1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

¿Su operación de manipulación de coque está plagada de cuellos de botella persistentes y costos de mantenimiento en aumento?? Para gerentes de planta que supervisan el cribado de coque, Los desafíos comunes impactan directamente en el resultado final.. Excessive fines carryover due to inefficient separation can degrade product quality and reduce saleable yield. Cambios frecuentes de tela de pantalla, caused by premature wear from abrasive coke, lead to hours of unplanned downtime and high consumables expenditure. Las fallas en el aislamiento de vibraciones transfieren fuerzas destructivas a las estructuras de soporte., creando preocupaciones sobre la integridad de los activos a largo plazo. Moreover, inconsistent feed rates and moisture content can overwhelm standard screens, causing blinding and a significant drop in throughput. ¿Se enfrenta a costos operativos crecientes?, disponibilidad impredecible, and an inability to meet stringent sizing specifications consistently? The reliability of your entire downstream process hinges on the performance of this critical node.

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

La criba vibratoria de coque es de uso pesado., linear motion screening machine engineered for the precise size classification of metallurgical coke and similar abrasive materials in bulk handling plants. Its core function is to separate crushed coke into defined fractions (p.ej., coque de alto horno, coca de nuez) mientras se eliminan las multas.

Flujo de trabajo operativo:
1. Alimentar & Distribución: Crushed coke is evenly distributed across the full width of the screen via a robust feed box.
2. Estratificación & Separación: Dual counterrotating exciters generate a linear vibrating motion, stratifying material and conveying it along the deck while precise sizing occurs through the screen meshes.
3. Descarga de fracciones: Correctly sized oversize material discharges from the front of the deck; onsize material passes through to lower decks or chutes; fines are separated and discharged separately.

Ámbito de aplicación: Cribado primario y secundario de coque metalúrgico., recrusher feed screening, separación de brisa de coque.
Limitaciones: No diseñado para pegajoso, highly cohesive materials without specialized deck systems. El tamaño máximo de los grumos está limitado por el diseño del conducto de alimentación y la apertura de la plataforma..
