Agglomerated animal litter and manufacturing process for the same
An animal litter is provided that includes a sorbent granule composed of granule particulate that is able to pass −20 screen sieve and a binder such that greater than 90% of said granules have a size of between −5 and +60 screen sieve. The granule has an oil coating thereon. An animal litter is produced by milling sorbent material to a particulate size such that greater than 90% by weight of said particulate is −20 screen sieve size or finer. The sorbent material is then agglomerated to the milled particulate to a granule size of between −5 and +60 screen sieve with a binder. The granule is then coated with an oil. Extrusion represents a preferred mode of agglomeration.
1. An animal litter comprising:
a plurality of sorbent granules each of said plurality of sorbent granules comprising granule particulate that is 90% by weight or more able to pass −20 screen sieve and a binder such that greater than 90% of said granules have a size of between −5 and +60 screen sieve; and
an oil coating on each of said plurality of sorbent granules.
2. The animal litter of claim 1 wherein said granule particulate is selected from the group consisting of: corncob; bentonite; diatomaceous earth; attapulgite; montmorillonite; cellulosic plant stalks, husks and hulls.
3. The animal litter of claim 1 wherein said granule particulate is corncob.
4. The animal litter of claim 1 wherein said plurality of sorbent granules are cylindrical in shape.
5. An animal litter comprising:
a plurality of sorbent granules each of said plurality of sorbent granules comprising granule particulate that is 90% by weight or more able to pass −20 screen sieve and a binder wherein greater than 90% of said granules have a size of between −5 and +60 screen sieve; an oil coating on each of said plurality of sorbent granules; and
clumping agent particles decorating the surface of each of said plurality of sorbent granules.
6. The animal litter of claim 5 wherein said clumping agent is selected from the group consisting of: gum of guar, arabic, karaya, tragacanth or locust bean; celluloses of corn syrup, carboxymethylcellulose, ethylcellulose, hydroxyethylcellulose, hydroxy-methylethylcellulose, hydroxyethylpropylcellulose, methylhydroxyethyl-cellulose, or methylcellulose; starches of amylose, seagel, starch acetates, starch hydroxyethyl ethers, ionic starches, long-chain alkyl starches, dextrins, amine starches, phosphates starches, or dialdehyde starches; and plant starches of corn starch or potato starch.
7. The animal litter of claim 5 wherein said clumping agent is a gum.
8. The animal litter of claim 7 wherein said gum is guar gum.
9. The animal litter of claim 5 wherein said clumping agent has a size distribution such that greater than 90% of the clumping agent particles are −20 screen sieve or finer.
10. The animal litter of claim 5 wherein said granule particulate is selected from the group consisting of: corncob; bentonite; diatomaceous earth; attapulgite; montmorillonite; cellulosic plant stalks, husks and hulls.
11. The animal litter of claim 5 wherein said granule particulate is corncob.
12. The animal litter of claim 5 wherein said plurality of sorbent granules are cylindrical in shape.
