Tablet was prepared by direct compression method. In the first step, drug was milled in Ball Mill (Hicon Lab. India) for specific time. Then it is mixed with other excipients using Double Cone Blender (Hicon Lab. India) for certain time. The blended powder was directly compressed using Rotary Tablet Punching Machine (Krishna Engineering
Milling in an attrition mill (Fig. 24) is effected by the stirring action of an agitator that has a vertical rotating shaft with horizontal arms. This motion causes a differential movement between the balls and the material being milled, thus providing a substantially higher degree of surface contact than is achieved in tumbler or vibratory mills..
