1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

Is your coke handling and classification process a source of chronic downtime and cost overruns? Para gerentes de planta que supervisan el cribado de coque, common operational challenges include:
Cegador & Continuar: Bien, Cubiertas de pantalla ciega de partículas de coque pegajosas, while oversized material carries over into finished product bins, compromising quality and forcing manual intervention.
Ciclos de mantenimiento excesivos: The abrasive nature of coke accelerates wear on screen panels, aspectos, y excitadores, llevando a frecuentes, unplanned shutdowns for parts replacement.
Separación de multas ineficiente: Inconsistent vibration patterns fail to properly separate breeze from nut coke, resulting in product specification misses and lost revenue from misclassified material.
Fatiga estructural & Falla: Highcycle operations under heavy load lead to weld cracks and structural failures in the screen body, creating major capital repair events.

These issues translate directly into quantifiable losses: Horas de producción perdidas por mes., rising spare parts inventories, and inconsistent product quality affecting customer contracts. How do you achieve reliable separation with minimal maintenance? The answer lies in specifying a purposeengineered Criba vibratoria de coque.

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

A Criba vibratoria de coque es una máquina de cribado industrial de alta resistencia diseñada para el descalzado, apresto, y desempolvado de coque metalúrgico y coque de petróleo. Its core function is to separate bulk coke into precise fractions (p.ej., blast furnace nut coke, coque de fundición, brisa) using controlled vibratory motion.

Flujo de trabajo operativo:
1. Alimentar & Distribución: Bulk coke is fed onto the screen’s robust feed box, which evenly distributes material across the full width of the first screening deck.
2. Estratificación & Separación: Highintensity vibration stratifies the material; fines pass through upper deck apertures while larger particles travel across the deck surface.
3. Apresto & Descargar: Multideck configurations allow for sequential sizing. Correctly sized fractions discharge from designated discharge spouts into separate conveyors or bins for downstream processing.

Ámbito de aplicación: Primary sizing of ovendischarged coke, scalpandscreen circuits in byproduct plants, final product grading before shipment, y aplicaciones de desempolvado.

Limitaciones: No diseñado para aplicaciones de cribado húmedo o lodo. Maximum lump size is constrained by feed chute and deck aperture design; typically handles feed sizes up to 300mm.
