A comparison of the sie reduction by impact and ball mill grinding is shown in figure 2. The ball mill experiments show the sie reduction versus energy input for 7 series of experiments in which the weight of dolomite was 660 1320 1980 2640 3300 3960 and 5420 respectively.
Our products sell well all over the world, and have advanced technology in the field of crushing sand grinding powder.
The present state of the art generally accepts a particle sie range for lime or limestone of 95 less than 44 microns or 325 mesh. For example for SO 2 capture with ground limestone in wet FGD much of the coarser particles never react with gasses because of a short contact period and these particles are basically wasted.

Based on particle sie distribution it was concluded that the suitable condition for the dry grinding of limestone took place with balls of 10 mm diameter and revolution speed at 200 rpm. After 30 min of grinding under this condition the mean particle sie was reduced from 134 to 9 m and the dispersion factor reached a value near to 25.
