Calcium Stearate → Ethanox 330 Calcium Stearate

Participants

Reaction Steps

2.98 lb of calcium stearate powder (Hydense 5862, obtained from Mallickrodt), 4.26 lb of Ethanox 330 powder, and 12.76 lb of GMS-40 powder were combined and tumble blended for 3 minutes to obtain a homogenous powder blend. This powder blend was processed with the pellet mill under essentially the same conditions/procedures of Example 1, except the powder feed rate to the pellet mill was bout 47 lb/hr and the die temperature ranged from about 42° C. to about 47° C. The output from the pellet mill consisted of 91.5.% by weight cylindrical pellets of nominally 3 mm diameter, the balance being −12 mesh fines. The pellets thus obtained exhibited good abrasion resistance and therefore would handle well in powder metering and conveying equipment.
