| 摘要 |
<p>The invention is a finely ground biomass material made from biomass material, where at least 98% of the biomass particles have a particle size of 20 microns or less. The invention also provides a method for producing finely ground biomass material from biomass material. The biomass material is first ground using a hammermill equipped with a screen having a screen with a 0.5 millimeter or smaller hole pattern until all the ground biomass particles have passed through the screen. The hammermilled biomass particles are then ground with a dry grinding attritor until less than 2% of the particles have a particle size greater than 20 microns. The method may also include forming a slurry by adding water to the ground material. The slurry may then be processed using a high shear and cavitation device, dried, and processed with an attrition mill to disagglomerate agglomerated material in the dried material.</p> |
