1. PYNPUNT GEDREWE OPENING

Is your coke handling operation compromised by inefficient screening? Common challenges with standard vibratory screens directly impact your bottom line and plant reliability.

Excessive Downtime for Screen Deck Changes: Frequent blinding and wear of screen cloths halt your entire sorting line. Each changeover can cost hours of lost production and significant labor expense.
Inkonsekwente produkgradering & Fines Contamination: Inadequate vibration control or poor deck design leads to offspec coke product. This results in rejected loads, customer penalties, and reduced product value.
Hoë instandhoudingskoste & Component Fatigue: Harsh, abrasive coke particles rapidly degrade underengineered screen boxes, dekke, en vibratormeganismes, leading to unplanned repairs and parts replacement.
Structural Integrity Concerns Under Load: Continuous hightonnage processing can induce stress cracks in welded frames or failures in isolation systems, creating safety risks and major capital repairs.

Are you seeking a screening solution that delivers consistent uptime, protects product quality, en verminder jou totale koste van eienaarskap? The right industrialgrade Coke Vibrasie Skerm is engineered to address these exact operational challenges.

2. PRODUK OORSIG

A Coke Vibrasie Skerm is a heavyduty industrial screening machine designed for the highvolume sizing and scalping of metallurgical coke and similar abrasive materials in bulk handling plants. Its core function is to separate coke into precise size fractions (bv., hoogoond coke, neut coke) terwyl boetes en kontaminante verwyder word.

Operasionele werkvloei:
1. Voer & Verspreiding: Raw or processed coke is fed onto the screen’s robust feed box, wat materiaal eweredig oor die volle breedte van die boonste dek versprei.
2. Stratifikasie & Skeiding: Hoë intensiteit, lineêre of elliptiese vibrasie stratifiseer die materiaalbed. Smaller particles pass through apertures in the screen media (draad lap, poliuretaan panele), terwyl groter deeltjies oor die dekoppervlak beweeg.
3. Ontslag & Transport: Correctly sized fractions are discharged via separate chutes onto designated conveyors or into storage bins for downstream processing or shipment.

Toepassingsomvang: Primary sizing of ovendischarged coke, secondary screening for blast furnace feed, recirculating load separation in crushing circuits.
Beperkings: Not designed for sticky or highly moist materials without pretreatment; maximum capacity is governed by particle size distribution and deck configuration.
