Abstract Taguchi's method was applied to investigate the effect of main high energy ball milling (HEBM) parameters: milling time (MT), ball to powder weight ratio (BPWR), and milling speed (MS) on the CaCO 3 crystallite size. The settings of HEBM parameters were determined by using the L9 (3 3) orthogonal experiments array (OA).

Ball mill The calcium carbonate ball mill works by rotating a cylinder with grinding media, causing the media to fall back into the cylinder and on to the material to be ground. The ball mill can be operated either wet or dry. The particle size of the finished product can be adjusted by controlling the grinding time, rotating speed, size and composition of grinding media, additives, etc.

crystals as a result of the increase in ball milling time. The highest yield (94%) and shortest reaction time (10 min) were achieved for nanoCaCO 3 with 4 h of the ball milling time. This proves the essential effect of ball mill treatment on the catalytic activity of eggshell powder as a mild and efficient catalyst in the reaction (Table 1).

Calcium carbonate scale formation is greatly affected by pH. Any high solids system with a pH over has a potential for calcium carbonate scaling. In many applications, pH is maintained above to prevent corrosion problems. However, if pH control is not closely maintained, system pH can approach the calcium carbonate scaling range.
