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.

摘要:
An apparatus and dry method for de-shotting shot-containing mineral wool fibers wherein the fibers are treated in a granulator to compact them into entangled nodules, and the nodules are passed through an air classifier to open up and de-shot them. In a preferred embodiment, a felted layer of mineral wool is subjected to a first granulation step to divide the layer into a multiplicity of lightly compacted nodules which are then partially de-shotted, and the partially de-shotted nodules are subjected to a second granulation step to more tightly compact the nodules before they are introduced into the air classifier.
