1. PAINPOINT DRIVEN OPENING

Are you facing persistent, costly inefficiencies in your final product screening? Operational challenges with standard vibrating screens for coke classification directly impact your bottom line and plant reliability. Consider these common issues:

Blinding & Carryover: Fine, abrasive coke particles blind screen meshes, while oversized material carries over into finished product silos. This results in offspec product, customer rejections, and costly reprocessing.
Excessive Maintenance Downtime: The constant impact of hard, sharp coke fractures screen decks and fatigues side plates. Frequent shutdowns for panel replacement and structural repairs halt your processing line.
High Energy & Operating Costs: Inefficient vibration mechanisms require excessive power to achieve minimal material stratification. Coupled with high wearpart consumption, your costperton processed remains uncompetitive.
Inconsistent Product Gradation: Variable feed rates and traditional screen action lead to inconsistent separation at cut points (e.g., 25mm, 30mm). This variability compromises the uniformity required for blast furnace or foundry operations.

How can you achieve precise, reliable coke sizing with lower operational expenditure and maximized equipment availability? The solution requires a purposeengineered approach to vibration screening.

2. PRODUCT OVERVIEW

The Luxury Coke Vibration Screen is a heavyduty, linear motion screening machine engineered specifically for the dry classification of metallurgical coke and calcined petroleum coke. It separates crushed coke into precise fractions—such as nut coke, breeze, or furnacegrade coke—based on particle size distribution.

Operational Workflow:
1. Controlled Feed: Sized crusher discharge is uniformly distributed across the full width of the screen inlet via an integrated feed box.
2. Efficient Stratification: A highGforce, linear vibration pattern throws material upward and forward, rapidly stratifying fines to the bottom layer for contact with the screen media.
3. Precise Separation: Sized particles pass through accurately sized screen panel apertures, while oversize material travels along the deck to the discharge end.
4. Clean Discharge: Properly sized fractions are discharged via separate chutes into designated product streams for storage or transport.

Application Scope & Limitations:
Scope: Ideal for dry screening of hot or cold metallurgical coke (Met Coke), anode coke, and calcined petroleum coke in sizing capacities from 5mm to 80mm. Suitable for sinter plants, blast furnace operations, and carbon anode production plants.
Limitations: Not designed for wet screening applications or for materials with high moisture content that causes adhesion. Not recommended for primary crushing duties or extremely abrasive noncarbonaceous materials without specific configuration review.
