Content Body: Kilang Penghancur Bijih Besi Industri

1. PEMBUKAAN PAINPOINT DRIVEN

Is your current iron ore crushing circuit struggling to maintain a consistent P80 of 1012mm for downstream ball mill feed? Are you facing unplanned downtime exceeding 15% due to premature liner wear from high silica content (SiO₂ > 8%)? Many operations report that inefficient primary crushing alone adds $0.50–$1.20 per ton in energy costs, while poor reduction ratios force secondary and tertiary stages to run at 110% kapasiti, accelerating component fatigue.

Can your existing plant handle the shift from hematite to magnetite ore bodies without a complete reconfiguration? How much production are you losing to bridging and blockages in the jaw cavity during wet season operations? These are the operational bottlenecks that directly impact your cost per ton and overall plant availability.

2. GAMBARAN KESELURUHAN PRODUK

ini Kilang Penghancur Bijih Besi Industri adalah bersepadu sepenuhnya, modular crushing system designed specifically for hightonnage (1,000–6,000 TPH) iron ore processing. The operational workflow follows a proven fourstage reduction path:

1. Penghancuran Gyratory Primer: Runofmine (ROM) bijih (up to 1,500mm) is reduced to 200300mm using a heavyduty gyratory crusher with a spider bearing design for high eccentric throw.
2. Penghancuran Kon Sekunder: Ore is fed into a heavyduty cone crusher (mis., CH880 or equivalent) for secondary reduction to 5075mm, with a closedside setting (CSS) of 2540mm.
3. Tertiary HPGR (Gulungan Pengisar Tekanan Tinggi): The material passes through an HPGR unit for interparticle comminution, reducing it to 612mm, which significantly reduces ball mill work index (Wi) oleh 1525%.
4. Pemeriksaan & Recirculation: Multideck banana screens classify the product. Oversize material is recirculated to the tertiary crusher, while the final product is conveyed to the stockpile.

Skop Permohonan: Ideal for greenfield projects and brownfield expansions processing hard, bijih besi yang kasar (Indeks Kerja Bon 1422 kWj/t). Batasan: Not recommended for highclay content (>15%) lateritic ores without prewashing stages, as material handling issues may arise.

8. Soalan Lazim

S1: Can this plant handle ore with a high moisture content (812%)?
A: ya. The primary gyratory is designed with a steep nip angle and a spider arm configuration that prevents packing. For the HPGR, we recommend a feed moisture limit of 10% to avoid material slippage. Above this, a predrying or dewatering screen is advised.

S2: What is the typical payback period for the HPGR upgrade?
A: Based on field data from 12 installations, the payback period for the HPGR module (compared to a tertiary cone circuit) is typically 1422 bulan, driven by energy savings ($0.300.50/ton) and improved ball mill throughput.

S3: How does the plant perform with different ore types (magnetite vs. hematit)?
A: The plant is designed for variable feed. For magnetite, the HPGR can be operated at a higher specific pressing force (4.5 N/mm²) to achieve microcracking. For hematite, the focus is on reducing fines generation. The VFDs allow for realtime tuning.

S4: What is the lead time for a 4,000 loji TPH?
A: Current lead time is 1416 months from order to FOB port. This includes 8 months for fabrication, 2 months for preassembly, dan 4 months for shipping. Onsite installation typically takes 68 bulan.

S5: What is the warranty on the crusher mainshaft?
A: The mainshaft carries a 5year warranty against manufacturing defects, provided the crusher is operated within the specified power draw and CSS limits. Liner wear is excluded from the standard warranty.

S6: Can the plant be integrated with an existing SCADA system?
A: ya. The control system uses standard OPCUA and Modbus TCP/IP protocols. We provide a full data mapping document for integration with Rockwell, Siemens, or ABB DCS/SCADA platforms.

S7: What are the power requirements for a 3,000 loji TPH?
A: The total connected load is approximately 14,500 kw. The primary crusher motor is typically 1,200 kw, the HPGR motors are 2 x 2,800 kw, and the remaining load is for conveyors and screens. A 33 kV incoming supply is recommended.
