1. PYNPUNT GEDREWE OPENING

Is your coke processing operation struggling with persistent bottlenecks and escalating costs at the screening stage? Algemene uitdagings met konvensionele skerms het 'n direkte impak op jou winspunt. Ervaar jy:
Verblinding & Stilstand: Vog en fyn coke-deeltjies verstop skermdekke, vereis gereelde stilstand vir handskoonmaak, honderde produksie-ure jaarliks ​​kos.
Inconsistent Grading: Poor separation leads to offspec product (undersize in metallurgical coke, oversize in breeze), resulting in product rejection and revenue loss.
Excessive Maintenance: The abrasive nature of coke accelerates wear on screen panels and components, driving up spare parts costs and labor for replacements.
Hoë energieverbruik: Inefficient vibration mechanisms and heavyduty designs lead to disproportionately high power usage per ton of material processed.
Strukturele moegheid: Konstant, highimpact loads from bulk coke can cause weld cracks and structural failures in the screen body, risking major unplanned downtime.

Die sentrale vraag vir aanlegbestuurders is duidelik: hoe kan jy betroubare bereik, continuous coke classification with lower operational expenditure and maximized equipment lifespan?

2. PRODUK OORSIG

Die China Coke Vibration Screen is 'n swaardiens, linear motion vibrating screen engineered specifically for the highvolume sizing and scalping of metallurgical coke, petroleum coke, en gietery coke. It is designed to handle the unique abrasiveness, digtheid, and size ranges of bulk coke in processing plants.

Operasionele werkvloei:
1. Voer & Verspreiding: Bulk coke from crushers or ovens is fed onto the screen’s robust feed box, which evenly distributes material across the full width of the screening surface.
2. Doeltreffende stratifikasie & Skeiding: Dual vibrator motors generate a linear throwing motion, stratifying material rapidly. Coke particles smaller than the screen panel apertures pass through as undersize product.
3. Ontslag: Correctly sized oversize material travels along the deck length and discharges at the end, while undersize material collects in a hopper below.

Toepassingsomvang: Primêre grootte (skulpering) van runofoven coke, secondary screening of crushed coke (bv., 2540mm blast furnace coke), ontstof (coke breeze removal), and dewatering applications.

Beperkings: Not designed for extremely sticky materials without specialized deck treatments. Maximum lump size is typically limited to 200mm; alternative solutions are required for larger primary runofmine scalping.

6. TOEPASSINGSSCENARIO'S

Metallurgical Coke Plant – Blast Furnace Feed Preparation

Challenge A major steel plant faced frequent blinding on traditional screens during humid months, causing a ~20% drop in throughput for their critical +25mm BF coke fraction and generating excessive 10mm fines.
Solution Installation of twotier China Coke Vibration Screens equipped with nonblinding polyurethane panels featuring tapered apertures.
Results Screening efficiency stabilized at ≥94%. Annual production of onspec (+25mm) coke increased by an estimated 75,000 ton. Maintenance downtime for screen cleaning was reduced by over 400 hours per year.

Petroleum Coke Calcining Plant – Green Coke Scalping

Challenge A calciner needed reliable precalcination scalping of green petroleum coke at high temperatures (~150°C feed) to remove sub2” fractions before kiln entry. Existing screens suffered rapid thermal warping and bearing failures.
Solution Deployment of hightemperature adapted China Coke Vibration Screens featuring heatresistant seals on bearings and thermally stable deck components.
Results The solution provided continuous operation at elevated temperatures without performance degradation. Bearing service life extended from under six months to over two years between changes.
