    摘要: A process for continuously manufacturing a lubricating grease using a screw process unit comprising:(a) introducing feed materials and lubricating oil into selected locations of a screw process unit which contains a series of adjacent, longitudinally connected barrel sections for performing different operative steps and houses a rotating screw device traversing the interior of the barrel sections and having separate elements along its length to perform desired operations;(b) mixing and conveying said feed materials along said process unit through the adjacent barrel sections by continuous operation of said rotating screw;(c) controlling the temperature of said material while it is being conveyed through said process unit by use of various heat exchange means which are located in or adjacent each barrel to aid in carrying out the operative steps of dispersion, reaction, dehydration and/or homogenization;(d) venting water resulting from the dehydration of the feed mixture at selected barrel discharge points in said process unit;(e) introduction of additional lubricating oil and/or additives at downstream barrel locations following the dehydration step;(f) homogenization of said complete grease formulation by continued rotation of said screw device; and(g) removal of the finished lubricating grease from the end barrel section of said screw process unit.
