1. PAINPOINT DRIVEN OPENING

Are your coke screening operations plagued by persistent, costly inefficiencies? Plant managers and procurement specialists face significant challenges in maintaining consistent product quality and throughput. Common pain points include:
Blinding & Downtime: Fine, moist coke particles adhere to screen decks, blinding apertures and forcing frequent, unplanned shutdowns for manual cleaning. This can reduce effective capacity by 1530% and increase labor costs.
Premature Wear & High OPEX: The abrasive nature of metallurgical coke accelerates wear on screen panels and components, leading to frequent replacements, high spare part inventories, and escalating maintenance budgets.
Inconsistent Sizing & Product Rejection: Inefficient stratification and separation result in offspec material—either undersize in the product stream or valuable product lost to fines. This directly impacts sales revenue and customer satisfaction.
Excessive Vibration Transmission: Poorly isolated vibratory motion transmits damaging forces to the support structure, requiring costly reinforcement and creating safety concerns.

The central question is: how can you achieve reliable, highcapacity classification of coke with lower operational costs and maximized equipment lifespan? The answer lies in selecting a vibration screen engineered specifically for this demanding application.

2. PRODUCT OVERVIEW

The ISO Certified Coke Vibration Screen is a heavyduty linear or elliptical motion vibrating screen designed for the precise sizing and scalping of metallurgical coke (met coke) and petroleum coke (pet coke). Its core function is to separate fed material into two or more specific size fractions with high efficiency and reliability.

Operational Workflow:
1. Controlled Feed: Coke from a crusher or feed bin is evenly distributed across the full width of the screen’s inlet via an apron feeder or chute.
2. Stratification & Separation: HighGforce vibratory motion stratifies the material bed, allowing finer particles to sift through precisely sized screen panel apertures.
3. Efficient Discharge: Correctly sized oversize material travels along the deck to a discharge spout, while undersize material passes through to a separate collection hopper.
4. Continuous Operation: Engineered antiblinding systems and robust construction allow for continuous 24/7 operation with minimal intervention.

Application Scope: Primary sizing (scalping) and secondary sizing (classification) of metallurgical coke for blast furnaces, foundries, and smelters; dedusting of petroleum coke; recovery of breeze.

Key Limitations: Not designed for wet screening applications unless specified with spray bars; maximum feed size is limited by the design of the feed box and initial impact deck.
