The multi-shaft mill is a vertical structure stirred mill. It demonstrates more outstanding advantages than traditional ball mills in the fields of fine and ultra-fine grinding due to its efficient, energy-saving, and ultra-fine friction grinding method, providing a high-quality equipment choice for efficient and energy-saving grinding.

The multi-shaft mill has been widely used in the metal and non-metal mining industries, such as regrinding and fine grinding operations of minerals including iron ore, copper ore, copper-nickel ore, lead-zinc ore, molybdenum ore, gold concentrate, zinc ore, nickel ore, gold ore, rare earth ore, alumina, calcium carbonate, graphite, fluorite, tailings, talc, and others.

Composition and Working Principle of the Multi-Shaft Mill ：

1. Equipment Composition

The multi-shaft mill has a compact structure, mainly composed of a drive motor, reducer, multi-shaft spiral agitator, grinding chamber, frame, and lubrication system. Compared to traditional single-shaft stirred mills, the multi-shaft design further improves grinding efficiency and material dispersion uniformity.

2. Working Principle

It uses the self-weight of the material inside the tower and the centrifugal force generated by the rotation of the multi-shaft spiral blades to achieve continuous grinding of the material. The specific process is as follows:

Material enters from the top of the multi-shaft mill and moves downward under its own gravity;

Inside the equipment, the multi-shaft spiral blades rotate at high speed, forming a strong centrifugal force field that evenly disperses the material to all corners of the grinding chamber;

The dispersed material violently collides and rubs with the grinding media (such as steel balls or steel segments). Under the combined action of multi-shaft stirring and grinding media, the material is continuously impacted and sheared to achieve refinement;

The refined material has an increased specific surface area and improved uniformity, facilitating subsequent processing and is often used as the final grinding step.

Seven Major Advantages of the Multi-Shaft Mill ：

1. Uniform and efficient crushing: Through the built-in multi-shaft spiral agitator, the grinding media is driven to form a high-speed rotating flow field, generating stronger shear force and grinding action, allowing the material to be quickly and evenly crushed within a limited space, greatly improving grinding efficiency.

2. Adjustable coarse and fine grinding: Can meet coarse or ultra-fine grinding requirements by adjusting operating parameters, especially capable of stably producing ultra-fine powders with d97 < 10μm, suitable for high-tech fields requiring high-quality powders.

3. Energy saving: Outstanding performance in energy saving and emission reduction, with unit energy consumption reduced by 30%~50% compared to traditional ball mills, and energy consumption far lower than traditional equipment at the same production volume.

4. Low noise: Lower noise during operation, improving the working environment and reducing noise pollution; also adopts a compact vertical structure, significantly reducing the footprint.

5. More energy-efficient grinding of hard ores: When processing high-hardness materials, grinding is dominant. Compared to the impact crushing method of ball mills, it can more evenly crush hard ores while reducing media wear by more than 40%.

6. Grinding of wet minerals: Material moisture does not require pre-drying and can be processed directly, avoiding the problem of poor crushing effect caused by high material stickiness in traditional vertical mills.

7. Capable of fine classification: Equipped with a closed-loop circulation system, achieving a classification efficiency of over 98% for crushed materials, greatly reducing over-grinding phenomena and improving product quality and uniformity.
