First Claim
Patent Images
1. A method for making cellulosic particles comprising:
- (a) agglomerating a moist blend of fibers, aggregates of fibers, and/or fiber-sized pieces of a fibrous cellulosic material in a substantially horizontal rotating drum to form individual agglomerated particles;
(b) compacting the surface of the agglomerated particles to form a densified skin substantially free of protruding fibrils; and
(c) drying the agglomerated particles.

5. A method for making cellulosic particles comprising:
-
(a) agglomerating a moist blend of fibers, aggregates of fibers, and/or fiber-sized pieces of a fibrous cellulosic material in a substantially horizontal rotating drum to form individual agglomerated particles, said moist blend having from about 75 to about 85 weight percent moisture; (b) compacting the surface of the agglomerated particles; (c)partially drying the surface-compacted particles to from about 30 to about 50 weight percent moisture; (d) forming the partially-dried particles into platelets; and (e) drying the particles to a moisture content of about 10 weight percent or less. - View Dependent Claims (6, 7, 8, 9, 10)
