1. PYNPUNT GEDREWE OPENING

Is your coke handling operation plagued by persistent bottlenecks and quality control issues? Vir aanlegbestuurders wat toesig hou oor kooksifting, algemene uitdagings het 'n direkte impak op deurset en winsgewendheid. Oormatige besoedeling van boetes in produkstrome kan lei tot klantverwerpings en inkomsteverlies. Gereelde skerm lap verblind van taai, highmoisture coke drastically reduces effective screening area, forcing premature shutdowns for manual cleaning. The constant impact abrasion from bulk coke leads to rapid wear of screen decks and components, generating high replacement part costs and unplanned maintenance windows. Vibration isolation failures transfer destructive forces to support structures, creating longterm integrity concerns and safety risks. How do you maintain specified size fractions consistently while extending equipment service life and maximizing plant uptime? The efficiency of your downstream blast furnace or smelting operation depends on the reliability of this critical separation stage.

2. PRODUK OORSIG

The Coke Vibration Screen is a heavyduty, highamplitude screening machine engineered for the scalping and precise size classification of metallurgical coke, petroleum coke, and foundry coke. Its design prioritizes durability and material throughput in harsh, abrasive environments.

Operasionele werkvloei:
1. Voer & Verspreiding: Bulk coke is fed onto the robust feed box, which evenly distributes the material across the full width of the primary screen deck.
2. HighEnergy Separation: The exciter drive generates a powerful linear or elliptical motion, aggressively conveying coke along the deck while forcing undersized particles through the screen apertures.
3. Fractional Discharge: Korrekte grootte produk (oormaat) discharges from the deck's end, while fines (ondermaat) pass through to a lower collection chute or subsequent deck for further grading.

Toepassingsomvang: Primary sizing of ovendischarged coke, verwydering van briesie (boetes) from blast furnace feed, classification of recirculated coke in sinter plants, en ontstoftoepassings.

Beperkings: Not designed for ultrafine screening (8%) may require predrying or heated deck options.
