VARIABLE INTERMESHING CLEARANCE MIXER

A comparative study was made of the effidency of two intermeshing rotor mixers, one with fixed clearance and the other a VIC 165 variable intermeshing clearance mixer (Techint-Pomini), in the mixing of NR, EPDM and polyepichlorohydrin compounds. The results showed that the variable clearance mixer gave reduced cycle times with equal quality of the compounds produced, and that higher fill factors were possible with this mixer. The cost advantages of the VIC 165 were also analysed. [Pg.56]

The authors compare the performance of a variable intermeshing clearance mixer, which offers the possibility of varying the intermeshing clearance between the rotors in addition to the usual adjustable process parameters, with that of conventional mixers with intermeshing rotors. 3 refs.

The factory system based on internal mixers, screw extruders, calenders, and vulcanization presses has remained basically unchanged in the past half-century. Internal mixers have had major improvements, e.g., intermeshing rotors proposed by Francis Shaw and Company [C16] and Werner and Pfleiderer [L3], and variable intermeshing clearance rotors [PI] proposed by Pomini-Farrel SpA. Sophisticated computer control systems have been introduced. The early single hot-feed extruders have been replaced by cold-feed extruders with increasingly sophisticated design including pin barrel extruders [G7, H12, H13, M18, W16] as well as complex control systems.

A variable intermeshing clearance style mixer is an internal mixer with intermeshing rotors that provides technologists and compounders with the ability to control and adjust the variation of the clearance between the rotors. By adjusting the gap between the rotors, it is possible to optimise the amount of energy to be transferred to the compound in accordance to its actual viscosity. The results on mixed compounds presented in this article are based on tests run with industrial sized machines directly at the customer s production facility. 8 refs. [Pg.107]
