Detailed Perlite Production Plant Description:


Perlite is not a trad name but a generic term for naturally occurring siliceous volcanic rock. The distinguishing feathure which sete perlite apart from other volcanic glasses is that when heated to a suitable point in its softening rang, It expands four to twenty times its original volume. This expansion is due to the presence of two to six percent combined water in the crude perlite rock. When quickly heated to above 1600 f (870 c) the crude rock pops in a manner similar to popcorn as the combined water vaporizes and creates countless tiny bubbles in the heat softended glassy particles. It is these tiny glass_ sealed bubbles which account for the amazing physical properties of expanded Perlite.
