1. ABERTURA ACIONADA POR PAINPOINT

Is your coke handling operation plagued by inconsistent product quality, geração excessiva de multas, and unplanned maintenance stops? Inefficient screening directly impacts your bottom line through lost product yield, increased downstream equipment wear, and costly process interruptions. Você está enfrentando atualmente:

Contaminação do Produto: Inadequate separation of breeze from furnacegrade coke, leading to customer rejections or penalties for offspec material.
Tempo de inatividade excessivo: Frequent screen deck changes and bearing failures on vibrating screens due to the abrasive nature of hot coke, interrompendo toda a sua linha de processamento.
Altos custos operacionais: Premature wear of screen cloths and components from impact and abrasion, coupled with high energy consumption from inefficient vibratory motion.
Dust and Emission Challenges: Poorly sealed or inefficient screening contributing to fugitive dust, creating environmental and housekeeping issues.

The right industrial vibrating screen is not just a piece of equipment; it's a critical process gatekeeper for profitability. How do you ensure maximum throughput of onspec coke while minimizing lifecycle costs?

2. VISÃO GERAL DO PRODUTO: Peneira vibratória de coque resistente

Este equipamento é de alta capacidade, linear motion vibrating screen engineered specifically for the scalping, dimensionamento, and dedusting of metallurgical coke and coke breeze in harsh operating environments. Seu design prioriza durabilidade, precisão de separação, and minimal maintenance.

Fluxo de Trabalho Operacional:
1. Alimentar & Distribuição: Hot or cooled coke is uniformly fed onto the robust feed box, distributing material across the full width of the top deck.
2. Separação Estratificada: The dualmass vibratory system drives a linear motion, stratifying material by size. Larger furnacegrade coke moves across the upper deck(é), while smaller fractions pass through to lower decks or collection chutes.
3. Sized Product Discharge: Precisely sized fractions are discharged from designated discharge spouts—oversize (por exemplo, +50milímetros), produto (por exemplo, 2550milímetros), and breeze (por exemplo, 25milímetros)—for routing to blast furnaces or other processes.

Escopo de aplicação: Primary and secondary screening of metallurgical coke at coke plants, siderúrgicas, and transfer stations. Suitable for hot or cold feed conditions.

Limitações: Not designed for sticky or highly moist materials without specialized deck treatments. Maximum feed temperature must be specified at time of order to ensure proper component selection.
