1. PEMBUKAAN PAINPOINT DRIVEN

Are you facing persistent bottlenecks in your primary crushing and grinding circuit? The consistent, highvolume processing of goldbearing ore is fundamental to profitability, yet traditional comminution methods often introduce significant operational friction. Cabaran utama termasuk:

Masa Henti Berlebihan untuk Penyelenggaraan: Frequent liner changes and mechanical failures in complex grinding systems halt your entire processing line, menelan belanja beribu-ribu sejam dalam pengeluaran yang hilang.
Penggunaan Tenaga Tinggi setiap Tan: Inefficient crushing and grinding directly inflate your most variable cost—energy—eroding margins, especially in remote sites with expensive power.
Taburan Saiz Zarah Tidak Konsisten: Poorly controlled discharge from primary crushing leads to inefficient cyanidation or gravity recovery downstream, resulting in lower overall gold recovery rates.
Kos Bahagian Pakai Tinggi & Kerumitan: Systems with numerous moving parts and specialized components drive up ongoing spare part inventories and require highly skilled technicians for upkeep.
Had Kebolehskalaan: Modular or phased expansion can be prohibitively difficult with integrated, highcapacity milling systems.

2. GAMBARAN KESELURUHAN PRODUK

Yang moden Kilang Setem is a purposebuilt, heavyduty crushing apparatus designed for the reliable primary reduction of gold quartz ore. It operates on the proven principle of repetitive percussive crushing, delivering a consistent coarse to mediumfine feed ideal for secondary ball milling or direct cyanidation heap leach preparation.

Aliran Kerja Operasi:
1. Suapan: Runofmine (ROM) ore is fed into a sturdy mortar box via a regulated feed system.
2. Menghancurkan: Setem berat yang diangkat secara mekanikal (berat) are dropped onto the ore bed, memecahkan bahan melalui hentaman berulang.
3. Pengelasan & Pelepasan: Crushed material passes through a perforated screen at the mortar box's base; oversize material remains for further crushing while correctly sized pulp discharges.
4. Pengangkutan Slurry: The discharged slurry is conveyed to the next stage in your beneficiation process.

Skop Permohonan & Batasan:
Sesuai Untuk: Hard rock gold quartz veins, sulfide ores requiring preoxidation size reduction, and operations prioritizing mechanical simplicity and durability over ultrafine grinding.
Best Suited: For operations processing 50500 tan sehari, often as a primary crusher ahead of ball mills or in standalone setups for coarse gold recovery circuits.
Batasan: Not designed for producing ultrafine powder (<100 mesh) sebagai produk akhir; less energyefficient than some technologies for very soft ores; requires solid foundational support due to dynamic loads.
