Wet Pan Mill for sale

Gold Mine Wet Pan Mill is a highly efficient, energy-saving and easy-to-operate equipment, especially suitable for gold extraction in small and medium-sized mines.

According to different structures, it has two types: double-roller and three-roller type. The most commonly used is double-roller type.

What is a Gold Mine Wet Pan Mill?

A Wet Pan Mill is a traditional and highly effective grinding and mixing machine. We also call it an edge runner mill or wheel mill. It uses two heavy, large-diameter steel wheels that rotate inside a circular steel pan. As they rotate, they crush and grind ore material into a fine slurry. Its simple design and powerful action make it a go-to piece of for miners all over the world. It is especially good at grinding ore after it has been through a jaw crusher.

Why Do You Need a Gold Mine Wet Pan Mill?

The biggest advantage is its high recovery rate for fine gold. A wet pan mill grinds material so fine that it liberates tiny gold particles trapped inside the rock. This makes it easier to capture the gold through methods like amalgamation or flotation.

Here are the main benefits for your operation:

• High Grinding Efficiency: It grinds and mixes at the same time, creating a uniform slurry.
• Excellent for Fine Gold: It can grind down to 200 mesh, exposing particles other machines miss.
• Cost-Effective: It has a low initial investment and lower power consumption compared to a ball mill.
• Simple to Operate: The design is straightforward, and daily operation does not require highly skilled labor.
• Handles Complex Ores: It works very well on ores that contain clay or other sticky materials.

Advantages of Gold Mine Pan Mill

A wet pan mill, also known as a gold grinding machine, is a traditional and highly effective tool for grinding ore. It operates by crushing and grinding material between heavy steel rollers and the base of a circular pan, mixed with water.

Its primary advantages include:

• Superior Fine Grinding: It excels at producing a very fine and uniform particle size. This repeated grinding and pressure action thoroughly liberates valuable minerals (like gold) from waste rock, which is critical for maximizing recovery rates.
• Combined Grinding and Mixing: The machine doesn’t just grind; it simultaneously and vigorously mixes the ore slurry. This is highly efficient for processes like gold amalgamation, as it combines two process steps into one.
• Low Cost and Simple Maintenance: With a robust, simple mechanical structure, wet pan mills have a low initial purchase price and affordable wear parts. They are easy to operate and repair, making them ideal for remote or small-scale operations with limited technical support.
• Ideal for Small-Scale Mining: Its low throughput, affordability, and effectiveness make it the perfect choice for artisanal miners and for processing tailings (waste piles) to recover residual precious metals.

Despite these benefits, its low capacity makes it unsuitable for large-scale industrial mining. Crucially, its historical association with highly toxic mercury amalgamation means that modern, safer recovery methods are now strongly recommended and often legally required.

• High output: It has high production efficiency and meets the needs of small and medium-sized mines.
• Easy to use and maintain: Simple structure, easy operation and low maintenance cost.

What is The Structure of Wet Pan Mill?

The main parts of the wet pan mill are the driving shaft, bearing seat, roller, speed reducer, motor, and so on. 

It has small investment, high output, low productioncost, good efficiency, and easy installation. 

The beauty of the wet pan mill is its simple and strong structure. There are no complex parts to break down. This makes it easy to maintain even in remote mining locations.The main components are:

• Grinding Pan: The heavy, stationary steel basin that holds the material.
• Grinding Wheels (Rollers): Two massive steel wheels that rotate inside the pan.
• Main Axle and Power System: A powerful electric motor connected to a gear reducer, which turns the main axle and the wheels.
• Scrapers: This is a part many people ignore, but it’s critical. Scrapers inside the pan continuously push the material back into the path of the wheels. If your scrapers are worn out, the mill becomes very inefficient. The scrapers are the brain of the operation.
• Frame: A robust steel structure that holds everything together.

Wet Pan Mill Working Principle

First, the motor transmits power to the reducer, then the central transmission shaft transmits it to the horizontal shaft, and finally the roller moves counterclockwise, and the materials in the mill are ground into fine particles.

While grinding the minerals,the fine particles of the dissociated minerals float to the upper surface and are discharged from the overflow discharge port; the coarse-grained minerals settle at the bottom and continue to be ground until the fineness reaches the standard.

How Does the Wet Pan Mill Work?

The process is a combination of crushing, grinding, and intense mixing. The heavy wheels provide the force. The water turns the material into a slurry.

But there is a big secret to how this machine really works. You are not just grinding; you are “activating” the material. The powerful rolling and shearing action forces water into every tiny crack in the ore. This breaks the material apart from the inside out and polishes the surface of the gold particles. This makes the gold very easy to capture with mercury or other recovery methods. It creates the perfect slurry for separation.

How Much Price of A Wet Pan Mill?

A new wet pan mill can cost anywhere from $3,000 to $25,000. The price depends on the size (model 1200 is common), the weight of the rollers, the quality of the materials used, and the brand.

But the machine’s price is only the start. The hidden cost that can hurt your profit is labor, especially during cleanup between batches. A mill with a poorly designed discharge gate can force your workers to manually shovel out hundreds of kilograms of sticky slurry. This downtime between batches adds up and kills your daily production. When you look at a mill, pay close attention to the discharge system. A good design will save you money every single day.

What are Spare Parts of Wet Pan Mill?

The main wear parts are the ones that are in direct contact with the ore. Because the grinding action is so intense, these parts are designed to be replaced.

The key spare parts you will need are:

• Roller Tires: The outer layer of the grinding wheels.
• Pan Liner: The floor of the grinding pan.

We make these parts from high-manganese steel. This is not regular steel. It has a special property called “work-hardening.” This means that as the steel gets impacted by the ore, its surface becomes harder and more resistant to wear. The machine literally gets tougher with use. Paying extra for high-manganese steel is the best investment you can make for the long-term life of your mill.

How Simple is the Installation and Daily Operation for Wet Pan Mill Machine?

The machine itself is simple, but the foundation is critical. Daily operation is straightforward. You load the material, add water, let it run, and then discharge the slurry.

However, you must get the installation right. A wet pan mill creates a powerful twisting force, also known as torsional force. It is constantly trying to twist the gearbox right off its mounting bolts. Your concrete foundation needs to be thick and heavily reinforced with rebar to handle this stress. A weak foundation will cause the machine to vibrate, which will quickly destroy the main bearings and gearbox.

What is the Process of Using Wet Pan Mill?

Following the correct process will give you the best results. Rushing the steps, especially adding water, will lead to a poor-quality slurry.Here is the professional way to operate the mill:

1. Dry Grinding: First, load your crushed ore into the pan. Run the mill for 5-10 minutes without any water. This breaks down the largest pieces.
2. Tempering (Adding Water): This is the most important step. Add water slowly while the mill is still running. Do not dump it all in at once. Let the material absorb the water evenly. A good operator knows the mix is ready by the sound of the mill.
3. Full Grinding Cycle: Let the machine run for the required time (this can be a few hours) until the material is a fine, uniform slurry.
4. Discharge: Open the discharge gate and collect the slurry for the next stage of gold recovery.

How Fine Can a Wet Pan Mill Grind to Maximize Gold Recovery?

A wet pan mill can typically grind ore down to 150-200 mesh (about 74 microns). This is very fine, like flour. Grinding to this size is essential because in many ores, the gold is locked inside the rock in tiny, microscopic particles. You have to grind the rock into a powder to “liberate” or expose the gold. Once the gold is exposed, it can easily stick to mercury or be captured by other separation methods. This ability to grind extremely fine is why the wet pan mill is so effective at increasing overall gold recovery rates.
