Kapasiti Tinggi, HighAvailability Iron Ore Crushing Plant for Maximum Tonnage and ROI

1. PEMBUKAAN PAINPOINT DRIVEN

Are escalating operational costs and unpredictable availability eroding your iron ore processing margins? Plant managers and engineering contractors consistently face a set of critical challenges that directly impact profitability:

Masa Henti Tidak Berjadual: Frequent mechanical failures in primary crushing stages can halt entire processing lines, costing thousands per hour in lost production and creating costly bottlenecks.
Saiz Produk Tidak Konsisten: Poorly controlled fragmentation from the primary crusher increases load on downstream secondary and tertiary circuits, raising energy consumption by 1525% and accelerating wear on conveyors and screening decks.
Kos Bahagian Haus Berlebihan: Bijih besi yang kasar, especially hematite with high silica content, can degrade manganese steel crusher liners in weeks, leading to high replacement costs, laborintensive changes, and safety risks during maintenance.
Konfigurasi Loji Tegar: Fixed crushing plants cannot adapt to variable feed sizes or changing product specifications, limiting operational flexibility and the ability to capitalize on different market segments.
Intensiti Tenaga Tinggi: Inefficient crushing chambers and drives consume excessive power per ton of material processed, menjadikan tenaga sebagai perbelanjaan operasi ketiga teratas.

How do you achieve reliable throughput of +2,500 TPH while controlling the total cost of ownership? What plant design ensures consistent product sizing to optimize downstream ball mill efficiency? The solution lies in a purposeengineered iron ore crushing plant.

2. GAMBARAN KESELURUHAN PRODUK

This iron ore crushing plant is a stationary, hardrock crushing system engineered for primary, sekunder, dan pengurangan tertier bijih magnetit dan hematit. It is designed for largescale mining operations with a focus on longevity, kemudahan penyelenggaraan, and process control.

Aliran Kerja Operasi:
1. Lambakan Utama & PraSkrining: Runofmine (ROM) ore is dumped into a rugged grizzly feeder, removing sub100mm fines to bypass the primary crusher, increasing circuit efficiency.
2. Menghancurkan Rahang Utama: A heavyduty jaw crusher reduces ROM ore from up to 1.5m lumps to a nominal 250mm product.
3. Sekunder & Tertiary Cone Crushing: A closedcircuit system with cone crushers and vibrating screens further reduces material to the target product size (typically 32mm for direct feed or 12mm for beneficiation circuits).
4. Product Stockpiling: Correctly sized crushed ore is conveyed to designated stockpiles via heavyduty conveyor systems with metal detection and tramp iron removal.

Skop Permohonan & Batasan:
Skop: Ideal for greenfield installations or major expansions requiring throughput from 1,000 ke atas 3,000 Tph. Suitable for both blasted and direct shovelloaded feed.
Batasan: Not designed for sticky claybound ores without prior washing/scalping. Maximum feed size is constrained by primary crusher model selection.
