               The causes and remedies of cracking
               a.  Causes related to formulation (granulation):

                               Causes                                  Remedies


                       Large size of granules              Reduce granule size. Add fines.


                         Too dry granules.                Moisten the granules properly and

                                                             add proper amount of binder.

                       Granulation too cold.               Compress at room temperature.


               b.  Causes related to machine:

               Reason: Incorrect machine settings, especially miss-set ejection take-off.
