Certificado de atacadista de mineração de cascalho de areia
1. ABERTURA ACIONADA POR PAINPOINT
Gerenciar uma operação de areia e cascalho significa enfrentar desafios persistentes, ineficiências dispendiosas. Você está enfrentando esses desafios comuns?
Material de alimentação inconsistente: Fluctuations in feedstock size and moisture content lead to frequent clogging, unplanned downtime for manual clearing, and suboptimal screening efficiency.
Altos custos de substituição de peças de desgaste: The abrasive nature of aggregate rapidly degrades screen panels, componentes de acionamento, e rolamentos, resulting in excessive spare parts inventory and labor costs for changes.
Separação ineficiente de multas: Inaccurate separation of fines from specification product leads to offspec material, wasted product in settling ponds, and potential revenue loss or customer rejection.
Excessive Vibration & Manutenção: Poorly balanced or lowquality vibrating screens transmit destructive forces to support structures and require constant bolt tightening, bearing checks, and foundational repairs.
Limitações de escalabilidade: Fixedscreen systems struggle to adapt to changing market demands for different aggregate specifications, forcing operators to choose between capital expenditure for new units or lost sales opportunities.
A questão central para os gerentes de fábrica é: how can you increase throughput of inspec material while directly reducing perton operating costs and maintenance hours? The answer lies in the core of your classification process: the industrial vibrating screen.
2. VISÃO GERAL DO PRODUTO: HEAVYDUTY VIBRATING SCREEN FOR SAND AND GRAVEL
Este equipamento é de alta capacidade, linear motion vibrating screen engineered specifically for the rigorous demands of sand and gravel mining. It is designed for the dry or wet screening of crushed stone, cascalho, areia, and recycled concrete aggregates.
Fluxo de Trabalho Operacional:
1. Introdução ao feed: Raw, crushed aggregate is conveyed onto the feed box of the vibrating screen, which evenly distributes material across the full width of the top deck.
2. Estratificação & Separação: A precisely calibrated dualvibrator motor system generates a linear throwing motion. Esta ação estratifica o material, lifting smaller particles to the top layer for contact with the screen media while conveying larger particles forward.
3. Classificação de tamanho: Particles smaller than the deck aperture fall through to subsequent decks or collection chutes. Oversize material travels across each deck surface toward the discharge end.
4. Product Stream Discharge: Correctly sized fractions are discharged from designated chutes—typically as oversize (por exemplo, +1”), middle product (por exemplo, 1/4” x 1”), e multas (por exemplo, areia) —onto separate conveyors for stockpiling.
Escopo de aplicação & Limitações:
Escopo: Ideal for primary sizing after crushing, final product classification (producing washed concrete sand, areia de pedreiro, lascas de cascalho), and dewatering washed aggregates. Effective for materials with a bulk density typical of aggregates (1.51.8 t/m³).
Limitações: Não projetado para pegajoso, highclaycontent materials without prescrubbing; maximum feed size is limited by deck aperture and impact resistance; performance is optimized within specified feed rate and moisture parameters.
