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.

Quais são os principais factores que afectam a separação da mesa vibratória?
Resposta: Os principais factores que influenciam a separação incluem o movimento da mesa (curso e frequência), o volume e a inclinação da água, a taxa de alimentação e a concentração, bem como o tamanho e a forma das partículas do material de alimentação. O ajuste correto destes factores é fundamental para uma separação eficiente. As inclinações longitudinais e transversais da mesa devem ser controladas com precisão. A concentração de alimentação também deve ser adequada, normalmente 20-30% para minerais grosseiros e 15-25% para minerais finos.
Como operar e manter uma mesa vibratória?
Resposta: A operação envolve a observação da superfície da mesa e o ajuste da inclinação, do fluxo de água e da taxa de alimentação. A manutenção regular inclui a verificação de peças soltas, a lubrificação dos componentes móveis, a inspeção do desgaste e a limpeza da superfície da mesa. A manutenção preventiva deve ser efectuada regularmente, com intervalos que variam entre cada mês e uma vez por ano.
Quais são os problemas mais comuns e como resolvê-los?
Resposta: Os problemas mais comuns podem incluir a vibração da mesa ou cortes irregulares, distribuição desigual do material ou separação deficiente. A resolução de problemas pode envolver a verificação de parafusos soltos, molas danificadas ou desalinhamento, o ajuste da tensão da correia, a inspeção dos componentes eléctricos e a garantia de uma lubrificação adequada. Se houver um ruído invulgar, identifique a fonte e elimine o problema.
Quais são as vantagens e desvantagens da utilização de uma mesa de agitação em comparação com outros métodos de separação por gravidade?
Resposta:
Vantagens: As mesas vibratórias oferecem elevadas taxas de enriquecimento, são relativamente simples de operar e produzem zonas de separação visíveis, permitindo um fácil ajuste e monitorização. São adequadas para uma vasta gama de tamanhos e densidades de partículas.
Desvantagens: Normalmente, têm uma capacidade de produção inferior à de outros métodos, como os jigues ou as espirais. Também requerem uma área relativamente grande e consomem uma quantidade significativa de água.
Como é que escolho o tamanho e o tipo certo de mesa vibratória para a minha aplicação?
Resposta: A seleção depende do material a ser processado, do rendimento desejado e da gama de tamanhos de partículas. Os factores a considerar incluem a área da plataforma, o comprimento do curso e o design do riffle. Recomenda-se a consulta de um fabricante ou especialista para determinar a configuração ideal.
