Abstract

A method for fractioning of peat wherein raw peat is extracted from a moss in a suitable way and is passed to a homogenizing vessel wherein the peat is mixed with process water and is agitated so that a homogenous suspension having a mean concentration of about 1,5-5,0% is obtained. After the homogenization the peat suspension is passed to a coarse screen, wherein coarser components are removed, and from there the suspension, having a concentration of 1,5-4,0% is passed to a hole or slot screen wherein the concentration is increased to about 3,0-6,0 per cent by weight. The accept from the hole or slot screen is then passed to a dehydration means wherein it is dewatered to a dry substance content of the order of 15-20%, or to the order of about 30%, if the dehydration means is a screw or screen band press or the like. The fibre poor accept from the hole or slot screen is preferably passed to a fine screen from which the accept has a dry substance concentration of the order of about 0,7 per cent by weight, as a maximum.
