1. ABERTURA ACIONADA POR PAINPOINT

Managing slag is a critical but costly bottleneck in metal production and recycling operations. O processamento ineficiente afeta diretamente seus resultados financeiros através do desgaste do equipamento, disposal expenses, e perda de receita com metais não recuperados. Você está enfrentando esses desafios persistentes?

Altos custos de abrasão: A natureza abrasiva da escória degrada rapidamente os componentes padrão do britador, levando a tempos de inatividade frequentes para trocas de revestimento e reparos do rotor, with replacement part costs cutting into operational budgets.
Ineficiência de Recuperação Metálica: Inadequate crushing leaves valuable ferrous and nonferrous metals locked within slag aggregates, resulting in significant lost revenue from unrecovered material.
Dust and Emission Control Failures: Processing generates fine particulate matter, creating compliance risks with environmental health and safety (EHS) standards and exposing personnel to hazardous dust.
Taxa de transferência não confiável: Crushers not engineered for slag’s specific hardness and variability suffer from blockages, capacidade reduzida, and inconsistent output sizing, disrupting downstream material handling.
Regulatory Compliance Burden: Equipment that fails to meet stringent environmental directives, such as RoHS (Restrição de Substâncias Perigosas), can restrict the marketability of your processed slag byproducts.

A questão central para os gerentes de fábrica é esta: como você pode alcançar confiabilidade, highvolume slag reduction while maximizing metal recovery, garantindo a conformidade ambiental, and controlling total cost of ownership?

2. VISÃO GERAL DO PRODUTO

A RoHS compliant slag crusher plant is a purposeengineered stationary or semimobile system designed specifically for the primary and secondary crushing of metallurgical slag. It integrates robust size reduction technology with material handling and dust suppression systems to process slag into a calibrated aggregate while ensuring the final product adheres to RoHS substance restriction guidelines.

Fluxo de Trabalho Operacional:
1. Alimentar & Pré-triagem: Slag feedstock is loaded via excavator or conveyor into a hopper, often passing through a grizzly or scalping screen to remove oversize debris and direct fines away from the crusher.
2. Redução de tamanho primário: O triturador de núcleo (normalmente um britador de mandíbula ou britador de impacto) receives the material, applying high mechanical force to break down large slag chunks.
3. Separação de Metais & Recuperação: O material triturado passa por um separador magnético suspenso (or eddy current separator for nonferrous metals) to extract liberated metallic fractions for recycling.
4. Britagem Secundária & Dimensionamento (Opcional): A secondary cone or impact crusher further reduces material to precise specifications, followed by screening decks to classify aggregate into defined fractions (por exemplo, 05milímetros, 520milímetros).
5. Supressão de poeira & Controlar: Integrated water spray nozzles at transfer points and enclosed conveyor sections actively suppress dust emissions throughout the process.

Escopo de aplicação & Limitações:
Escopo: Ideal para usinas siderúrgicas integradas, fundições, fundições de cobre/níquel, and metal recycling facilities processing blast furnace slag, roubar golpe, ou escórias não ferrosas. Output is a commercially viable construction aggregate.
Limitações: Not designed for primary ore processing or extremely highmoisture materials without predrying. Plant throughput is fixed based on design; major capacity increases require system modification.
