Abstract

In order to create a solid-bow centrifuge for mechanical drainage and thermal drying of sludges, in which the possibility of clumping or of bake-on of the finely dispersed thick matter spun off from the thick matter outlet openings is minimized or prevented, according to the invention it is proposed to provide in the flight path of the spun off thick matter, a baffle cone surrounding the thick matter outlet openings at a distance and which rotates at a high circumferential velocity, that is, preferably it rotates together with the basket shell, and whose inner, ring-shaped, rotating conical surface accelerates the arriving thick matter and prevents solids bake-on.
