1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

Is your foundry or steel plant’s coke screening operation a persistent bottleneck? Alimentación inconsistente, material abrasivo, and demanding production schedules create significant challenges that directly impact your bottom line. ¿Estás experimentando:
Tiempo de inactividad excesivo: Frequent screen cloth changes and structural fatigue from highimpact loading, leading to hours of lost production per month.
Uncontrolled Emissions & Polvo: Fugitive coke fines creating environmental compliance headaches, housekeeping issues, and potential health hazards for operators.
Poor Fraction Accuracy: Inconsistent separation of breeze from furnacegrade coke, resulting in product quality issues and inefficient furnace operation.
Altos costos de mantenimiento: Premature failure of nonspecialized components due to abrasion and vibration stress, driving up spare part inventories and labor hours.

What if your screening station could deliver reliable, limpio, and efficient performance with significantly reduced operational intervention?

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

The Rohs Compliant Coke Vibration Screen is a heavyduty industrial screening machine engineered for the precise dry separation of metallurgical coke. It is designed to handle the abrasive nature and specific size distribution requirements of coke prior to blast furnace charging.

Flujo de trabajo operativo:
1. Alimentación controlada: Coke is delivered via conveyor onto the screen’s robust feed box, which evenly distributes material across the full width of the screening surface.
2. Separación de alta eficiencia: A dualvibrator motor drive generates a linear or elliptical vibratory motion, stratifying and conveying material across the screen decks. Precisely sized apertures separate furnace coke (demasiado grande) from coke breeze (tamaño insuficiente).
3. Descarga limpia: Separated fractions are discharged via dedicated chutes—furnacegrade coke to the charge system, fines to collection—minimizing intercontamination.

Ámbito de aplicación & Limitaciones:
Alcance: Ideal for dry screening of metallurgical coke in steel plants, fundiciones, and coke production facilities. Effective for size ranges typically from 25mm to 80mm.
Limitaciones: No está diseñado para aplicaciones de cribado húmedo ni para materiales con alto contenido de humedad que cause cegamiento.. Maximum lump size is limited by specific model feed inlet dimensions.
