Sand mills can be used to grind many products, such as inks, pigments, etc., and have many applications in many industries. The amount of grinding media used in the sand mill is related to the viscosity and temperature of the grinding material. If the viscosity of the material is high, then the amount of grinding media should be small, on the contrary, if the viscosity is low, the grinding media can be used a little more.
1. The amount of grinding media is related to the viscosity of the material. These results need to be obtained through experiments. The amount of grinding media for sand mills with different structures has different standards. Usually, the volume of grinding media is set at The volume of the cylinder is about 50%. For example, in a vertical sand mill, the amount of grinding media can be so large that the surface of the media piled in the cylinder is just lower than the upper impeller, so that the grinding media can have room to rise. Of course, speed must also be considered
2. The material used for the grinding medium of the horizontal sand mill can usually start from 50% of the volume of the grinding cylinder, and then increase or decrease according to the feeding pressure, the discharging temperature and the working current of the motor. Generally, the filling amount is reduced when it exceeds the range, and the filling amount can be gradually increased within the allowable range.
No matter what kind of sand mill, the materials to be ground must be fully pre-dispersed, so that the normal working efficiency of the sand mill can be exerted, and the grinding effect will be better.
