Grinding and granulation in a vibratory ball mill ...

INTRODUCTION Vibratory ball mills are used extensively in the pharmaceutical industry as a simple, economical and rapid means of particle size reduction. However, prolonged comminution in this type of high energy mill results in a practical grind limit, or Huttig grinding equilibrium [1], due to agglomeration of ground particles.
