1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

Are your coke screening operations plagued by persistent inefficiencies that directly impact your bottom line? Los desafíos comunes incluyen:

Tiempo de inactividad excesivo: Frequent screen cloth blinding and premature wear from abrasive coke fines, leading to unscheduled maintenance stops and lost production hours.
Clasificación de productos inconsistente: Inefficient separation resulting in offspec material—oversize particles contaminating the nut coke fraction or excessive fines in the blast furnace feedstock—compromising downstream process efficiency.
Altos costos operativos: Constant replacement of screen decks, excessive energy consumption from inefficient vibration mechanisms, and high labor costs for manual clearing and maintenance.
Preocupaciones por la integridad estructural: Vibration transmission to support structures causing fatigue cracks and foundation issues, creating longterm plant safety and capital expenditure risks.
Emisión de polvo & Derrame: Poor sealing and excessive vibration exacerbate housekeeping issues, creating environmental control challenges and product loss.

Is your current screening solution a source of recurring cost and reliability headaches? ¿Qué sería un 2030% reduction in maintenance intervals and a 15% improvement in screening efficiency mean for your annual operational budget?

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

The Coke Vibration Screen is a heavyduty, highcapacity screening machine engineered for the precise size classification of metallurgical coke. It separates crushed coke into defined fractions—such as blast furnace coke, coca de nuez, and breeze—critical for optimal furnace operation.

Flujo de trabajo operativo:
1. Introducción al feed: Crushed coke is uniformly distributed onto the feed box of the inclined screen deck(s).
2. Separación vibratoria: A highefficiency vibrator assembly imparts a linear or elliptical motion, stratifying material and propelling it across the screening surface.
3. ​​SizeBased Stratification: Particles smaller than the screen aperture fall through as undersize, while larger particles travel across the deck to discharge as oversize.
4. Descarga de fracciones: Separated material streams are discharged via dedicated chutes into designated collection hoppers or conveyors for further processing or shipment.

Ámbito de aplicación & Limitaciones:
Alcance: Ideal for primary sizing of hot or cold metallurgical coke in coke plants, acerías, y terminales de manipulación de graneles. Effective for capacities ranging from 200 a 1500+ toneladas por hora.
Limitaciones: No diseñado para materiales pegajosos sin tratamiento previo. (p.ej., preheating). Performance is contingent on proper feed rate control and consistent moisture content management.
