1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

Managing slag is a critical but costly bottleneck in metal production and recycling operations. El procesamiento ineficiente afecta directamente sus resultados a través del desgaste del equipo., disposal expenses, and lost revenue from unrecovered metallics. ¿Estás enfrentando estos desafíos persistentes??

Altos costos de abrasión: Slag’s abrasive nature rapidly degrades standard crusher components, leading to frequent downtime for liner changes and rotor repairs, with replacement part costs cutting into operational budgets.
Metallic Recovery Inefficiency: 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.
Rendimiento poco confiable: Crushers not engineered for slag’s specific hardness and variability suffer from blockages, reduced capacity, and inconsistent output sizing, disrupting downstream material handling.
Regulatory Compliance Burden: Equipment that fails to meet stringent environmental directives, such as RoHS (Restricción de sustancias peligrosas), can restrict the marketability of your processed slag byproducts.

La pregunta central para los gerentes de planta es esta: ¿Cómo puedes lograr confiabilidad?, highvolume slag reduction while maximizing metal recovery, garantizar el cumplimiento medioambiental, and controlling total cost of ownership?

2. DESCRIPCIÓN GENERAL DEL PRODUCTO

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.

Flujo de trabajo operativo:
1. Alimentar & Pre-selección: 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. Reducción de tamaño primario: La trituradora de núcleos (normalmente una trituradora de mandíbulas o una trituradora de impacto) receives the material, applying high mechanical force to break down large slag chunks.
3. Separación de metales & Recuperación: Crushed material passes over an overhead magnetic separator (or eddy current separator for nonferrous metals) to extract liberated metallic fractions for recycling.
4. Trituración Secundaria & Apresto (Opcional): A secondary cone or impact crusher further reduces material to precise specifications, followed by screening decks to classify aggregate into defined fractions (p.ej., 05milímetros, 520milímetros).
5. Supresión de polvo & Control: Integrated water spray nozzles at transfer points and enclosed conveyor sections actively suppress dust emissions throughout the process.

Ámbito de aplicación & Limitaciones:
Alcance: Ideal para plantas siderúrgicas integradas, fundiciones, fundiciones de cobre/níquel, and metal recycling facilities processing blast furnace slag, robar golpe, or nonferrous slags. Output is a commercially viable construction aggregate.
Limitaciones: 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.
