1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

Is your coke handling and screening operation a constant source of bottlenecks, dolores de cabeza de mantenimiento, and product quality inconsistencies? Para gerentes de planta y contratistas de ingeniería, the challenges of screening coke are distinct and costly.

Excessive Downtime for Screen Deck Changes: Frequent blinding and wear on traditional screens force lengthy, laborintensive media replacements, detener toda su línea de procesamiento.
Generación de multas descontroladas & Degradación del producto: Aggressive vibration or improper screen action can break down coke lumps, creating excess fines that devalue your product and reduce yield.
Altos costos de mantenimiento & Component Fatigue: The abrasive nature of coke accelerates wear on screen decks, ballestas, y mecanismos vibradores, leading to unpredictable repair cycles and spare parts inventory costs.
Separación ineficiente & Missed Contaminants: Inconsistent material travel or insufficient screening intensity can allow oversized contaminants or undersized fractions to pass, compromising blast furnace feed quality.

Are you evaluating equipment that can extend service intervals, proteger la integridad del producto, and deliver a measurable return on investment through sustained throughput? The engineering behind your Criba vibratoria de coque is critical to solving these operational challenges.

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

La criba vibratoria de coque HeavyDuty es una criba de alta capacidad, linear motion screening machine engineered for the precise sizing and scalping of metallurgical coke in bulk material handling systems. Its design prioritizes durability and consistent performance in harsh, ambientes abrasivos.

Flujo de trabajo operativo:
1. Alimentación controlada: Coke from a crusher or feed conveyor is evenly distributed across the full width of the screen’s inlet.
2. Linear Stratification & Apresto: Los dos motores vibradores contrarrotativos generan un movimiento de lanzamiento lineal.. Esta acción estratifica el lecho de material., allowing finer particles to contact the screen media while conveying larger lumps toward the discharge end.
3. Separación precisa: Sized fractions pass through defined screen deck apertures (typically wire mesh or polyurethane panels) into separate discharge chutes.
4. Descarga eficiente: Coca-Cola del tamaño correcto (p.ej., coque de alto horno) is discharged as product, while oversize material (p.ej., +80milímetros) or undersize fines (p.ej., 25milímetros) are diverted for recirculation or disposal.

Ámbito de aplicación: Primary sizing/scalping of metallurgical coke postcrushing; separación de brisa de coque; dedusting applications.
Limitaciones: Not designed for sticky or moist materials without pretreatment; maximum feed size is limited by inlet design and deck robustness.
