1. PAINPOINT DRIVEN OPENING

Are escalating operational costs and unpredictable downtime eroding your mineral processing margins? In coke handling and classification, inefficient screening directly impacts product quality, throughput, and maintenance budgets. Common challenges include:
Blinding & Carryover: Moisture and fines clog screen decks, reducing effective screening area and causing product contamination. This leads to rejected loads, customer chargebacks, and manual cleaning downtime.
Excessive Wear & Maintenance: The abrasive nature of coke rapidly degrades standard screen panels and components, resulting in frequent replacements, high spare parts inventories, and lost production hours.
Inconsistent Particle Size Distribution: Unstable vibration or inadequate screening action produces offspec material, compromising downstream blast furnace efficiency or foundry coke specifications.
High Energy Consumption & Structural Stress: Poorly balanced vibratory systems consume excess power and transmit damaging forces to the support structure, increasing both operational costs and longterm facility wear.

Is your current solution addressing these core issues? A precisionengineered Luxury Coke Vibration Screen is not merely a component; it is a strategic investment in process stability and cost control.

2. PRODUCT OVERVIEW

The Luxury Coke Vibration Screen is a highcapacity, heavyduty linear motion vibrating screen specifically engineered for the dry screening of metallurgical coke and similar abrasive materials. Its design focuses on maximizing availability and minimizing total cost of ownership in continuous 24/7 operations.

Operational Workflow:
1. Controlled Feed: Sized coke from crushers or storage is evenly distributed across the full width of the feed inlet.
2. Efficient Stratification & Separation: A highGforce linear vibration stratifies the material bed, forcing fines downward while conveying oversize along the deck for accurate separation through precisely sized screen apertures.
3. Discharge: Correctly sized fractions are discharged into distinct chutes—oversize for recirculation, onspec product for shipment or further processing.

Application Scope: Ideal for final sizing (e.g., separating 2580mm blast furnace coke from fines) or scalpandgrade operations in coke plants, steel mills, and foundries.
Limitations: Not designed for wet screening applications or for materials with extreme stickiness without specialized deck treatments.
