Advances in cellulose nanomaterials | SpringerLink
Grinding. In the grinding process, cellulose fibers are forced through a gap between two specially modified grooved discs, one of which is static and the other revolving at about 1500 rpm. During the process, the cell wall structure is broken down by the high shear forces, resulting in the production of individual nanosized fibers.
