Teiken aanlegbestuurders, Verkrygingspesialiste & Ingenieurskontrakteurs: Optimize Your Coke Sizing & Classification with Advanced Vibration Screen Technology

1. Addressing Critical Operational Challenges in Coke Handling

Is your coke screening process a source of inefficiency and unexpected cost? For operations dependent on consistent coke quality for blast furnace feed, foundry operations, or anode production, subpar screening directly impacts downstream performance and profitability. Algemene pynpunte sluit in:
Oormatige boetes Generasie & Produk Degradasie: Conventional screens with highimpact loading can fracture coke, increasing the percentage of undersize material (10mm/6mm) and reducing the yield of valuable lump product. This represents direct revenue loss.
Frequent Downtime for Screen Cloth Changes: Blinding and pegging of screen meshes by moist or sticky coke halts production. Industry data indicates average downtime for screen maintenance can exceed 15 hours per month per line.
Hoë energieverbruik & Strukturele moegheid: Inefficient vibratory motion requires more power to move material, while excessive vibration transmission to support structures leads to premature wear and potential foundation issues.
Inkonsekwente grootte & Besoedeling: Inaccurate separation results in oversized fines entering the lump stream or valuable lump coke being lost to the fines conveyor, compromising product specifications and customer contracts.
Harsh Environmental Working Conditions: Dust emission at transfer points and high noise levels create noncompliance risks and operator health concerns.

Are you evaluating solutions to reduce total cost of ownership, verleng gemiddelde tyd tussen mislukkings (MTBF), and protect your premium coke product integrity?

2. Produk Oorsig: HeavyDuty EcoFriendly Coke Vibration Screens

Our engineered line of EcoFriendly Coke Vibration Screens is designed for highcapacity sizing (skulpering, gradering) of metallurgical (ontmoet) coke, petroleum coke (petcoke), and foundry coke. These screens prioritize material preservation while maximizing throughput and operational cleanliness.

Operasionele werkvloei:
1. Beheerde voer: Coke is fed onto the screen via a controlledrate feeder, minimizing impact load on the screen cloth.
2. Doeltreffende stratifikasie & Skeiding: A combination of precise vibratory motion and optimized deck layout stratifies material, allowing accurately sized particles to pass through the screen media.
3. Clean Discharge: Sized fractions (bv., knop, moer, briesie) are discharged into separate chutes with minimal intermixing for downstream processing or loading.

Toepassingsomvang: Primary and secondary screening of dry or slightly moist coke in battery discharge stations, crushing plant circuits, and loadout facilities. Ideal apertures from 4mm to 80mm.

Beperkings: Not designed as a dewatering screen for slurry applications or for handling highly adhesive materials without specialized screen media.
