Process for the concentration of solutions with simultaneous setting

Liquid solutions are evaporated to their setting points and the set material so formed is crushed in a screw machine. The phase conversion from the still viscous state to the flowable crushed solid state is carried out in a single closed housing zone of the screw machine and comprises simultaneous e...

More Information
Summary:Liquid solutions are evaporated to their setting points and the set material so formed is crushed in a screw machine. The phase conversion from the still viscous state to the flowable crushed solid state is carried out in a single closed housing zone of the screw machine and comprises simultaneous evaporation, setting, crushing and further concentration.
