1. ABERTURA ACIONADA POR PAINPOINT

Is your coke handling operation struggling with inconsistent product quality, geração excessiva de multas, and unplanned maintenance cycles? Inefficient screening directly impacts your bottom line through lost product, higher energy consumption in downstream processes, and costly downtime for screen deck replacements. Considere estes desafios comuns:
Cegagem & Carryover: Moisture or sticky fines blind screen meshes, reducing effective screening area and forcing oversized particles into the finished product, compromising quality.
Premature Deck Failure: The abrasive nature of hot coke accelerates wear on screen panels and support structures, levando a frequentes, disruptive shutdowns for replacements.
Inefficient Fines Separation: Inadequate separation results in valuable coke fines being lost to waste or oversized material overworking crushers, increasing power costs and wear.
Excessive Vibration Transmission: Poorly isolated vibration damages support structures and adjacent equipment, creating safety concerns and secondary maintenance issues.

Are you seeking a solution that maximizes uptime, protects product specification integrity, and reduces your total cost of ownership per ton screened?

2. VISÃO GERAL DO PRODUTO

The Coke Vibration Screen is a heavyduty industrial screening machine designed for the hightemperature, highabrasion separation of metallurgical coke. Its primary function is to reliably separate crushed coke into precise size fractions (por exemplo, blast furnace coke, coque de nozes) while removing fines.

Fluxo de Trabalho Operacional:
1. Introdução ao feed: Crushed coke is uniformly distributed onto the feed end of the screen via a chute or conveyor.
2. Stratified Vibration: A highGforce vibratory motion stratifies the material bed, forcing fines and nearsize particles down to the screen media surface.
3. Size Separation: Particles smaller than the aperture pass through (tamanho menor), while larger particles travel across the deck as oversize.
4. Descarga: Separated fractions are discharged via dedicated chutes for further processing or shipment.

Escopo de aplicação & Limitações:
Escopo: Ideal for dry screening of hot or cold metallurgical coke in coke plants, steel mills, and foundries. Suitable for sizing (single or multideck) and dedusting applications.
Limitações: Not designed for wet screening or slurry applications. Maximum feed temperature typically capped by seal and bearing specifications (commonly up to 150200°C). Extremely sticky materials may require pretreatment or specialized deck cleaning systems.

3. RECURSOS PRINCIPAIS

HeavyDuty Box Beam Deck Support | Base Técnica: Reinforced structural design with continuous weldment | Benefício Operacional: Eliminates deck flexing under load for consistent stratification; withstands impact from large coke lumps | Impacto do ROI: Extends screen cloth life by up to 30%, reducing part change frequency and downtime.

HighTemperature / AbrasionResistant Liners | Base Técnica: Bolton wear plates at feed points made from AR400 or equivalent steel | Benefício Operacional: Protects main deck structure from direct impact and abrasion damage | Impacto do ROI: Lowcost liner replacement vs. full deck repair; maintains structural integrity for years.

DualVibrator Drive System | Base Técnica: Two synchronized externallymounted vibrator motors generating linear motion | Benefício Operacional: Simplified maintenance access; balanced force distribution; easy amplitude adjustment via motor weights | Impacto do ROI: Higher reliability than shaftdriven designs; modular motor replacement minimizes downtime.

MultiStage Rubber Isolation System | Base Técnica: Layered rubber shear mounts or coil spring isolators | Benefício Operacional: Absorbs over 95% of dynamic forces before they reach the support structure | Impacto do ROI: Eliminates costly structural reinforcement needs; protects surrounding equipment from vibration damage.

QuickChange Deck Tensioning System | Base Técnica: Modular tensioning rails with bolton wedge clamps | Benefício Operacional: Allows single operator to change screen panels in under one hour without specialized tools | Impacto do ROI: Reduces planned maintenance window by over 60%, aumentando a disponibilidade da planta.

DustEncapsulated Bearing Housings | Base Técnica: Labyrinth seals with grease purge fittings on vibrator shaft bearings | Benefício Operacional: Prevents ingress of fine abrasive coke dust into bearing assemblies | Impacto do ROI: Extends critical bearing service life by 23x, preventing catastrophic drive failure.

6. CENÁRIOS DE APLICAÇÃO

Steel Mill Coke Handling Plant

Desafio: A major integrated steel mill experienced rapid blinding of wire mesh screens when processing coke with elevated moisture content (~8%), causing oversize contamination in blast furnace feed every 1012 dias.
Solução: Implementation of a tripledeck Coke Vibration Screen fitted with nonblinding polyurethane screen panels featuring tapered apertures and a highGforce linear drive system.
Resultados: Screening intervals extended to over 45 days between scheduled cleanings. Oversize contamination reduced by >98%, ensuring consistent blast furnace burden permeability.

Merchant Coke Producer

Desafio: Excessive generation of 5mm fines during final product screening was eroding profit margins due to product degradation and lost saleable tonnage.
Solução: Installation of a doubledeck Coke Vibration Screen optimized for precise cutpoint separation at 6mm and 25mm using a dualvibrator drive system for stable stratification control.
Resultados: Fines generation (5milímetros) reduced by an average of 22%. This resulted in an increase in saleable nut coke (+6mm/25mm) fraction yield worth approximately €120k annually at prevailing prices.
