The SDDry GrindingAttritors 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.
The optimalmillingoccurs at a critical speed.Ball millscan operate in either a wet ordrystate. Whilemillingwithout any added liquid is commonplace, adding water or other liquids can produce the finest particles and provide a ready-to-use dispersion at the same time.Grindingmedia comes in many shapes and types with each having its own specificpropertiesand advantages.
