Perlite is a form of volcanic glass unique for its ability to expand up to 20 times its original size when heated to approximately 900°C. This expansion process creates a lightweight, porous material with remarkable water and air retention capacity, making it an invaluable resource in various industries.

A thermally efficient process for the expansion of perlite ore is described. The inlet port and burner of a perlite expansion chamber (preferably a vertical expander) are enclosed such that no ambient air can enter the chamber. Air and fuel are metered to the burner with the amount of air being controlled such that the fuel/air premix contains at least enough …

The perlite expansion process takes place in specialized furnaces, where the raw ore is heated to temperatures around 1,600°F (870°C). The sudden heat causes the moisture inside the ore to vaporize and expand, creating countless tiny bubbles that give expanded perlite its characteristic lightweight and porous structure.
