NIR testing of feed particle size

The promise of NIR Given that many feed mills today already have NIR analysis equipment in place it would make perfect sense to use it as a rapid method – no sieving, no manual recording, just put the sample in the sample cup and push the start button To investigate the possibility, Fahrenholz embarked on a calibration project aimed at getting enough data on particle size variation to ,
