摘要： The operation of dewatering and drying devices which consist of a dewatering centrifuge and a concentrically arranged spray drier may be disturbed by leaks between the drier housing and the centrifuge or by deposits and encrustation of solid particles inside the drier. In order to avoid these disturbances, the rotating outer surface of the centrifuge (1) is sealed with respect to the fixed front walls (13, 14) of the drier housing (11) by a sealing system in two or more stages which consists of rotary seals (160) and elastic or sliding sealing elements (180, 260, 300, 340). The rotating outer surface of the centrifuge (1) is provided, with turbulence-generating means (32, 33, 40, 42, 46), preferably torus-shaped turbulence-generating rollers, arranged inside the drier housing (11).
