ore. Principle is: By preheating，fire，rapid heating(***0℃
above)，then the moisture vaporizing,the crushed special size ore
is expanded in softened ore to be porous structure，become
original ****0 times.The expanded perlite can be sorted to 3 shapes
by the technical of expansion.It is open hole(OPEN
CELL),obturator(CLOSED Cell), hollow (BALLOON).
