1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

Is your coke handling operation plagued by persistent inefficiencies that erode profitability? Para gerentes de planta y contratistas de ingeniería, the screening phase is a critical bottleneck with direct consequences.

Cegador & Continuar: Moisture and fine coke particles blind traditional screens, reduciendo el área de detección efectiva. This leads to undersized material contaminating your product stream or oversized particles damaging downstream crushers, causing unplanned maintenance.
Tiempo de inactividad excesivo & Mantenimiento: Conventional screens with complex drive mechanisms and numerous bearings require frequent lubrication and are prone to failure. Each hour of unscheduled downtime represents significant lost production revenue.
Inefficient Separation & Inconsistencia del producto: Inconsistent feed rates or particle distribution result in poor grade control. Are you facing rejections or price penalties due to product not meeting precise size specifications?
Fatiga estructural & Desgaste prematuro: The abrasive nature of coke accelerates wear on screen decks and side plates. Premature replacement of these components is a recurring capital expense.
High Energy Consumption for Limited Output: Older screening technology often operates at a fixed, high energy draw regardless of load, leading to inefficient power use per ton of material processed.

La pregunta se vuelve: ¿Cómo se logra ser confiable?, consistent coke classification while controlling operational costs and maximizing equipment uptime?

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

La criba vibratoria de coque personalizada es de uso pesado., linear motion vibrating screen engineered specifically for the harsh demands of coke sorting and sizing operations. It separates raw or processed coke into two or more precise fractions based on particle size.

Flujo de trabajo operativo:
1. Alimentación controlada: Coke is fed onto the inlet head of the screen via a conveyor or feeder.
2. Separación estratificada: The highGforce linear vibration stratifies the material bed, forcing fines downward through the apertures of the robust screen deck panels.
3. Efficient Conveyance: The linear motion efficiently conveys oversize material along the deck length to the discharge end.
4. Clean Split: Properly sized undersize material passes through the deck, while oversize continues to the designated discharge spout.
5. Operación continua: The system operates continuously under heavy load with minimal performance degradation.

Ámbito de aplicación: Sizing of foundry coke, coque metalúrgico (metcoke), coque de petróleo (coque de petróleo), and anodegrade coke in quenching stations, blast furnace feed lines, and calcining plants.

Limitaciones: No diseñado para pegajoso, highly cohesive materials without pretreatment or specialized deck technology. Maximum efficiency requires controlled, even feed distribution across the full screen width.

6. ESCENARIOS DE APLICACIÓN

Metallurgical Coke Plant – Blast Furnace Feed Line

Desafío:A major steel producer experienced frequent blinding on circular screens handling quenched coke (~8% moisture). This caused inconsistent sizing feeding their blast furnaces (~25mm cut), leading to irregular furnace operation and increased fuel rate.Solution:The installation of a custom linear motion vibration screen equipped with nonblinding polyurethane tensioned decks designed specifically for damp materials.Resultados: La eficiencia del cribado se estabilizó en >94%. Carryover of fines was reduced by over 80%. Plant engineers reported a measurable improvement in blast furnace consistency within one month.

Calcined Petroleum Coke Facility – Final Product Sizing

Desafío:The final sizing stage for anodegrade CPC required an extremely clean separation at multiple cut points (p.ej., 4mm +1mm). Existing screens generated excessive dust (1fracción mm) due to poor stratification.Solution:A custom tripledeck vibration screen was implemented featuring fully enclosed dusttight housings on each deck discharge.Resultados:La pureza del producto mejoró significativamente,directly impacting sales pricing.Dust emissions at the screening station were contained,and recovered ultrafines were captured as a separate,salable product stream,increasing overall plant yield.
