1. PEMBUKAAN PAINPOINT DRIVEN

Managing an iron ore crushing circuit presents distinct and costly operational challenges. Plant managers and procurement specialists consistently face pressure to reduce costperton while maintaining stringent production targets. Adakah anda bertanding dengan:
Masa Henti Berlebihan untuk Penyelenggaraan: Frequent liner changes and unplanned repairs on primary crushers can halt your entire processing line, menelan belanja beribu-ribu sejam dalam pengeluaran yang hilang.
Throughput Tidak Diramalkan & Konsistensi Produk: Inefficient crushing stages or equipment mismatch lead to bottlenecks, reducing overall plant capacity and delivering inconsistent feed size to downstream grinding circuits, compromising recovery rates.
Kos Operasi Spiraling: High energy consumption per ton crushed, coupled with rapid wear part consumption in abrasive iron ore applications, secara langsung menghakis margin keuntungan.
Inflexibility to Ore Variability: Hard magnetite, weathered hematite, and sticky ore types each demand different crushing strategies. Rigid systems struggle to adapt, leading to blockages and reduced efficiency.

Memilih yang betul loji penghancur bijih besi bukan sekadar pembelian peralatan; it is a strategic decision impacting your mine's operational efficiency and longterm financial performance.

2. GAMBARAN KESELURUHAN PRODUK

The advanced modular loji penghancur bijih besi is a engineered system designed for highcapacity, reliable reduction of runofmine (ROM) iron ore to a consistent product size suitable for grinding or direct shipping. Its operational workflow is optimized for continuous mineral processing:

1. Penghancuran utama & Grizzly: ROM ore is fed into a robust primary jaw or gyratory crusher, often preceded by a vibrating grizzly feeder to bypass fine material and reduce primary chamber load.
2. Sekunder & Penghancuran tertiari: Crushed material is conveyed to secondary cone crushers for further size reduction, with tertiary cone crushers or highpressure grinding rolls (Hpgr) employed for final product shaping and fine generation.
3. Pemeriksaan & ClosedCircuit Control: Key screens separate product streams, with oversize material recirculated back to the appropriate crusher stage in a closed circuit, ensuring precise final product specification.

Skop Permohonan: Sesuai untuk projek perlombongan greenfield, pengembangan loji brownfield, and replacement of aging, litar penghancuran yang tidak cekap. Suitable for all major iron ore types (hematit, magnetite) with appropriate material specifications.

Batasan: System output is contingent on correct feed size distribution and ore characteristics (indeks lelasan, kandungan kelembapan). Maximum capacity is defined by the primary crusher opening and motor power.
