The amount of grinding media of the sand mill

- Jan 20, 2021-

The amount of grinding media used by the sand mill is related to the viscosity of the slurry to be ground, and the temperature of the grinding slurry. Therefore, these factors must be considered when determining the amount of grinding media. The general principle is that when the viscosity of the slurry is high, the amount of grinding media should be less, and when the viscosity is small, the amount of grinding media can be slightly more.

For horizontal sand mills, the amount of grinding media can start from 75% of the simplified volume. The emulsifier pump then increases or decreases the amount of grinding media according to the discharge temperature of the material or the temperature of the cooling water. Generally speaking, when the temperature exceeds the allowable When the range is set, the amount of grinding media should be reduced. When the temperature is lower than the allowable range, before increasing the shaft speed, the static mixer can be given priority to increase the amount of grinding media. Generally, the discharge temperature of the milled slurry is acceptable in the range of 50-70°C.
