1. PEMBUKAAN PAINPOINT DRIVEN

Managing a gold mining operation means confronting persistent challenges that directly erode profitability. When it comes to material handling and processing, common pain points include:
Masa Henti yang Tinggi daripada Tersumbat: Unprocessed oversize material and claybound aggregates can halt entire processing circuits, menelan belanja beribu-ribu sejam dalam pengeluaran yang hilang.
Inefficient Liberation of Gold: Inadequate scrubbing and breaking of ore leads to poor gold exposure, mengakibatkan pelaporan emas boleh diperoleh semula yang ketara kepada tailing.
Air Berlebihan & Penggunaan tenaga: Inefficient washing and screening processes inflate operational costs for water procurement, mengepam, and treatment.
Beban Penyelenggaraan Tinggi: Equipment not designed for abrasive feed materials suffers rapid wear on critical components, leading to frequent shutdowns and high parts replacement costs.
Suapan Tidak Konsisten kepada Proses Hiliran: Variable particle size distribution from primary processing creates instability in milling and gravity circuits, reducing overall recovery efficiency.

Are you seeking a solution to reduce circuit downtime, improve gold liberation rates, and lower your cost per ton processed?

2. GAMBARAN KESELURUHAN PRODUK: SCRUBBER / TROMMEL FOR GOLD BEARING ALLUVIAL & HARD ROCK ORE

A heavyduty scrubber or trommel is a core piece of premilling equipment designed for the aggressive preparation of goldbearing ore. Its function is to break down claybound aggregates, scrub deleterious materials from rock surfaces, and classify material by size to prepare an optimal feed for downstream concentration.

Aliran Kerja Operasi:
1. Pengenalan suapan: Runofmine (ROM) or alluvial ore is conveyed into the rotating drum section.
2. Menggosok Agresif & Pergeseran: Internal lifters cascade the material; the impact between rock particles and against reinforced scrubber bars breaks down clays and soft aggregates.
3. Saiz & Pengelasan: Semasa bahan bergerak melalui dram, bahan bersaiz kecil melalui apertur skrin (gendang) or grates (penyental).
4. Pemisahan Produk: Bersaiz besar (+10mm to +50mm, depending on screen selection) exits the drum discharge end for further crushing. The undersize slurry reports to vibrating screens or direct pump sumps for subsequent gold recovery processes.

Skop Permohonan: Ideal for alluvial/eluvial deposits with sticky clays, weathered saprolite ore, and hard rock ores requiring prewashing and classification before cyanidation or gravity circuits.

Batasan: Not a substitute for primary crushing of competent hard rock; feed size must be compatible with drum diameter. Water availability is a prerequisite for effective operation.
