1. PYNPUNT GEDREWE OPENING

Is your coke screening operation a source of constant cost and disruption? Vir aanlegbestuurders en ingenieurskontrakteurs, die uitdagings van die sifting van grootmaat metallurgiese kooks beïnvloed deurset direk, produk kwaliteit, en instandhoudingsbegrotings. Algemene pynpunte sluit in:
Oormatige stilstand: Frequent screen cloth changes due to rapid blinding and abrasion from sharp, hard coke particles halt your entire processing line.
Onbeheerde Boetes Generasie: Inefficient screening creates excessive 5mm fines, degrading product value and creating handling issues for blast furnace operations.
Hoë instandhoudingskoste: The punishing environment leads to premature failure of screen decks, vere, en laers, driving up spare parts inventories and labor hours.
Inkonsekwente produkgradering: Inadequate separation results in offspec material, leading to customer rejections or penalties tied to size distribution guarantees.
Energie ondoeltreffendheid: Poorly designed vibratory systems consume excess power without delivering proportional screening performance.

Are you seeking a robust solution that reduces total cost of ownership while ensuring consistent grade control? The right industrial coke vibration screen is engineered to address these exact operational challenges.

2. PRODUK OORSIG

A heavyduty coke vibration screen is a highcapacity, linear motion screening machine designed for the scalping and precise size classification of hot or cold metallurgical coke. Its primary function is to separate crushed or processed coke into defined fractions (bv., +25mm hoogoond coke, 1025mm neut coke, 10mm briesie) with high efficiency and reliability.

Operasionele werkvloei:
1. Voer & Verspreiding: Bulk coke is fed onto the robust feed box, which evenly distributes material across the full width of the primary screen deck.
2. Grootte skeiding: The dual eccentric shaft vibrator assembly drives the screen box on a linear path. Coke travels over sequentially finer screen cloths (typically wire mesh or polyurethane panels), with undersize material falling through each deck.
3. Ontslag & Versameling: Correctly sized fractions are discharged from separate discharge spouts into designated chutes or conveyors for stockpiling or further processing.

Toepassingsomvang & Beperkings:
Omvang: Ideaal vir sinterplante, hoogoond laai stelsels, and coke handling terminals. Suitable for hot coke screening (with heatresistant components) up to ~200°C and cold screening applications.
Beperkings: Nie ontwerp vir taai materiaal sonder voorbehandeling nie. Maximum feed size is constrained by deck aperture and machine design; typically handles feed up to 150200mm.

Solution Installation of a customdesigned twodeck linear motion coke vibration screen with precisely tuned polyurethane panels on the bottom deck for fines removal.
Results Achieved consistent product grading with less than 3% fines in the nut coke fraction. This contributed directly measured improvements in sinter plant yield.

Merchant Coke Producer – Blast Furnace Coke Line
