lower grinding limits of roller diameter will be made to good use by generating new weighting arm. However, the amount of top roller pressure for the new roller diameter as well as for roller diameter after grinding cycles is still the same and no effort is taken to vary and optimize the top arm pressure. II. MATERIALS AND METHODS A. Material

After the final feed input, the material grinds between the roller and the mill due to the relative motion of the mill and roller [17]. In between these all processes feeding, classifying & grinding, material gets dry and unable to form stable bed. The dried material unstable grinding bed causes vibration in VRM and can stop the mill.
