Image analysis and calliper measurements.

Pellet size results in pixels and millimetres for start and stop of the batch production. Production diameter (mm) is the target size of the produced pellets. Calliper diameter (mm) is the manually measured size of 51 pellets. Morphological opening radius (pixels) is the radius with the highest density in the pattern spectrum. Opening diameter (mm) is the opening radius converted from pixels to diameter in millimetres. Calliper measurements were only done on batch C and D. Pellets in dry condition.
