1. PYNPUNT GEDREWE OPENING

Is jou coke siftingsoperasie geteister deur aanhoudende, duur ondoeltreffendheid? For plant managers and engineering contractors in the metallurgical coke and foundry coke sectors, the vibration screen is a critical yet problematic node. Algemene uitdagings sluit in:

Verblinding & Oordrag: Moisture and fine coke dust adhere to screen decks, blinding apertures and forcing undersized material to carry over. This reduces screening efficiency by 1530%, contaminates product grades, and directly impacts blast furnace burden consistency.
Oormatige stilstand vir instandhouding: Traditional screens require frequent shutdowns for deck cleaning, tensioning, or panel replacement. Unplanned downtime for a primary coke screen can cost over $5,000 per uur in verlore produksie.
Strukturele moegheid & Premature Failure: The abrasive nature of coke and the highcycle operation induce metal fatigue in side plates, cross members, and welds. This leads to catastrophic frame cracks, often within 1218 maande diens, necessitating a full rebuild or replacement.
Hoë energieverbruik & Geraas: Inefficient drive systems and unbalanced mass designs consume excess power—a significant operational cost—while generating noise levels that exceed 90 dB(A), creating environmental and worker safety concerns.

Are you seeking a vibration screen solution that delivers consistent product sizing with minimal downtime, engineered specifically for the harsh demands of coke classification?

2. PRODUK OORSIG

The China Coke Vibration Screen is a heavyduty, linear motion vibrating screen designed for the highcapacity sizing and scalping of metallurgical (hoogoond) coke and foundry coke. Engineered for robustness in highabrasion, highdutycycle environments, it ensures reliable separation of coke breeze from lump coke.

Operasionele werkvloei:
1. Voer & Verspreiding: Sized coke from the crusher or oven is fed onto the screen via a regulated feed chute onto a robust feed deck for even material distribution.
2. Stratifikasie & Skeiding: The dualshaft vibrator assembly generates a linear throwing motion, stratifiserende materiaal. Oormaat (klont coke) travels across the deck surface to the discharge end, terwyl dit ondermaat is (coke bries) passes through the defined screen apertures.
3. Produk Hantering: Separated fractions are discharged via dedicated chutes—lump coke to blast furnace stockhouses or loading bays, and coke breeze to sintering plants or storage.

Toepassingsomvang: Primêre grootte (bv., separating >25mm from <25mm), scalpings of oven charge, dedusting of crushed coke. Not recommended for extremely sticky materials without specialized deck systems or for wet screening applications without design modifications.
