1. PEMBUKAAN PAINPOINT DRIVEN

Adakah anda menghadapi kesesakan yang berterusan dalam litar pemulihan emas anda? Inefficient primary crushing and grinding directly impact throughput, kadar pemulihan, dan kos operasi. Common challenges with conventional comminution include:

Masa Henti Operasi yang Tinggi: Frequent liner changes and unplanned maintenance on primary crushers halt your entire processing line, menelan belanja beribu-ribu sejam dalam pengeluaran yang hilang.
Inconsistent Feed Size for Milling: Poorly calibrated crushing leads to oversize material entering ball mills, reducing grinding efficiency and increasing power consumption per ton.
Penggunaan Tenaga Berlebihan: Inefficient size reduction technology can make comminution the single largest energy cost in your plant, menghakis margin keuntungan.
Kos Bahagian Pakai Tinggi: Agresif, unoptimized crushing mechanisms result in premature wear of mortars, mati, dan kasut, leading to high recurring spare parts expenses.
Limited Flexibility for Variable Ore Hardness: Fixedspeed systems struggle with fluctuations in feed material, causing either underprocessing or equipment overload.

Adakah operasi anda mencari yang mantap, proven solution to create a consistent, optimal feed for your gravity separation or leaching circuits while controlling capital and operational expenditure?

2. GAMBARAN KESELURUHAN PRODUK

The modern heavyduty stamp mill is a purposebuilt primary crushing system designed for the reliable reduction of goldbearing quartz ore and hard rock feed material. It serves as a critical first stage in mineral liberation, preparing ore for secondary milling or direct gravity concentration.

Aliran Kerja Operasi:
1. Pengenalan suapan: Runofmine (ROM) ore is fed into a sealed hopper, regulating flow onto the stamp shoe.
2. Cyclic Percussive Crushing: Setem berat yang diangkat secara mekanikal (camshaft or hydraulic) drop onto the ore bed contained within a hardened mortar box.
3. Klasifikasi saiz & Pelepasan: Bahan yang dihancurkan melalui plat skrin berlubang di dasar kotak mortar. The screen aperture defines the maximum product size.
4. Pulp Handling (Pilihan): Water can be introduced to create a slurry discharge for direct transport to subsequent wet processing stages.

Skop Permohonan & Batasan:
Sesuai Untuk: Primary crushing of quartz veins, hard rock gold ores, and sulphidebearing materials. Sesuai untuk operasi skala sederhana (50500 TPD), modular plant designs, dan kawasan dengan ketersediaan kuasa grid terhad.
Batasan: Not designed for fine grinding; product size is typically 10mm to 20mm. Less effective for clayrich or highly abrasive ores without modification. Requires firm foundation due to dynamic loads.
