Wet Pan Mill

Product Introduction

A Wet Pan Mill, also known as a Wet Pan Gold Mill, Gold Grinding Mill, Chilean Mill, or Gold Amalgamation Pan Mill, is a popular grinding machine widely used in small and medium-scale gold mining operations, especially in Africa, South America, and Southeast Asia.

The Wet Pan Mill is designed for wet grinding of gold ores and other mineral materials, combining grinding, crushing, and mixing functions in a single machine. Compared with traditional ball mills, the wet pan mill offers lower investment cost, easier operation, and excellent grinding performance, making it an ideal cost-effective alternative to ball mill equipment for many small gold processing plants.

This equipment is especially suitable for processing rock gold, alluvial gold concentrate, quartz gold ore, iron ore, copper ore, manganese ore, and other mineral materials. Due to its high grinding efficiency and strong adaptability, it has become one of the most widely used gold ore grinding machines in countries such as Sudan, Zimbabwe, Ghana, Tanzania, South Africa, Peru, Colombia, Brazil, and Indonesia.

The grinding process adopts a wet method, where ore is continuously crushed and ground between the manganese steel grinding rollers and grinding base plate. The fine particles produced after grinding can be further processed by gravity separation, flotation, or gold amalgamation methods.

Working Principle of Wet Pan Mill

The Wet Pan Mill mainly consists of a grinding roller, grinding basin, transmission system, frame, motor/diesel engine, and water feeding system.

During operation, the motor drives the central shaft, causing the heavy grinding rollers to rotate around the basin. The ore material is repeatedly pressed, crushed, and ground under the heavy pressure of the rollers.

At the same time, water is added into the grinding basin to form a slurry. The continuous rolling and mixing action improves mineral liberation, allowing gold particles and valuable minerals to separate effectively from the gangue.

Compared with dry grinding equipment, wet grinding provides:

• Better mineral liberation efficiency
• Lower dust generation
• Higher recovery rate for fine gold particles
• Improved grinding uniformity

For gold processing plants using amalgamation or gravity separation, the Wet Pan Mill is often the preferred choice because it can achieve the required grinding fineness with simple operation and maintenance.

Applications of Wet Pan Mill

Gold Mining & Mineral Processing

The primary application of the Wet Pan Mill is gold ore grinding. It is widely used in small-scale and artisanal gold mining plants where operators require reliable and economical grinding equipment.

Typical applications include:

• Rock gold processing plants
• Small and medium gold mines
• Gold amalgamation plants
• Gravity gold recovery systems
• Quartz vein gold processing
• Alluvial gold concentrate regrinding

The machine helps improve gold recovery by grinding ore into fine particles and releasing gold from surrounding minerals.

Alternative Grinding Solution to Ball Mill

For many small mining projects, a complete ball mill system requires higher investment, complex installation, and more maintenance costs.

The Wet Pan Mill provides a practical alternative with advantages including:

• Lower equipment investment
• Simple installation and operation
• Less auxiliary equipment required
• Suitable for remote mining areas
• Lower energy consumption

Therefore, many African and South American miners choose Wet Pan Mill as a low-cost gold ore grinding machine for starting or expanding mining operations.
