Steel balls as traditional grinding media are prone to excessive fines generation and high energy consumption. Therefore, in light of this problem, the authors investigated another media—ceramic balls based on the output characteristics of fine particles. This study discusses the effect of ceramic balls on the change of the particle size distribution, zeroorder output characteristics, micro ...

The mill used in the study had inner dimensions of m diameter and m length and was divided into two compartments. The first 3 m of the mill was used as drying chamber, the remaining m was the grinding chamber. The mill operated at 70% of the critical speed. The ball load in the mill was 32% by volume, and 10030 mm balls were used.
