FIELD: transport; technological processes.;SUBSTANCE: invention relates to process equipment for separation of liquid from transported material. Press comprises screw shaft (11) with spiral-like located on it supply spiral (13) and enclosing envelope spiral (14). Between spiral shaft (11), feed spiral (13) and shell (14) there is transport gap (15). Composite material (21) containing particles (23) of solid substance is fixed with at least one section (20) of surface of screw shaft (11) in transport gap (15) with closure of material. Said particles are immersed in matrix component (24) to form surface roughness (22).;EFFECT: as a result, it is possible to replace rough coating on auger shaft.;11 cl, 3 dwg
