1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

Are your coke screening operations plagued by persistent, costosas ineficiencias? Plant managers and engineering contractors face significant challenges in maintaining consistent product quality and throughput. Los puntos débiles comunes incluyen:
Cegador & Continuar: Moisture and fine particles adhere to screen decks, blinding apertures and forcing material carryover. Esto da como resultado un producto fuera de especificación., mayores cargas de trituración, and wasted yield.
Tiempo de inactividad excesivo & Mantenimiento: Frequent screen cloth changes and structural repairs due to aggressive vibration or material abrasion halt your production line, impactando directamente su resultado final.
Tamaño inconsistente & Pérdida de rendimiento: Ineffective screening leads to missized coke fractions, compromising blast furnace efficiency for your customers and eroding your profit margins.
Altos costos operativos: Fallo prematuro de componentes, Alto consumo de energía debido a accionamientos ineficientes., and laborintensive cleaning procedures inflate your costperton.

Is there a screening solution engineered to withstand the abrasive nature of metallurgical coke while delivering precise separation with maximum uptime?

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

The ISOCertified Coke Vibration Screen is a heavyduty linear or elliptical motion vibrating screen specifically engineered for the dry separation of metallurgical coke into precise size fractions (p.ej., coque de alto horno, coca de nuez, brisa). Its robust design addresses the unique abrasiveness, densidad, and size range of coke particles.

Flujo de trabajo operativo:
1. Alimentar & Distribución: Sized coke from crushers is evenly distributed across the full width of the screen’s feed box.
2. Estratificación & Separación: HighGforce vibration stratifies material; fines pass through the configured screen cloth apertures while oversize travels toward the discharge end.
3. Descargar: Correctly sized fractions are discharged into separate chutes or conveyors for stockpiling or shipment.

Ámbito de aplicación: Primary and secondary screening of metallurgical coke in coke plants, acerías, y terminales de manipulación de graneles. Ideal for sizing ranges from 80mm down to 05mm breeze.

Limitaciones: Not designed for wet screening applications or for materials with extreme temperature (>150°C) without specific modifications.
