1. PEMBUKAAN PAINPOINT DRIVEN

Kos operasi yang semakin meningkat dan masa henti yang tidak menentu menghakis margin pemprosesan bijih besi anda? Plant managers and engineering contractors face persistent challenges in primary crushing that directly impact the entire downstream circuit. Titik kesakitan biasa termasuk:
Masa Hentian Tidak Dirancang yang Berlebihan: Frequent liner changes and unexpected mechanical failures in the primary station halt the entire feed line, menelan belanja beribu-ribu sejam dalam pengeluaran yang hilang.
Kos Penyelenggaraan Tinggi & Intensiti Buruh: Penghancur rahang tradisional memerlukan kerap, laborintensive adjustments and part replacements, driving up both OPEX and safety exposure for maintenance crews.
Pengurangan Saiz Suapan Tidak Konsisten: Fluctuations in ore hardness and feed size can cause chokefeeding or poor nip angles, leading to throughput bottlenecks and inefficient downstream grinding.
Degradasi Bahagian Pakai Pantas: Abrasive silica content in iron ore accelerates wear on crushing surfaces, resulting in premature liner failure and compromised product gradation.

Is your current primary crushing solution equipped to handle variable ore characteristics while maintaining throughput targets and controlling cost per tonne? The efficiency of your entire plant depends on the reliability of this first critical size reduction stage.

2. GAMBARAN KESELURUHAN PRODUK

The Iron Ore Primary Crushing Plant is a heavyduty, stationary crushing system engineered for the first stage of size reduction in mineral processing operations. Ia direka bentuk untuk menerima runofmine (ROM) iron ore directly from the mine face and reduce it to a conveyable size for secondary crushing or stockpiling.

Aliran Kerja Operasi:
1. ROM iron ore is dumped into a rugged vibrating grizzly feeder (VGFF VGF), which scalps off fine material and directs oversize to the crusher.
2. Oversize material is fed into a highcapacity jaw crusher, di mana ia dimampatkan antara plat rahang tetap dan bergerak.
3. Pelepasan bahan hancur ke penghantar produk utama untuk diangkut ke peringkat pemprosesan seterusnya.
4. The integrated VGF bypass directs natural fines onto the same conveyor, optimizing overall system efficiency.

Skop Permohonan & Batasan:
This plant is optimized for hightonnage processing of abrasive magnetite or hematite ores with compressive strengths typical of iron deposits. It is designed as a primary station only; subsequent crushing or grinding stages are required to achieve mill feed specifications. Sitespecific geotechnical assessments for foundation support are required prior to installation.
