Originally screw extruders were simply used as pumps. However, in the second decade of the 20th century, there were efforts to use single-screw extruders as continuous mixing machines. 39 In later patents of the 1920s and 1930s, notably by Gordon 40 and Royle, 41 this trend became clear. Here, serrated barrels are introduced to aid the mixing process notably for rubber and its …

nents is to use a screw to clamp the joint members with a nut or directly to a threaded hole in one of the components. The advantages of this method are the simplicity of design and assembly, easy disassembly, productivity and in the end – cost. 2. THE SCREW JOINT A screw is exposed to tensile load, to torsion and sometimes also to a shear load.

The design of the screw is based on the theory of the inclined plane. The screw conveyor began to evolve in the late 1800s and was used as a means of increasing food and grain production to meet the needs of the rapidly growing American population. The first feed mills used screw conveyors throughout the process.
