Jiangxi Mingxin Ball Mill takes sophisticated structure as the foundation and scientific grinding principle as the core. It has become a powerful grinding tool in solid waste recycling, ore processing and other fields, and built a solid core barrier for the grinding link in industrial production with its stable and high-efficiency performance.
The core structure of Mingxin Ball Mill consists of five key components: rotary cylinder, wear-resistant liner, grinding medium, transmission system, and feeding & discharging device. The cylinder is made of high-toughness steel, with wear-resistant manganese steel liners inlaid on the inner wall, which not only prevents scouring and wear, but also optimizes the movement track of grinding media; suitable steel balls/ceramic balls are carefully selected as grinding media and scientifically graded according to material characteristics; it is equipped with a high-efficiency transmission system to precisely control the rotating speed of the cylinder, and the feeding & discharging device realizes continuous and uniform material in and out to ensure uninterrupted production.
Its grinding principle relies on the triple effects of impact + grinding + extrusion. The cylinder rotates stably at 60%-85% of the critical speed, and centrifugal force and friction drive the grinding media and materials to lift synchronously. After reaching a specific height, the media fall under gravity to form a strong impact and crush large materials; at the same time, the rolling and sliding between the media and between the media and the liner continuously grind and extrude the materials to further refine the fine particles. From the feeding end to the discharging end, the materials are repeatedly acted on by the three forces, and finally ground to the required fineness, and accurately screened and discharged through the discharging device. Unqualified coarse materials can be returned for secondary grinding to achieve uniform and controllable finished product particle size.
