Product from Example 1, amounting to 50 pounds, was placed in a rotary drum dryer and was heated to 192° F. Then 0.41 pounds of commercial grade stearic acid and 0.205 pounds of magnesium oxide powder (93% passing through a 300 mesh U.S. Standard Screen) were added.

The magnesium stearate coating amounted to 1.22% of the total weight of the granules.
