Integration of size reduction and separation focuses on particle characteristics as measured in this project. Create (size reduction mill and operating factors) and sort (sieve and/or terminal velocity) particle sizes to achieve desired chemistry:

1. Chemistry of biomass can be related to anatomical component

Fig 1. Chemistry of switchgrass anatomical components

2. Particle sizes can be controlled through size reduction and/or sieving
