Basic Overview The Trommel gold mining machine is a highly characteristic mobile gold extraction equipment designed for modern placer gold operations. It comes fully equipped with a reversible wet material hopper, grid screen, washing drum, and enrichment drum. With an advanced anti-spiral system, this machine ensures continuous operation while significantly increasing the gold recovery rate and reducing operational difficulty.

Key Performance Highlights:

• High Recovery Rate: Exceeds 92% for placer gold.

• Fine Recovery: Capable of recovering particles as fine as 300 mesh.

• Low Water Consumption: Minimal water usage; cleaning is only required at the end of the day or per batch.

Product Description & Working Process

1. Feeding: Material is fed into the “Wet Hopper” via an excavator. High-pressure water jets wash material into the inner desilting drum.

2. Screening: Stones larger than 5cm are separated. The inner drum breaks down clay and separates it from gravel and gold particles.

3. Enrichment: Materials smaller than 10mm enter the outer enrichment drum with an enrichment ratio of up to 100:1.

4. Final Extraction: The concentrated heavy sand enters the side cleaning chutes for secondary enrichment, allowing you to see gold dust directly at the end of the shift.
