2. GAMBARAN KESELURUHAN PRODUK

Yang moden Loji Penghancur Bijih Besi is a engineered system of primary, sekunder, and sometimes tertiary stationary crushers, skrin, and material handling equipment designed to reduce runofmine (ROM) iron ore to a conveyable size for further processing. The operational workflow is critical for efficiency:

1. Penghancuran utama: bijih ROM (sehingga ketulan 1.5m) dikurangkan kepada <250mm typically using a gyratory or jaw crusher selected for high capacity and ability to handle occasional tramp metal.
2. Menghancurkan sekunder: Further size reduction to <75mm via cone crushers configured for abrasive service, selalunya dalam litar tertutup dengan skrin.
3. Pemeriksaan & Penghancuran tertiari: Screening separates material to specification; oversize may be sent to tertiary cone crushers for precise product sizing critical for beneficiation.

Skop Permohonan: Designed for magnetite, hematit, and other ironbearing minerals in both greenfield installations and retrofit upgrades.
Had Utama: Feed size must be within crusher design limits; highly sticky or clayrich ores may require prescreening/scalping. System output is ultimately governed by the bottleneck stage.
