PROBLEM TO BE SOLVED: To provide an apparatus in which secure solid-liquid separation is carried out even if a solid component is fine and has a hardly entwined shape such as honing sludge, complicated maintenance such as filter replacement is not required, and most suitable pressurizing is carried out without causing a breach of the filter. SOLUTION: The apparatus includes a mold 1 forming an internal diameter face into a cylindrical face shape, a gate 2 switchably closing the one end opening of this mold 1, and a pressure rod 3 slidably fitted in the mold 1 and pressing a slurry material S in the mold 1 to the gate 2 side to compress it. A pressure device 14 which moves this pressure rod 3 forward and backward, and its pressure control device 33 are provided. The tip end face of the pressure rod 3 and the internal face of the gate 2 have the arrangement of fibrous and paper filters 4 and 5 to compress them. The pressure control device 33 controls pressure such that the pressure applied to the slurry material in the mold becomes less than a predetermined pressure. COPYRIGHT: (C)2007,JPO&INPIT
