1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

Is your coke handling operation plagued by persistent inefficiency and hidden costs? Para gerentes de planta y contratistas de ingeniería, the screening phase is a critical bottleneck with direct consequences for profitability. Los desafíos comunes incluyen:

Generación excesiva de multas: Inefficient screening leads to overbreaking of coke, converting valuable product into lowvalue fines. This represents a direct loss of revenue per ton.
Obstrucción frecuente de la pantalla & Falta del tiempo: Sticky coke particles and moisture cause blinding, Requiere paradas frecuentes para limpieza manual.. Este tiempo de inactividad no planificado detiene toda su línea de procesamiento.
Clasificación de productos inconsistente: An unreliable screen fails to deliver precise size separation, compromising the quality specifications demanded by your blast furnace or foundry customers, risking contract compliance.
Alto mantenimiento & Costos de reemplazo: Vibrating screens that are not engineered for the abrasive nature of coke suffer rapid wear on decks, ballestas, y excitadores, leading to high spare part consumption and labor costs.

Are you ready to reduce your costperton, aumentar la disponibilidad de la planta, and ensure a consistently onspec product? The solution lies in specifying a purposebuilt Criba vibratoria de coque.

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

A Criba vibratoria de coque is a heavyduty industrial screening machine designed for the dry separation of metallurgical coke into precise size fractions after crushing. Its core function is to ensure only correctly sized coke proceeds to blast furnace charging or shipment.

Flujo de trabajo operativo:
1. Introducción al feed: El coque triturado se alimenta uniformemente sobre la plataforma de cribado inclinada.(s) a través de una caja de alimentación o rampa.
2. Separación vibratoria: Alta intensidad, linear or circular vibration stratifies the material. Smaller particles pass through the screen media apertures (tamaño insuficiente), mientras que las partículas más grandes viajan por la superficie de la plataforma (demasiado grande).
3. Desvío de productos: Separated fractions are discharged via distinct chutes—typically into oversize (return for recrush), tamaño del producto, and fines hoppers.

Ámbito de aplicación: Primary sizing of metallurgical coke in coke plants, acerías, y terminales de manipulación de graneles. Adecuado para cribado de coque en frío o en caliente..

Limitaciones clave: Not designed for wet screening processes or for materials with extreme adhesive properties without specialized deck treatments.
