1. PAINPOINT DRIVEN OPENING

Is your coke handling operation plagued by inefficient screening, excessive product degradation, and unplanned maintenance costs? For plant managers and engineering contractors, a suboptimal coke vibration screen directly impacts profitability through several critical challenges:

Product Loss and Contamination: Inconsistent particle separation leads to onspec coke being misdirected to fines or oversized fractions, resulting in revenue loss and product quality complaints.
Excessive Downtime for Maintenance: Frequent failures of screen decks, bearings, or vibration mechanisms halt entire processing lines, costing thousands per hour in lost production.
High Operational Costs: Inefficient screening requires higher energy consumption per ton processed. Premature wear of components due to poor design or material choice drives up spare parts inventory and labor expenses.
Dust Emission and Safety Hazards: Poorly sealed or overly aggressive vibrating screens can generate significant dust, creating environmental compliance issues and unsafe working conditions.

Are you evaluating equipment that can deliver precise grading with higher availability and a lower total cost of ownership? The solution lies in specifying a coke vibration screen engineered for the specific abrasiveness and density of metallurgical or fuel coke.

2. PRODUCT OVERVIEW

A coke vibration screen is a heavyduty industrial separator designed for the dry screening of crushed coke into precise size fractions. Its core function is to ensure consistent product quality for blast furnace charging, foundry operations, or other industrial uses by efficiently removing fines and oversize material.

Operational Workflow:
1. Feed Introduction: Crushed coke is uniformly fed onto the inclined screen deck(s) via a chute or conveyor.
2. Vibratory Separation: Highintensity, linear or circular vibratory motion stratifies the material. Smaller particles pass through the deck apertures (undersize), while larger particles travel across the deck surface (oversize).
3. Fraction Discharge: Separated streams—typically oversize, product grade(s), and fines—are discharged via distinct outlets for further processing or shipment.

Application Scope & Limitations:
This equipment is designed for dry screening of bulk coke. It is not suitable for wet screening applications or for materials with high moisture content that cause blinding (clogging of screen openings). Optimal performance requires controlled feed rates and consistent feed size distribution as per design parameters.

6. APPLICATION SCENARIOS

[Steel Plant Blast Furnace Feed] Challenge: A major integrated steel mill experienced inconsistent blast furnace performance due to variability in coke size (2575mm). Their existing screens suffered rapid wear, allowing excessive fines (<10mm) into the charge.Solution: Installation of a heavyduty linear motion coke vibration screen with modular polyurethane decks sized at 10mm and 75mm.Results: Achieved consistent sizing with <3% fines in product fraction within one month; deck service life increased from 4 months to over 14 months; documented improvement in blast furnace stability.

[Coke Calcining Plant Product Grading] Challenge: A calciner needed to separate its output into three distinct commercial products (lump, nut, breeze). Manual sorting was costly,and their singledeck screens required frequent shutdowns for cleaning.Solution: Implementation of a tripledeck coke vibration screen with dedicated discharge chutes for each fraction.Results: Automated grading process increased sorting capacity by 200%; eliminated manual labor in that area; improved product purity allowed premium pricing for each specific grade.
