ABSTRACT:
In method for the dewatering of naturally moist, coarse lump peat or of a similar material, the material is continuously fractured into particles to approximately 2-3 cm diameter and is dispersed onto a lower screen belt. With the leading in of a provided upper screen belt the material is conveyed between the two screen belts through a preliminary dewatering zone, where at a pressure which is only given through the tension of the screen belts in a loop on at least one pair of rolls, a homogeneous filter cake is produced. The latter is pressed in a subsequent dewatering zone of a number of pairs of nip rolls at a pressure increasing along the zone between screen belts, whereby in each case between the screen belt and the nip roll a pressure belt, equal in width to the screen belt, is carried long, consisting of an elastic, watertight material, but which is designed to receive and carry away the filtrate and to stabilize the material which is to be pressed. After the dewatering zone, the material arrives into a high pressure zone, where it is treated between screen belts between at least one pair of press rolls at a greater pressure than on the last pair of rolls of the dewatering zone.
