1. ABERTURA ACIONADA POR PAINPOINT

A gestão da escória é um gargalo persistente com custos tangíveis. Você está enfrentando esses desafios operacionais?
Taxa de transferência não confiável: Inconsistent feed size and hardness cause frequent jams in primary crushers, halting your entire processing line for hours.
Desgaste Excessivo & Custos de manutenção: The abrasive nature of slag rapidly degrades standard crushing components, leading to unscheduled downtime and a high costperton for replacement parts like liners and hammers.
Inefficient Liberation of Metallics: Incomplete crushing leaves valuable ferrous metals trapped within slag aggregates, resulting in direct revenue loss from unrecovered material.
Altos custos operacionais de mão de obra: Compensação manual, constant monitoring, and reactive maintenance demand significant labor hours that could be allocated elsewhere.
Dust and Noise Compliance Issues: Uncontrolled crushing operations generate excessive particulate matter and noise, creating environmental compliance risks and workplace hazards.

The core question for plant managers is: how do you transform this problematic byproduct into a consistent, profitable product stream while controlling operational expenses? The answer lies in a purposeengineered slag crusher plant.

2. VISÃO GERAL DO PRODUTO

A modern slag crusher plant is a turnkey processing system designed specifically for the size reduction and liberation of metallics from steel slag, blast furnace slag, and other industrial byproducts. It is not merely a collection of standard crushers but an integrated circuit engineered for abrasion resistance, tramp metal protection, and material flow management.

Fluxo de Trabalho Operacional:
1. Recebimento Primário & Pré-triagem: Slag feedstock is fed via loader or conveyor into a robust vibrating grizzly feeder. This initial stage removes fine material (030milímetros) para evitar esmagamento desnecessário, enhancing overall efficiency.
2. Redução de tamanho primário: Oversize material enters a heavyduty primary crusher—typically a jaw or impact type with special alloy liners—to break down large slabs and chunks into manageable pieces (aprox.. 150milímetros).
3. Magnetic Separation (First Pass): A suspended overhead magnetic separator extracts liberated ferrous metal immediately after primary crushing, protegendo equipamentos a jusante.
4. Secundário & Britagem Terciária: Material proceeds through secondary (cone ou impacto) and possibly tertiary crushers to achieve the final specified aggregate size (por exemplo, 020mm or 040mm).
5. Triagem Final & Recuperação de Metais: Crushed material is classified by vibrating screens into commercial fractions. A second magnetic drum separator ensures maximum metallic recovery from the final product before stockpiling.

Escopo de aplicação & Limitações:
Escopo: Ideal para usinas siderúrgicas integradas, pátios autônomos de processamento de escória, construction aggregate producers utilizing slag, and metal recovery specialists.
Limitações: Not designed for primary ore processing or extremely hard rock (por exemplo, granito). Feed size is typically limited by the primary crusher opening (commonly up to 8001000mm). Performance is contingent on proper feed control to prevent overloading.
