Mixing is generally done with a twin-screw extruder, and the single-screw extruder, which is used in product production, is generally overlooked as a device for mixing. This reference handbook, written by a former Principal Consultant at Smithers Rapra, and the inventor of the cavity transfer mixer, redresses the balance; This handbook is a must-have practical guide to the subject of single-screw extrusion. Avoiding mathematical theory, except when absolutely necessary, this authoritative handbook empowers the reader to achieving good results with their plastic mixing. Mixing in Single Screw Extrusion will be a valuable resource to all involved in the art of plastic extrusion. --Book Jacket UR - https://search.ebscohost.com/login.aspx?direct=true&scope=site&db=nlebk&AN=288183 ER -
