What is a wet mill? What is its main use?

Wet mill, also known as wet mill, is a kind of grinding equipment developed on the basis of traditional stone mill. It is mainly used for grinding various metal minerals (such as gold, silver, lead, zinc, molybdenum, iron, copper, etc.) and non-metallic minerals, further grinding the crushed materials, so that the useful minerals and chalcopyrite minerals are dissociated, and conditions are created for the subsequent sorting operations (such as flotation, re-election, magnetic separation, etc.). Wet mill is especially suitable for small and medium-sized mineral processing plant.

How does a wet pan mill work?

The wet pan mill mainly consists of a power unit (motor, reducer), frame, water basin, grinding wheel, and grinding pan, adopting wheel-driven grinding.

How does the grinding wheel rotate?

The motor drives the vertical main shaft through a reducer.
The vertical main shaft transmits torque to the horizontal shaft above.
Pull rods at both ends of the horizontal shaft drive the grinding wheels.
The grinding wheels both revolve around the vertical main shaft (revolution) and rotate around their own axes (rotation). This dual motion creates crushing and kneading effects on materials.

How is the grinding pan fixed?

The grinding pan is fixed to the frame and remains stationary.

How are minerals crushed and ground?

In summary, the wet pan mill combines the grinding wheels’ dual motion with a fixed pan to pulverize minerals through pressure and friction, offering simple structure, easy operation, and low investment costs.

Minerals and water are fed into the water basin.

The grinding wheels apply pressure through their weight during revolution and rotation.

Intense friction between grinding wheels and pan subjects minerals to repeated compression, kneading, and grinding.

Scrapers on the grinding pan continuously push materials under the wheels for uniform processing.

Properly ground minerals discharge with water flow, completing the grinding process.

Advantages of wet mill:

Simple structure, easy to operate and maintain: The structure of wet mill is relatively simple, easy to install, operate and maintain.
Small investment, quick results: Compared with other grinding equipment such as ball mills, wet mills have lower investment costs and are suitable for small and medium-sized beneficiation plants.
Good grinding effect: the grinding and rubbing action of the mill wheel can make the minerals fully dissociated from the monomer, and improve the effect of beneficiation.
Wide scope of application: it can be used for grinding of many kinds of metal and non-metal minerals.
Energy saving: Compared with other grinding equipment, the energy consumption of wet mill is relatively low.
Uniformity of mixing: Combined with the function of mixing and stirring to make slurry, so that the slurry concentration and other grinding indexes are stable.
Finished product quality: high density, good strength.
Full utilization of resources: Tailings can be recovered, so that effective resources can be fully utilized.
Stable operation: can strictly control the grading size, avoiding the phenomenon of over-crushing or uneven size of minerals.

How to choose the right wet mill?

Mineral properties:

Ore hardness: Harder ores require a wet mill with more wear-resistant wheels and discs and higher power.
Ore particle size: The feed size and desired product fineness determine the size and type of wet mill. Generally, the smaller the feed size, the smaller the required mill wheel diameter.
Mineral Composition: Certain minerals may be corrosive, requiring the selection of a wet mill made of corrosion-resistant material.

Production scale:

Processing capacity: According to the daily processing capacity or hourly processing capacity of the mineral processing plant to choose the appropriate specifications of the wet mill. Small size can be selected for small processing plant, while large size or multiple combinations are required for large processing plant.
Continuity: If continuous production is required, consider selecting a wet mill capable of continuous feeding and discharging.

Economic factors:

Equipment investment: The price of different models and specifications of wet mills varies greatly, and needs to be selected according to the budget.
Running cost: Consider the energy consumption, frequency of replacement of wearing parts and maintenance cost of the wet mill.

What are the main factors affecting shaking table separation?

Answer: Key factors influencing separation include the table’s motion (stroke and frequency), water volume and slope, feed rate and concentration, and the feed material’s particle size and shape. Proper adjustment of these factors is critical for efficient separation. The table’s longitudinal and transverse slopes must be precisely controlled. The feed concentration should also be appropriate, typically 20-30% for coarse minerals and 15-25% for fine minerals.

How do I operate and maintain a shaking table?

Answer: Operation involves observing the bed surface and adjusting the slope, water flow, and feed rate. Regular maintenance includes checking for loose parts, lubricating moving components, inspecting for wear, and cleaning the table surface. Preventative maintenance should be performed regularly, with intervals ranging from every month to once a year.

What are the common problems, and how do you troubleshoot them?

Answer: Common issues can include table shaking or choppy cuts, uneven material distribution, or poor separation. Troubleshooting may involve checking for loose bolts, damaged springs, or misalignment, adjusting belt tension, inspecting electrical components, and ensuring proper lubrication. If there’s unusual noise, identify the source and eliminate the problem.

What are the advantages and disadvantages of using a shaking table compared to other gravity separation methods?

Answer:
Advantages: Shaking tables offer high enrichment ratios, are relatively simple to operate, and produce visible separation zones, allowing for easy adjustment and monitoring. They are suitable for a wide range of particle sizes and densities.
Disadvantages: They typically have lower throughput capacity compared to some other methods like jigs or spirals. They also require a relatively large footprint and consume a significant amount of water.

How do I choose the right size and type of shaking table for my application?

Answer: The selection depends on the material being processed, the desired throughput, and the particle size range. Factors to consider include the deck area, stroke length, and riffle design. Consulting with a manufacturer or expert is recommended to determine the optimal configuration.
