Abstract
Official abstract text for this publication.
A clumpable animal litter comprises composite particles of filler materials, such as limestone and sand, and sodium bentonite. The filler materials have a lower bulk density as compared to a granular mixture of the same percentage of filler and sodium bentonite clay and contain up to eighty-five percent less clay.
First claim
Opening claim text (preview).
The invention claimed is: 1. An animal litter comprising: composite particles of a filler material and sodium bentonite, the filler material and sodium bentonite being agglomerated together into the composite particles, wherein the filler material is present in an amount from about 60% to about 80% by weight of the composite particles and the sodium bentonite is present in an amount from about 20% to about 40% by weight of the composite particles; wherein the animal litter has a clump strength of at least 90% as measured by the Clump Strength Test Method. 2. The animal litter recited in claim 1 , wherein the filler material is present in an amount of about 70% by weight of the composite particles, and the sodium bentonite is present in an amount of about 30% by weight of the composite particles. 3. The animal litter recited in claim 1 , wherein the animal litter has a clump strength of at least 93%. 4. The animal litter recited in claim 1 , wherein the composite particles have a bulk density greater than 60 lb/ft 3 . 5. The animal litter recited in claim 1 , wherein the composite particles have a mean particle size from 0.4 mm to 2 mm. 6. The animal litter recited in claim 1 , wherein at least one of: (i) the filler material has a mean particle size of 0.5 mm or less; or (ii) the sodium bentonite has a mean particle size of 0.25 mm or less. 7. The animal litter recited in claim 1 , wherein the composite particles further comprise powered activated carbon. 8. The animal litter recited in claim 1 , wherein the filler material is limestone. 9. The animal litter recited in claim 1 , wherein the filler material comprises at least one of limestone, dolomite, calcite, calcium carbonates, sand, shale, gravel, or slate. 10. An animal litter comprising: composite particles of a filler material and sodium bentonite, the filler material and sodium bentonite being agglomerated together into the composite particles, wherein the filler material is present in an amount from about 50% to about 80% by weight of the composite particles and the sodium bentonite is present in an amount from about 20% to about 50% by weight of the composite particles; wherein the animal litter has a clump strength of at least 90% as measured by the Clump Strength Test Method. 11. The animal litter recited in claim 10 , wherein the composite particles further comprise powdered activated carbon. 12. The animal litter recited in claim 10 , wherein the filler material is limestone. 13. The animal litter recited in claim 10 , wherein the filler material comprises at least one of limestone, dolomite, calcite, calcium carbonates, sand, shale, gravel, or slate. 14. The animal litter recited in claim 10 , wherein the composite particles have a bulk density greater than 60 lb/ft 3 . 15. The animal litter recited in claim 10 , wherein the composite particles have a mean particle size from 0.4 mm to 2 mm. 16. The animal litter recited in claim 10 , wherein at least one of: (i) the filler material has a mean particle size of 0.5 mm or less; or (ii) the sodium bentonite has a mean particle size of 0.25 mm or less.
