1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

¿Su operación de manipulación de coque está plagada de cuellos de botella persistentes?, generación excesiva de multas, y costos de mantenimiento no planificados? Para gerentes de planta que supervisan el cribado de coque, Los desafíos comunes impactan directamente en el resultado final.:
Cegador & Falta del tiempo: Moisture and sticky fines blind screen decks, halting production for manual cleaning. Each hour of downtime can cost thousands in lost throughput.
Separación ineficiente: Inconsistent particle size distribution leads to underperforming blast furnaces or rejected product from battery clients.
Alta carga de mantenimiento: Conventional screens with numerous moving parts and intense vibration require frequent bearing changes, spring replacements, and structural welds.
Generación excesiva de multas: Agresivo, inefficient screening action breaks down coke, creating excess fines that degrade product value and create handling issues.
Ineficiencia energética: Overpowered drives running constantly to overcome blinding waste significant electrical power.

Are you searching for a screening solution that delivers consistent cut points, maximiza el tiempo de actividad, y reduce el coste total de propiedad?

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

The Coke Vibration Screen is a highcapacity, heavyduty screening machine engineered for the precise separation of metallurgical coke and coke breeze in demanding processing environments. Its core function is to reliably size coke into specific fractions (p.ej., coque de alto horno, coca de nuez) mientras se eliminan las multas.

Flujo de trabajo operativo:
1. Alimentar & Distribución: Runofoven or crushed coke is fed onto the screen’s robust feed box, que distribuye uniformemente el material en todo el ancho de la plataforma de cribado.
2. Separación estratificada: A dualmass vibratory system drives a linear or elliptical motion, material estratificante. Larger particles convey across the deck surface while smaller particles pass through the screen apertures.
3. Product Stream Segregation: Separated fractions are discharged via dedicated chutes—typically oversized material (overs), onspec product (medios), y multas (debajo)—for routing to storage or downstream processes.

Ámbito de aplicación: Cribado primario y secundario de coque metalúrgico., separación de brisa de coque, sinter feed preparation, and prescreening for crushing circuits.

Limitaciones: No diseñado para pegajoso, nonfreeflowing materials without specialized deck technology. El tamaño máximo de los grumos está limitado por las especificaciones de diseño del conducto de alimentación y de la plataforma..
