Dry grinding means that after the ore has undergone a certain crushing operation in the ball mill, it will be taken out by the airflow drawn out of the barrel when it meets the requirements. The ball mill used in the dry grinding process is a dry ball mill. The dry ball mill does not need to add water during the production process .

Disadvantages of Dry Ball Mill. Grinding by dry means is inefficient. A large deposit shows small cracks during the grinding and kneading process. The gap becomes smaller and smaller due to the lack of material blocking the crack, which results in low grinding efficiency and slow material separation.

The changes in ion-exchange characteristics of synthetic mordenite ground by a planetary ball mill under dry conditions were investigated using radioisotopes of 137 Cs and 85 Sr as tracers. The self-diffusion of Cs + in the mordenite sample was facilitated in the initial stage of grinding, while it was leveled off for the further operation. The relative amount of Cs + immediately exchanged in ...

Mechanical ball mills. With mechanical ball mills, material is discharged mechanically through a discharging box. The material is usually further conveyed to a dynamic separator, which together with the mill forms a mechanical ball mill grinding plant. These grinding plants are used to comminute relatively dry materials to a very high fineness.
