Rotary trommel gold mining equipment

Product Overview

Our trommel screen gold washing equipment is a high-efficiency mobile alluvial gold mining solution, specially designed for river sand gold, placer gold, and clay-containing gold ore processing. Featuring adjustable rotation speed and customizable screen mesh, this gold trommel screen integrates high-pressure spraying, clay breaking, grading screening and gold pre-concentration in one unit. Built with wear-resistant high-manganese steel structure, it adapts to harsh outdoor mining environments. Available in small portable and large industrial models with 5–600 TPH processing capacity, it delivers high gold recovery rate, low energy consumption and easy mobile operation for small-scale and large-scale gold mining projects.

Product Brief Introduction

Reliable trommel screen gold mining equipment for alluvial and placer gold washing and screening. This mobile gold trommel adopts rotary screening and high-pressure water flushing technology to effectively separate gold ore from silt, clay, stones and impurities. It solves the problems of clay wrapping gold and low screening efficiency in traditional gold mining. With flexible customization of screen size, drum speed and processing capacity, the portable gold trommel screen supports free movement on mining sites, no complicated installation required. Durable, energy-saving and high recovery rate, it is the ideal core equipment for river gold panning, open-pit alluvial gold mining and small mineral processing projects worldwide.

Detailed Product Description

1. Product Introduction

The trommel screen gold washing equipment is professional placer gold processing machinery developed for alluvial gold, river sand gold, eluvial gold and mixed gold ore with clay and silt. Different from fixed screening equipment, our gold trommel screen adopts integrated modular design, combining feeding system, rotary screening system, high-pressure water spraying system, driving system and gold pre-separation system. It can complete ore clay breaking, impurity removal, particle grading and gold enrichment in one continuous operation.

Suitable for various complex mining scenarios including riverbed gold mining, desert placer gold mining, mountain slope alluvial gold mining and residual gold ore processing. It effectively improves the utilization rate of gold ore and solves the technical pain points of incomplete clay cleaning, low gold recovery and easy screen blockage in traditional gold washing equipment.

2. Core Features & Advantages

• Efficient Clay Breaking & Anti-blocking Design: Equipped with multi-group high-pressure spray nozzles and adjustable rotary drum structure. The rotating drum continuously stirs and flushes ore to break wrapped clay, effectively preventing screen mesh blockage and greatly improving screening efficiency.
• Customizable Processing Configuration: Drum rotation speed 8–12 RPM adjustable, screen mesh size 0.5–30mm customizable. Multiple models from 5TPH mini portable type to 600TPH large industrial type meet different mining scale demands.
• Durable & Harsh Environment Resistant: The main drum body adopts thickened carbon steel, and the screen mesh is made of high-manganese wear-resistant material, featuring anti-corrosion, anti-wear and impact resistance. It can work stably in muddy, dusty and humid outdoor mining environments for long-term service life.
• Mobile & Easy Operation: Integrated mobile chassis design, support trailer traction or crawler walking. No fixed foundation installation needed, convenient for site switching. Equipped with electric or diesel power system, flexible for off-grid mining areas.
• High Gold Recovery Rate: Precision grading screening + water flushing separation technology, effectively capture fine gold and coarse gold particles. Matched with sluice box gold collecting system, the overall gold recovery rate is significantly improved.
• Low Operation Cost: Optimized transmission structure, low energy consumption and low failure rate. Wearable parts are easy to disassemble and replace, reducing daily maintenance and operating costs.

3. Working Principle

After raw gold ore is fed into the trommel drum by loader or conveyor, the high-pressure water spray system first flushes and breaks clay agglomerates. With the slow rotation of the cylindrical trommel screen, materials are continuously turned and screened. Small-particle gold-bearing ore passes through the screen mesh and enters the next gold separation equipment for concentration and recovery. Large stones, gravel and waste impurities are discharged from the tail of the drum. The whole process realizes automatic continuous feeding, washing, screening and impurity removal, achieving efficient pre-enrichment of alluvial gold ore.

4. Application Scope

• Alluvial gold, river sand gold, placer gold mining and washing
• Gold ore with high clay, high silt and complex impurities
• Small-scale mobile gold mining and large-scale industrial gold washing projects
