A biomass pellet production process includes initial size reduction of biomass having at least 30% by weight moisture content to about 15-mm particle size, followed by a second-stage grinding process to reduce the particle size to less than 5 mm, typically to 2 mm. The ground biomass is preheated and pelletized, after which the biomass pellets ...
