For estimating the grinding efficiency, it was strenuous and impractical to conduct multiple grinding tests on mono-size feeds in order to realize the exact reduction ratio of 2. Therefore, since the values of S i E and B had already been obtained, the actual physical tests could be substituted with simulations using an energy-based population balance model [22] .

5 Factors Affecting the Grinding Efficiency of Sand Mills

If you want to improve efficiency, you must increase the speed, but if the speed is too high, it will cause excessive energy consumption. In this case, the grinding equipment is prone to shaking. On the other hand, if you want to obtain a higher speed, the requirements for the shaft are relatively high, and the cost is correspondingly increased.
