摘要:
A method for making a slurry containing particulate matter and fibers for a preformed insulation product comprises mixing dry particulate matter with a binder which is a liquid containing dispersed fibers. An apparatus suitable for practicing the method comprises a means for disposing the particulate matter in the form of a falling curtain and a means for spraying the binder on the particulate matter.
