The process is mixing is carried out between two contrary rotors. The wicks of the both the rotors are arranged in parallel manner and posses different speeds. Due to the difference in tangential speed and nip constriction, rubber compound experiences displacement and pressure energy during the process of mixing. Pressure energy increases the displacement energy, and displacement energy will break the rubber molecule bonding. The breakage of rubber molecules allow carbon and other chemicals to be uniformly mixed with rubber.
