1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

Are your coke screening operations plagued by persistent inefficiencies that erode profitability? Para gerentes de planta y contratistas de ingeniería, the challenges of screening bulk coke are familiar yet costly. Excessive fines generation due to aggressive vibration directly impacts product yield and revenue. Cambios frecuentes de tela de pantalla, driven by premature wear from abrasive coke, result in significant downtime and high consumable costs. Inconsistent particle size distribution can lead to downstream process issues in blast furnaces or foundries, affecting overall plant efficiency. Moreover, structural failures in the screen body or deck from highcycle fatigue lead to unplanned maintenance events and safety concerns. Are you managing vibration isolation problems that transfer stress to support structures, creating longterm integrity issues? The cumulative effect is measurable: rendimiento reducido, elevated maintenance budgets, y calidad del producto comprometida.

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

La criba vibratoria de coque OEM es de servicio pesado., linear or elliptical motion vibrating screen engineered specifically for the sizing, especulación, and dedusting of metallurgical and foundry coke. Its design prioritizes durability and precise material stratification under highabrasion conditions.

Flujo de trabajo operativo:
1. Alimentar & Distribución: Bulk coke is fed onto the robust feed box, que distribuye uniformemente el material en todo el ancho de la plataforma superior.
2. Estratificación & Apresto: El movimiento vibratorio controlado estratifica el material por tamaño; larger particles convey along the deck while smaller fractions pass through accurately sized screen apertures.
3. Separación de productos: Multiple deck configurations allow for the precise separation of multiple product streams (p.ej., coca de nuez, brisa).
4. Descargar: Sized fractions are discharged into separate chutes for downstream processing or shipment.

Ámbito de aplicación: Dimensionamiento primario del coque runofoven., removal of coke breeze (multas), scalping of oversized material, and dedusting applications in coke handling plants, acerías, y fundiciones.

Limitaciones: No diseñado para cribado húmedo o materiales pegajosos.. Maximum capacity and separation efficiency are subject to specific moisture content, gradación de alimentación, and desired cut points.

6. ESCENARIOS DE APLICACIÓN

Planta siderúrgica integrada: preparación de alimentación para altos hornos

Desafío: A major steel producer faced inconsistent nut coke size (1025milímetros) fed to the blast furnace due to rapid cloth wear on existing screens. Multas (<10milímetros) contamination exceeded tolerances, affecting furnace permeability and increasing fuel rate.
Solución: Implementation of a twodeck OEM Coke Vibration Screen featuring polyurethane panel decks on both levels for extended wear life in the critical sizing stage.
Resultados: Screen panel life increased from an average of 35 días para terminar 75 días. Nut coke product consistency improved significantly; fines content was maintained below target threshold (<5%). Annual savings were realized through reduced cloth inventory ($18k) and lower downtime ($45k estimated production value).
