METHOD FOR PRODUCING NON-CAKING LIGNOSULFONATE BASED BINDERS FOR PELLETING OF ANIMAL FEEDSTUFFS

摘要

A non-caking lignosulfonate based binder suitable for pelleting animal feedstuffs is obtained by compounding calcium, magnesium or sodium based sulfite spent liquor in the dry state with a calcium oxide and/or a calcium hydroxide containing compound. The amount of calcium compound used is such that the pH of a 5% aqueous solution of the obtained blend is greater than 5 measured at room temperature. The obtained binder has excellent non-caking and binding properties for a large range of animal feedstuffs.
