View of the mixing mill used in the Rubber Compounding and Processing Laboratory at the Naval Air Experimental Station. The mill is an Adamson 6" by 16" two-roll machine powered by a 7 1/2 H.P. motor with chain drive. At the laboratory, the mill was used to mix rubber stocks or warm mixed stocks for subsequent processing. This photograph was included in a 1949 Naval Air Experimental Station report on compounding rubber.</div>
