1. PYNPUNT GEDREWE OPENING

Is your coke screening operation plagued by persistent, duur ondoeltreffendheid? Vir aanlegbestuurders en ingenieurskontrakteurs, the challenges of screening bulk metallurgical coke directly impact throughput, produk kwaliteit, and bottomline profitability. Algemene operasionele hekkies sluit in:

Verblinding & Oordrag: Fine coke breeze and moisture cause screen mesh blinding, vermindering van effektiewe siftingsarea. Terselfdertyd, undersize material carries over with the product stream, contaminating blast furnace feed and degrading its performance.
Oormatige instandhoudingstyd: The abrasive nature of coke accelerates wear on screen decks, syplate, and exciters. Frequent component replacement leads to unplanned downtime and high spare parts inventories.
Ondoeltreffende Boetesskeiding: Inadequate separation of the 010mm fraction results in lost revenue from breeze sales and inefficient recycling within the coke plant.
Strukturele moegheid & Failure: High Gforces from traditional vibrators transfer damaging stress to the screen body and support structure, leading to weld cracks and catastrophic frame failures.
Hoë energieverbruik: Inefficient drive systems and oversized motors run continuously, contributing to significant, nonproductive power costs.

Are you seeking a solution that reduces downtime by 30% or more while ensuring consistent product sizing? The answer lies in selecting a coke vibration screen engineered specifically to overcome these materialspecific challenges.

2. PRODUK OORSIG

The equipment in focus is a heavyduty Coke Classification Vibrating Screen, designed for highcapacity sizing of hot or cold metallurgical coke (25mm 80mm) from oven discharge and the subsequent separation of coke breeze (0mm 10mm).

Operasionele werkvloei:
1. Voer & Verspreiding: Bulk coke is uniformly fed onto the robust feed box, which distributes the material across the full width of the primary screen deck.
2. Primêre grootte: A highstrength wire mesh or punch plate deck performs the primary separation, allowing undersize material (breeze and small fractions) to pass through.
3. Sekondêre sifting & Boetes Verwydering: A second deck further refines the separation, ensuring maximum recovery of marketable coke breeze.
4. Ontslag: Correctly sized foundry or blast furnace coke discharges from the screen end, while separated fines are collected via a dedicated chute for processing or sale.

Toepassingsomvang & Beperkings:
This equipment is designed for dry or slightly moist coke screening in fixed plant installations. It is not suitable as a replacement for rotary breakers or for handling highly sticky materials without pretreatment. Maximum lump size should not exceed 150% of the nominal top deck aperture.

6. TOEPASSINGSSCENARIO'S

Integrated Steel Plant Coke Oven Battery Discharge

Uitdaging: A major steel producer faced severe blinding on their existing screens due to residual moisture in quenched coke. This caused frequent overloads on downstream crushers and inconsistent blast furnace feed sizing (+/15mm afwyking).
Oplossing: Implementation of two parallel heavyduty linear motion Coke Vibration Screens featuring nonblinding balltray decks on the fines removal section.
Resultate: Screening efficiency stabilized at ≥94%. Oversize contamination was eliminated (<1%), protecting crusher integrity. The consistent product sizing contributed to a documented ~3% improvement in blast furnace burden permeability.

Merchant Coke Producer – Breeze Recovery

Uitdaging: A merchant plant was losing significant revenue due to poor fines capture; an estimated 810% of saleable breeze was being incorrectly routed back into crusher feed circuits as "circulating load."
Oplossing: Retrofitting a dedicated Coke Vibration Screen with a finemesh secondary deck into their product classification circuit postcrushing.
Resultate: Breeze recovery increased from ~82% to over 95%, creating an additional revenue stream exceeding project payback within one year based on market prices for fuelgrade fines.
