feed rates within specified capacity limits as per technical specifications.
