1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

Is your coke handling operation plagued by inconsistent product quality, generación excesiva de multas, and unplanned maintenance stops? Inefficient screening directly impacts your bottom line through lost product yield, increased downstream equipment wear, and costly process interruptions. ¿Estás enfrentando actualmente:

Contaminación del producto: Inadequate separation of breeze from furnacegrade coke, leading to customer rejections or penalties for offspec material.
Tiempo de inactividad excesivo: Frequent screen deck changes and bearing failures on vibrating screens due to the abrasive nature of hot coke, detener toda su línea de procesamiento.
Altos costos operativos: Premature wear of screen cloths and components from impact and abrasion, coupled with high energy consumption from inefficient vibratory motion.
Dust and Emission Challenges: Poorly sealed or inefficient screening contributing to fugitive dust, creating environmental and housekeeping issues.

The right industrial vibrating screen is not just a piece of equipment; it's a critical process gatekeeper for profitability. How do you ensure maximum throughput of onspec coke while minimizing lifecycle costs?

2. DESCRIPCIÓN GENERAL DEL PRODUCTO: Criba vibratoria de coque de servicio pesado

Este equipo es de alta capacidad., linear motion vibrating screen engineered specifically for the scalping, apresto, and dedusting of metallurgical coke and coke breeze in harsh operating environments. Su diseño prioriza la durabilidad, precisión de separación, and minimal maintenance.

Flujo de trabajo operativo:
1. Alimentar & Distribución: Hot or cooled coke is uniformly fed onto the robust feed box, distributing material across the full width of the top deck.
2. Separación estratificada: The dualmass vibratory system drives a linear motion, stratifying material by size. Larger furnacegrade coke moves across the upper deck(s), while smaller fractions pass through to lower decks or collection chutes.
3. Descarga de producto dimensionado: Precisely sized fractions are discharged from designated discharge spouts—oversize (p.ej., +50milímetros), producto (p.ej., 2550milímetros), and breeze (p.ej., 25milímetros)—for routing to blast furnaces or other processes.

Ámbito de aplicación: Primary and secondary screening of metallurgical coke at coke plants, acerías, and transfer stations. Suitable for hot or cold feed conditions.

Limitaciones: Not designed for sticky or highly moist materials without specialized deck treatments. Maximum feed temperature must be specified at time of order to ensure proper component selection.
