The body includes an inlet passageway, a cylindrical passageway connected to the inlet passageway, and a conical passageway connected to the cylindrical passageway. The cylindrical passageway has an upper end through which first particles in a fluid are exhausted, and a lower end. The conical passageway has an upper end connected to the lower end of the cylindrical passageway, and an opened lower end through which second particles having a specific gravity greater than that of the first particle are exhausted. The vortex finder is connected to the upper end of the cylindrical passageway. A first exhaust passageway is vertically formed in the vortex finder so that the first particles spirally ascend through the first exhaust passageway from the cylindrical passageway.
