AB  - The fabricationof nano-sized materials with conventional ball mill is a very difficultprocess. But it is not impossible. When the capacity of the mill is reduced,the nano-sized product can be reached. In this study, nano-sized calcite wasproduced by conventional ball mill. Firstly, the mill capacity (feed amount)was reduced, then, the effect of the grinding media type was investigated.Spherical ball and cylindrical shaped “Cylpebs” are used as grinding media. Comparative tests have been performed using Cylpebs and spherical ballsin a 20 tph capacity industrial ball mill under the same conditions. Theresults showed that Cylpebs was more efficient than conventional spherical balls. In addition, the capacity of the conventional ball mill for the fabricationof nano-sized products should be significantly reduced. When the mill capacityis reduced by 75% (5 tph) and grinded with Cylpebs, the fineness (d90)of the product reaches 1300 nanometers
