1. PEMBUKAAN PAINPOINT DRIVEN

Is your current iron ore crushing circuit delivering less than 85% masa beroperasi? Are you spending over $0.45 per ton on wear parts replacement due to high abrasion? For plant managers processing hematite or magnetite, the operational reality is often defined by three critical bottlenecks: premature mantle wear from feed material with a Bond Work Index exceeding 16 kWj/t, frequent downstream blockages caused by inconsistent product gradation, and escalating energy costs that consume 30% daripada belanjawan operasi anda.

These inefficiencies compound. A single unscheduled shutdown in a 2,000 tph plant can cost upwards of $50,000 sejam dalam pengeluaran yang hilang. Your engineering contractors need a solution that delivers consistent P80 of 1215mm while maintaining a power draw under 0.8 kWj/t. Can your current equipment guarantee this without requiring a secondary tertiary circuit overhaul?

2. GAMBARAN KESELURUHAN PRODUK

The Professional Iron Ore Crushing Plant adalah tugas berat, multistage processing system engineered specifically for highabrasion, highcompressivestrength iron ore (hingga 350 MPa). The operational workflow is designed for maximum liberation and minimal fines generation:

• Pengurangan utama: Bijih runofmine (sehingga 1,200mm) enters a heavyduty gyratory or jaw crusher, reducing feed to 150200mm.
• Menghancurkan sekunder: Cone crushers with a specialized eccentric throw (3850mm) process the material, targeting a 4060mm intermediate product.
• Penghancuran Tertiary/Quaternary: Highspeed (600800 Rpm) shorthead cone crushers or HPGRs (Gulungan Pengisar Tekanan Tinggi) reduce the ore to a final product of 1219mm for ball mill feed.
• Pemeriksaan & Recirculation: Multideck banana screens (6.1m x 2.4 m) classify material, recirculating oversize (+19mm) back to the tertiary crusher.
• Pemisahan Magnetik (Pilihan): Wet drum magnetic separators can be integrated postcrushing for preconcentration, reducing downstream milling load by 1520%.

Skop Permohonan: Best suited for mediumtohard iron ore (magnetite, hematit, specularite) with a moisture content below 8%. Batasan: Not recommended for highly claybound lateritic ores without a prewashing stage, as material packing can reduce throughput by 30%.

A: ya. The final product size (P80 of 1219mm) is compatible with most SAG mill feeds. We provide a transfer conveyor interface kit for seamless integration.

Q: What training is provided for plant operators?
A: A 5day onsite training program covers hydraulic system operation, pelarasan CSS, and predictive maintenance. A digital simulator is also provided for remote practice.

Q: Is the equipment compliant with ISO 14001 environmental standards?
A: ya. The dust suppression system meets EPA MACT standards for particulate matter. The closedloop water system allows for 90% kitar semula air, reducing fresh water consumption to 0.5 m³ per ton.
