1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

Are you managing a coke handling or screening operation where efficiency losses directly impact your bottom line? The challenges of screening premium metallurgical coke are wellknown: inconsistent particle size distribution leads to blast furnace instability, excessive fines generation wastes valuable product, and unscheduled downtime for screen maintenance halts your entire production line. Each hour of lost screening capacity can cost thousands in delayed shipments and process bottlenecks. ¿Cómo se logra la coherencia?, highvolume separation while minimizing abrasive wear on equipment? What solutions exist to reduce the operational cost per ton of screened coke and protect your critical downstream processes? The answer lies in selecting a vibration screen engineered specifically for the harsh demands of premium coke.

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

The Premium Coke Vibration Screen is a heavyduty, linear motion screening machine designed for the highcapacity sizing and scalping of metallurgical coke. Its robust construction addresses the abrasive nature and significant bulk density of coke particles.

Flujo de trabajo operativo:
1. Alimentar & Distribución: Coke is fed onto the screen via a regulated feed chute, distributing material evenly across the full width of the screen deck.
2. Linear Stratification & Separación: Twin counterrotating vibrator motors generate a forceful linear motion, stratifying material by size and conveying it across the screen surface. Oversize material travels over the deck apertures, while correctly sized particles pass through.
3. Descargar: Separated fractions are discharged into designated chutes or conveyors for routing to storage or downstream processes.

Ámbito de aplicación: Dimensionamiento primario (especulación) de coque runofoven, eliminación de brisa (multas) from furnace feed, and final product grading. Ideal for hightonnage applications in coke plants, acerías, y terminales de manipulación de graneles.

Limitaciones: Not designed for sticky or moist materials without specialized deck treatments. Maximum efficiency is achieved with controlled feed rates as per engineered capacity.

6. ESCENARIOS DE APLICACIÓN

Integrated Steel Plant Blast Furnace Feed

Challenge A major steel producer faced inconsistent blast furnace performance linked to variable coke size distribution from their existing screens. Excessive fines increased fuel rate and reduced permeability.
Solution Installation of two highcapacity Premium Coke Vibration Screens configured for precise removal of sub20mm fractions prior to furnace charging.
Results Achieved consistent furnace feed with <5% fines content (<10milímetros). Field data shows a documented reduction in coke rate by approximately 2%, alongside improved gas flow stability.

Merchant Coke Production & Calificación

Challenge A merchant coke plant needed to increase graded product output (coca de nuez, coque de fundición) but was limited by frequent screen cloth changes causing bottlenecks in their bagging lines.
Solution Implementation of a multideck Premium Coke Vibration Screen with quickchange polyurethane panels tailored for multiple cut points.
Results Increased overall grading plant availability by an estimated three hours per week due to faster media changes. The durability of the panels also reduced annual consumable costs by an estimated $18k USD per line.
