1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

Is your petroleum coke processing operation struggling with inconsistent product quality and excessive maintenance costs? The screening phase for Chinese coke is a critical bottleneck where common failures directly impact profitability. ¿Estás enfrentando:
Transferencia de multas altas: Ineffective screening allows excessive fines into the finished product, degrading market value and risking customer rejection.
Premature Screen Clogging & Cegador: el abrasivo, often moist nature of delayed coke leads to rapid mesh blockage, requiriendo frecuentes, costly downtime for manual cleaning or panel replacement.
Desgaste excesivo del equipo: Standard screen decks and exciters fail under the continuous abrasion of coke particles, leading to unplanned breakdowns and high spare part consumption.
Rendimiento inconsistente: Inefficient vibration transmission and poor material flow result in uneven bed depth, limiting capacity and creating a process bottleneck.
Altos costos operativos: The cumulative effect of downtime, mano de obra de mantenimiento, reemplazos de piezas, and energy waste erodes your plant's operational margin.

La pregunta central para los gerentes de planta es: how can you achieve precise particle separation for Chinese coke while maximizing uptime and minimizing total cost of ownership?

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

The Chinese Coke Vibration Screen Processing Plant is a heavyduty, highamplitude screening system engineered specifically for the dry or slightly moist classification of petroleum coke (coque de petróleo). It is designed to separate green or calcined coke into precise fractions (p.ej., bulto, tuerca, chip) at high tonnage rates.

Flujo de trabajo operativo:
1. Introducción al feed: Raw or crushed coke is uniformly fed onto the robust feed box of the vibration screen.
2. Estratificación de alta intensidad: A powerful dualvibrator motor system drives a linear or elliptical motion, aggressively stratifying the material bed to bring fines into contact with the screen mesh.
3. Separación de tamaño precisa: Sized fractions pass through designated screen deck apertures (via multiple deck configurations), while oversize material conveys to the discharge end.
4. Descarga eficiente: Separated fractions are discharged via dedicated chutes into distinct collection hoppers or conveyors for downstream processing or storage.

Ámbito de aplicación & Limitaciones:
Alcance: Ideal for dry screening of green delayed coke and calcined petroleum coke in sizing applications from ~50mm down to ~0.5mm. Suitable for fixed plant installations in refineries, plantas de ánodo, and electrode material production facilities.
Limitaciones: No diseñado como tamiz de deshidratación para aplicaciones de lodos. Optimal performance assumes controlled feed moisture; excessively sticky or wet feed may require predrying or specialized screen surface treatments.
