1. ABERTURA ACIONADA POR PAINPOINT

Sua operação de manuseio de coque está atormentada por gargalos persistentes?, custos excessivos de manutenção, e qualidade do produto inconsistente? Para gerentes de fábrica que supervisionam a triagem de coque, desafios comuns impactam diretamente os resultados financeiros:
Cegagem & Transferir: Moisture and fine particles blind screen decks, reducing effective screening area and forcing material carryover. This contaminates product grades and creates costly rehandling.
Tempo de inatividade excessivo & Manutenção: Standard vibrators and bearings fail under continuous heavy loads, levando a paralisações não planejadas. Dados do setor indicam que algumas operações perdem 15% of available runtime to screen maintenance.
Fadiga Estrutural & Frame Cracking: The abrasive nature of coke and highcycle vibration induce metal fatigue in inadequately designed frames, resulting in catastrophic failures and expensive structural repairs.
Separação ineficiente de multas: Padrões de vibração inconsistentes não conseguem separar adequadamente a brisa do coque de nozes, leaving potential revenue unrealized and causing downstream process issues.

Are you searching for a screening solution engineered to withstand the specific demands of coke classification with higher availability and lower total cost of ownership?

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

The HeavyDuty Coke Vibration Screen is a bruteforce linear motion screening machine engineered for the primary sizing, escalpelamento, and dedusting of metallurgical and petroleum coke. Its design prioritizes structural integrity and material stratification to handle hightonnage, abrasive applications.

Fluxo de Trabalho Operacional:
1. Alimentação controlada: Coke is directed onto the robust feed box, which distributes material evenly across the full width of the primary screen deck.
2. HighEnergy Stratification: A dualshaft, synchronized vibrator assembly generates a linear throwing motion. This action aggressively stratifies the material bed, forcing fines downward for rapid separation.
3. Dimensionamento preciso: Sized fractions pass through defined deck apertures (typically wire mesh or polyurethane panels). Oversize material travels over the deck surface to a designated discharge spout.
4. Protected Discharge: Sized fractions are discharged through sealed discharge spouts designed to minimize dust emission and spillage.

Escopo de aplicação & Limitações:
Escopo: Ideal for primary screening of hot or cold coke (coque de nozes, brisa) in coke plants, siderúrgicas, e instalações de produção de ânodos. Capable of handling feed sizes typically from 080mm.
Limitações: Not designed as a replacement for finewet screening or dewatering applications. Maximum efficiency is achieved with controlled feed rates as per designed capacity.
