Henschel mixer is most frequently used for dryblending. " In such a mixer, the technological process includes addition steps and temperatures which must be reached in order to proceed to the next step. Order of addition is considered important. The following order of addition is usually suggested resin, stabilizer, plasticizer, filler, lubricant. Stabilizer is added to the resin before it is subjected to heat, and lubricant is added at the end because it may interfere with plasticizer absorption. - Temperatures which determine the end of the mixing step depend on the amount of plasticizer in a mixture (the higher the amount of plasticizer, the higher the temperature). Final temperature of dryblend is between 90 and 110°C. Premixed dry blend is then cooled to below 50°C. ... 

The formulation is given in Table 10.1. The raw elastomer was an NBR copolymer powdered rubber with a Mooney index of 80 (ASTM D1646 [7]). The powder was preblended with a high-intensity Henschel mixer. 

A mixture of soy protein isolate (raw polymer) (100 parts) and nanoelay (Cloisite 3 OB) (10 parts) was mixed in a high-speed mixer (Henschel Mixers American, Inc., Houston, TX) to uniformly distribute the ingredients. To prevent elumping of the mixtme, a solution of water (80...
