The 4LQM-3SP4 high-performance ball mill can grind samples to the nanometer level in a short period of time. This instrument is suitable for grinding (dry or wet grinding) and mixing treatment of soft, medium hard, extremely hard, and brittle samples, and ensures that the grinding results are reproducible. Can be applied in pre-treatment of physical and chemical analysis, colloid grinding, preparation of new materials and mechanical alloys, etc.

working principle

When the instrument is started, the motor drives the common sun wheel to rotate, and the grinding tank located on the sun wheel rotates around its own axis. The direction of rotation of the grinding tank is exactly opposite to that of the sun wheel. The speed ratio between the sun gear and the grinding tank is generally 1: -2.3. When the grinding ball and the grinding tank operate together, they are affected by the superposition of self rotation bias force. Under this influence, the grinding ball releases a large amount of kinetic energy, and the sample is continuously impacted by the grinding ball, while generating a large amount of friction with the grinding inner wall, thus being highly crushed.

Main advantages
