A ball mill is a highly efficient ultrafine crushing device. In recent years, there have been some encouraging advancements in the research and production of vibration mills suitable for ultrafine crushing of non-metallic minerals. A vibration mill mainly consists of a frame, exciter, grinding jar, electrical control system, cooling system, and grinding media. The high-frequency circular vibration generated by the exciter causes the grinding media inside the mill to undergo a high-speed self-rotation combined with low-speed revolution, resulting in an intense rotational impact motion. This composite motion forms a strong impact crushing and grinding effect on the material, generally capable of grinding materials to micron levels with a narrow particle size distribution. It has wide applications in ceramics, non-metallic minerals, pigments, electronics, chemicals, metallurgy, construction materials, new materials, food, and pharmaceuticals.
For example, a certain unit in Yantai developed an ultrafine vibration mill used for ultrafine processing of graphite. With feed particle size of -100 mesh, after 20 hours of grinding (www.xykjc.com), 95% of the product was less than 4um, achieving a median particle size of 0.49um. Another example is a certain unit in Xi'an that developed a frequency converter multifunctional vibration ball mill. With feed particle size of -3mm, the product fineness (specific surface area) can reach 1022cm²/g. However, overall, there is still a certain gap compared to countries like Japan and Germany, and further efforts are needed in many aspects. Regarding the existing issues, it is recommended to conduct more in-depth research in the following areas:
(1) **Equipment performance research:**
- ① Relationship between machine vibration intensity, average material retention time, and product fineness.
- ② Relationship between specific energy consumption and product fineness.
- When vibration parameters remain unchanged, the relationship between cylinder size and specific energy consumption.
(2) **In terms of ball mill frame design**, optimize the design method to minimize the weight of the machine.
(3) **In terms of material quality**, primarily research the material and treatment process of the inner lining of the cylinder (www.xykjc.com) so that the working mechanism can withstand high vibration and impact loads while having strong wear resistance.
(4) **Research on supporting equipment** mainly solves continuous and uniform feeding equipment as well as reduces dust problems.
(5) **In the selection of grinding media**, study the reasonable choice of media and its non-iron wear-resistant properties (for grinding materials that require avoidance of iron contamination) to enhance the economic benefits of the equipment and expand its application range.
(6) **In labor protection**, study soundproofing or noise-canceling devices to control noise below 85dB.
(7) **In enhancing the process research**, study the relationship between grinding media, material quantity, and moisture content, as well as suitable super-low temperature grinding for tough and heat-sensitive materials. Use grinding aids that can reduce particle hardness and promote crack expansion.
