METHOD OF CONTINUOUS MIXING OF RUBBER COMPOUNDS AND DEVICE FOR ITS REALIZATION Russian patent published in 1998 - IPC

FIELD: method of continuous mixing of rubber compounds and device for its realization. SUBSTANCE: one or several base elastomers, as well as other components of rubber compound to be prepared, are dosed and introduced into mixing chamber. The majority of components is introduced into mixing chamber by force by volumetric pumping along the zones of pushing through and mixing. The degree of mixing chamber filling at least in some mixing zones makes up a value of less than unity. All the components of rubber compound are advanced in the direction of material flow and mixed by means of at least one revolving rotor installed in mixing chamber. The device has also members for dosing and forced introduction of base elastomers and other components of the compound to be prepared, capable of pushing them through under pressure into mixing chamber. The members for dosing and introduction of components are located between the upper and lower ends of mixing chamber at least in two places separated from one another in the longitudinal direction. EFFECT: facilitated procedure. 30 cl, 6 dwg
