1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

Is your coke handling operation facing persistent bottlenecks and rising costs? La etapa de selección es a menudo un punto crítico de falla., impactando directamente el procesamiento posterior y la rentabilidad general de la planta. Los desafíos comunes incluyen:

Cegador & Continuar: Moisture and fine coke particles blind screen decks, mientras que el material de gran tamaño se traslada a los silos de productos terminados. Esto da como resultado un producto fuera de especificación., rechazos de clientes, and costly rehandling.
Tiempo de inactividad excesivo para mantenimiento: Fallas frecuentes en los rodamientos, reemplazos de tela de pantalla, and structural weld cracks demand constant attention from your maintenance crew, stealing valuable production hours.
Alto consumo de energía & Transmisión de vibración: Inefficient vibratory mechanisms consume excess power and transmit destructive forces to the support structure, leading to accelerated wear on the entire screening station.
Separación de grados inconsistente: An inability to maintain precise cut points leads to product contamination, reducing the market value of your metallurgical or foundry coke.

Are you evaluating how a purposeengineered Criba vibratoria de coque can reduce your total cost of ownership, increase screening availability above 95%, and ensure consistent product quality?

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

A Criba vibratoria de coque es de alta capacidad, heavyduty screening machine designed for the scalping, apresto, and dedusting of hot or cold metallurgical coke in battery, temple, and sorting plants. Its core function is to separate coke feedstock into precise size fractions (p.ej., coque de alto horno, coca de nuez, brisa) mientras se eliminan las multas.

Flujo de trabajo operativo:
1. Bulk coke from the quench car or feed conveyor is discharged onto the screen's robust feed box.
2. Highmagnitude, linear or elliptical vibratory motion stratifies the material bed and propels it across the multideck screening surfaces.
3. Undersize material passes through sequentially smaller apertures on each deck.
4. Correctly sized fractions discharge at designated outlets for conveyor transfer to storage bins or loading stations.
5. Material de gran tamaño (p.ej., +80milímetros) exits at the screen's discharge end for potential crushing or recirculation.

Ámbito de aplicación: Dimensionamiento primario y secundario del coque metalúrgico., recuperación de brisa de coque, precribado antes de la trituración. Not suitable for sticky materials without specialized deck technology or as a replacement for a crusher.
