The lowgrade limestone (LGL) used in this work was obtained from the quarry in Inner Mongolia, China. To eliminate the effect of particle size and water adsorption, The LGL was initially pulverized and ground to 400 mesh (average particle size below 20 μm) by a hammer breaker and a ball mill, and then was dried at 105 °C for 8 h in a drying apparatus (Memmert UF 260).

The ball milling process is carried out for approximately 100150 h to obtain uniformsized fine powder. In highenergy ball milling, vacuum or a specific gaseous atmosphere is maintained inside the chamber. Highenergy mills are classified into attrition ball mills, planetary ball mills, vibrating ball mills, and lowenergy tumbling mills.
