The SD Dry Grinding Attritors can be operated in both continuous and batch processing applications. In the continuous operation, the material is fed into the vessel at the top. It then migrates through the agitating media bed where it is processed to a desired particle size and is discharged through metering bar grids at the bottom of the tank.
In addition, the loss in bioactivity could be associated with material grinding after the drying process in freeze-drying. The grinding process increased the possibility of contact between the powders and the air, resulting in an oxidation reaction leading to the deterioration of the active ingredients .
