Abstract
A method of making agglomerated cellulosic particles, particularly useful as a cat litter, comprises 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 agglomerated particles; compacting surfaces of the particles; and drying the particles.
Claims10
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.

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.
