ABSTRACT:
A mixer mixes at least two fluid components of the type which when mixed together undergo chemical reaction to form a solid or semi-solid reaction product. The components are separately introduced into the mixer, whereat they are mixed, and the reaction mixture is discharged from the mixer prior to the completion of the chemical reaction and while still in a fluid state. When desired, for example when it is necessary to shut down the operation of the mixer, the chemical reaction in the mixer is arrested by selectively cooling the reaction mixture down to a temperature at which the chemical reaction will not occur or will at least be retarded. This prevents the formation of the reaction product within the final mixer. Thereafter, for example when the operation of the mixer is again commenced, the reaction mixture is reheated to an increased temperature at which the chemical reaction will continue.
