Ball milling experiments were done in a high energy planetary ball mill at a rotating speed of 300 rpm. To avoid the occurrence of any undesirable polluted phases, the ballmilling experiments were halted periodically (every ks) and then restarted when the temperature of the vial reached about 300 K.

A pharmaceutical ball mill is a type of grinder that is used to grind and combine materials in the production of different dosage forms. Impact reduces the size of the balls as they fall from near the top of the shell. Ball mills are commonly used in single stage fine grinding, regrinding, and as the second stage in twostage grinding circuits.

BALL MILL Principle Th ball mill work on the principle of impact between the rapidly moving ball the powder materiel, both enclose in a hollow cylinder. At low speed the ball role over each other attrition will be predominant mode of action. Thus, in boll mill impact or attrition or both are responsible for size reduction.

The dissolution rate increased when ball milling time was increased from 30 min to 60 min, as shown in Fig. 6. However, at longer periods (>45 min), the mixtures became sticky and had poor flowability and was difficult to extract from the milling jar. Dissolution rate in 60 min ball milling time was similar to that in 45 min.
