METHOD OF OBTAINING FREE-FLOWING POWDERY SULFITE LIQUOR

摘要

The flowability of sulphite waste liquor powder or prods. obtained therefrom (which are added to feedstuffs in an amt. of 2-5% to diminish abrasion of fodder pressings and granulates and to increase durability) is improved by adding finely divided black carbon such as ground wood charcoal, ground coke, soot or the like. Partic. an additive is used obtained by ignition of dry clay to which particles of org. materials (e.g. humic acid) adhere. Th black carbon additive improves the flowability of the sulphite waste liquor powder material without adversely affecting its binding agent props.
