Measuring Success: How We Test Granulations
Source : Yenchen Technical Process Consultant, Dr. Fred Rowley
Before we construct a granule, let us first learn how we test the finished granule and determine we have met our goal. We may have more than one goal: how much moisture, how many fines, how many large particles, how many small particles.
Loss on Drying - LOD: Also Called Residual Moisture (water)
- Tested on a moisture analysis instruments.
- Result usually given in % moisture.
Bulk Density
- Usually recorded as mg./ml. or gm./cc.
The Concept of Particle Size Distribution
- Usually recorded as a percentage on a specific screen.
- Very sensitive and predictive.
- Excellent test.
