1. ABERTURA ACIONADA POR PAINPOINT

Is your coke handling operation plagued by inefficient screening, excessive product degradation, e custos de manutenção não planejados? Para gerentes de fábrica e empreiteiros de engenharia, a suboptimal coke vibration screen directly impacts profitability through several critical challenges:

Product Loss and Contamination: Inconsistent particle separation leads to onspec coke being misdirected to fines or oversized fractions, resulting in revenue loss and product quality complaints.
Tempo de inatividade excessivo para manutenção: Frequent failures of screen decks, rolamentos, or vibration mechanisms halt entire processing lines, custando milhares por hora em perda de produção.
Altos custos operacionais: Inefficient screening requires higher energy consumption per ton processed. Premature wear of components due to poor design or material choice drives up spare parts inventory and labor expenses.
Dust Emission and Safety Hazards: Poorly sealed or overly aggressive vibrating screens can generate significant dust, criando problemas de conformidade ambiental e condições de trabalho inseguras.

Are you evaluating equipment that can deliver precise grading with higher availability and a lower total cost of ownership? The solution lies in specifying a coke vibration screen engineered for the specific abrasiveness and density of metallurgical or fuel coke.

2. VISÃO GERAL DO PRODUTO

UM coke vibration screen is a heavyduty industrial separator designed for the dry screening of crushed coke into precise size fractions. Its core function is to ensure consistent product quality for blast furnace charging, operações de fundição, or other industrial uses by efficiently removing fines and oversize material.

Fluxo de Trabalho Operacional:
1. Introdução ao feed: O coque triturado é alimentado uniformemente na plataforma de peneira inclinada(é) via a chute or conveyor.
2. Separação Vibratória: Alta intensidade, movimento vibratório linear ou circular estratifica o material. Smaller particles pass through the deck apertures (tamanho menor), enquanto partículas maiores viajam pela superfície do convés (tamanho grande).
3. Descarga de Fração: Separated streams—typically oversize, classificação do produto(é), and fines—are discharged via distinct outlets for further processing or shipment.

Escopo de aplicação & Limitações:
This equipment is designed for dry screening of bulk coke. It is not suitable for wet screening applications or for materials with high moisture content that cause blinding (clogging of screen openings). Optimal performance requires controlled feed rates and consistent feed size distribution as per design parameters.

6. CENÁRIOS DE APLICAÇÃO

[Alimentação de alto-forno para usina siderúrgica] Desafio: A major integrated steel mill experienced inconsistent blast furnace performance due to variability in coke size (2575milímetros). Their existing screens suffered rapid wear, allowing excessive fines (<10milímetros) into the charge.Solução: Installation of a heavyduty linear motion coke vibration screen with modular polyurethane decks sized at 10mm and 75mm.Resultados: Alcançado dimensionamento consistente com <3% fines in product fraction within one month; deck service life increased from 4 meses para acabar 14 meses; documented improvement in blast furnace stability.

[Coke Calcining Plant Product Grading] Desafio: A calciner needed to separate its output into three distinct commercial products (caroço, noz, brisa). Manual sorting was costly,and their singledeck screens required frequent shutdowns for cleaning.Solução: Implementation of a tripledeck coke vibration screen with dedicated discharge chutes for each fraction.Resultados: Automated grading process increased sorting capacity by 200%; eliminated manual labor in that area; improved product purity allowed premium pricing for each specific grade.
