2. GAMBARAN KESELURUHAN PRODUK

An loji penghancur bijih besi is a engineered system of primary, sekunder, and often tertiary stationary crushers, skrin, and material handling conveyors designed specifically for the highvolume reduction of runofmine (ROM) hematite or magnetite ore.

Aliran Kerja Operasi:
1. Penghancuran utama: bijih ROM (sehingga 1.5m) dikurangkan kepada <250mm typically using a gyratory or jaw crusher built for high throughput and abrasive service.
2. Menghancurkan sekunder: Bahan dikurangkan lagi kepada <75mm via cone crushers configured for heavyduty crushing pressure.
3. Pemeriksaan & Penghancuran tertiari: Screens classify material; onspec product is sent to stockpile, while oversize is recirculated through tertiary cone crushers for closedcircuit operation.
4. Pengendalian bahan: A network of heavyduty conveyors transfers material between stages.

Skop Permohonan: Designed for largescale mining operations processing >5 juta tan setahun (Mtpa) of abrasive iron ore.
Batasan: Not suitable for smallscale or pilot operations under 1 Mtpa due to capital intensity. Requires stable feed consistency from upstream mining operations for optimal performance.
