Conditions

Temperature
192 fahrenheit

Procedure

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 stearic acid melted, flowed onto the granules of magnesium oxychloride coated mineral supplement granules and reacted with the magnesium oxide to form a dry, solid magnesium stearate coating on the outside of the granules. The magnesium stearate coating amounted to 1.22% of the total weight of the granules.

Workup

  1. additionStandard Screen) were added
