1. Ball mill tank: Generally, the weight of the four ball mill tanks (tank + ball + sample + auxiliary materials) should be basically the same to maintain stable operation, reduce noise caused by vibration, and extend the service life of the equipment. If the sample is insufficient, it can be used symmetrically (only two cans).
2. Sample: The diameter of the sample is usually less than 1 mm, the solid particles generally do not exceed 3 mm, and the soil allows 10 mm.
3. Loading: the maximum volume of loading (sample + ball + auxiliary materials) is two-thirds of the volume of the ball milling tank, and the remaining one-third is used as operating space.
4. Rotation speed: In order to obtain the best results, parameters such as the speed, milling time, ball distribution (a reasonable combination of large and small balls), sample size, number, and auxiliary materials should be selected appropriately. The speed is high, the efficiency is not necessarily high. At the beginning of grinding, the speed can be higher (acting to smash the sample), after grinding for a period of time (generally no more than 2 minutes), the speed can be lowered, so that the ball mill
higher efficiency. The efficiency of ball milling is determined by the matching of balls (large, small, more, less), the properties of the sample and whether the particle size, weight, speed, and operating mode are properly matched. In order to improve the grinding efficiency and prolong the service life of the ball mill, it is not necessary and should not be adjusted too high.
