    摘要： This invention relates to a method for producing a pigment-organic vehicle product, commonly referred to as "flush" by those versed in the art, which comprises forcing a pigment-containing aqueous pulp-organic vehicle mixture through a chamber comprising a set of at least two adjoining partial cylindrical surfaces, said chamber having defined at one end thereof at least one axial opening and at least one second opening spaced from the axial opening. The mixture is forced through the chamber and axial opening by a set of at least two rotating helical surfaces whereby the product is extruded through the axial openings. The water exits from the chamber through the second opening or openings.
