Overview of Wet Grinding Mill: The Multifunctional Tool for Gold Ore Processing
The wet grinding mill, also known as a wet pan mill or gold ore mill, is a comprehensive piece of equipment that combines crushing, grinding, mixing, and separation functions. It is primarily used for the fine grinding of ores of non-ferrous metals such as gold, silver, lead, and zinc, and is particularly suitable for mining areas with limited water, electricity, or investment budgets.
Its working principle is simple and efficient: an electric motor drives heavy grinding rollers through a transmission device, which roll and press the ore on a circular grinding plate. During the grinding process, water is continuously added to form a slurry, which not only prevents dust from flying but also facilitates the separation of liberated gold particles from other minerals, creating optimal conditions for subsequent amalgamation, cyanidation, or gravity separation.

Why Choose a Wet Grinding Mill? Analysis of its Core Advantages
In our twenty years of equipment manufacturing and service, we have witnessed the popularity of the wet grinding mill due to its irreplaceable advantages:
Low Investment Cost and Economical Operation
Compared to large grinding equipment such as ball mills, wet grinding mills have lower purchase costs, simpler installation requirements, and lower power consumption, significantly reducing initial investment and long-term operating costs, making them ideal for small and medium-sized mines or startups.
Multi-functional and Streamlined Process
One piece of equipment can complete the process from crushing to fine grinding and preliminary separation. Its edge design usually features a discharge port, allowing heavier gold particles to easily settle and be collected through a specific channel during the grinding process, achieving partial gold recovery in advance and improving the overall recovery rate.
Robust Structure, Strong Adaptability
The equipment features a compact structure, and its main components, such as the grinding disc and grinding rollers, are made of high-chromium alloy or wear-resistant steel, ensuring durability. It has relatively lenient requirements for ore moisture content and feed particle size, adapting to various complex mining environments.
Simple Operation, Easy Maintenance
The mechanical structure is simple and intuitive, making it easy for operators to learn and use. It requires minimal daily maintenance, resulting in low maintenance costs and maintaining a high equipment operating rate even in remote areas.

Success Story: The Actual Performance of the Wet Grinding Mill
In a small-to-medium-sized gold mine project in Tanzania, Africa, the client faced challenges of unstable power supply and limited investment. We recommended and configured two 1500-type wet grinding mills, forming a simple grinding-amalgamation-shaking table gravity separation process.
• Before application: The ore was simply crushed and then directly cyanided, resulting in a gold recovery rate of only 65%-70%, with high reagent consumption.
• After application: The wet grinding mill ground the ore to over 80% passing -200 mesh, ensuring sufficient gold liberation. After pretreatment with this equipment, combined with the subsequent process, the total gold recovery rate increased to over 88%. The client expressed high satisfaction with the stable output particle size, low failure rate, and the improved efficiency brought to the entire production line.
Equipment Optimization and Related Recommendations
To maximize the efficiency of the wet grinding mill, we usually recommend the following equipment to form an efficient production line:
1. Jaw Crusher: As a primary crushing device, it crushes large pieces of ore to the ideal feed particle size for the small wet grinding mill (generally less than 30mm), reducing the burden on the wet grinding mill and increasing overall processing capacity.
2. Vibrating Feeder: Ensures uniform and continuous feeding to the wet grinding mill, avoiding machine idling or overloading, which is crucial for achieving stable grinding fineness.
3. Centrifugal Gold Separator/Shaking Table: As a subsequent fine separation device, it further recovers fine gold particles from the slurry discharged from the wet grinding mill, forming an efficient and low-cost gravity gold separation circuit.
Frequently Asked Questions (FAQ)
Q1: What are the main differences between a wet grinding mill and a ball mill?
A1: Wet grinding mills combine crushing, grinding, and preliminary separation functions, offering lower investment and energy consumption, making them suitable for small to medium-scale projects focused on cost-effectiveness. Ball mills have higher pure grinding efficiency, larger processing capacity, and produce finer particle sizes, but their systems are more complex and require higher investment, making them more suitable for large-scale modern processing plants. The two can often be used in combination depending on the project stage and scale.
Q2: What is the lifespan of the grinding rollers and grinding discs? Do they need frequent replacement?
A2: This depends on the abrasiveness of the ore. Our equipment uses special wear-resistant steel, and the lifespan of the core wear parts is typically 6-12 months when grinding medium-hardness gold ore. Even feeding and preventing metal foreign objects from entering the mill can effectively extend the service life. The replacement process is relatively simple and quick.
Q3: Can wet grinding mills process sticky ores with high clay content?
A3: Yes, they can, but the process needs to be adjusted. For sticky ores, we recommend appropriately increasing the grinding concentration or adding a certain proportion of coarse-grained ore to the feed to improve grinding conditions. In terms of equipment structure, we can also provide targeted scraper designs to prevent mud adhesion.
