Mar 04, 2014· In the United States, crude perlite ore production (424 000 metric tons in 2012) came from eight mines operated by six companies in five Western States (see Bolen, 2012, 2013). New Mexico is the major producing state in the United States. Processed crude perlite was expanded at 50 plants in 27 states (Bolen, 2013).

Perlite is a generic term for naturally occurring siliceous rock. It is a form of natural volcanic glass with 70-76% amorphous silica). It expands 4-20 times its original volume, when rapidly heated to its softening temperature range (above 850 o C), due to the presence of "combined water" (2-6%). Perlite expansion is taking place as the H 2 O molecules vaporize and create numerous tiny ...
Crude perlite expanded for use as a concrete aggregate ranges from 1 mm (plus 16 mesh) to 0.2 mm (plus 100 mesh). Ninety percent of the crude perlite ore expanded for horticultural uses is greater than 841 µm (20 mesh). Crude perlite is mined using open-pit methods and then is moved to the plant site where it is stockpiled.
The expansive process is a lot like making pop corn. The resultant expanded perlite can be 20-30x its original bulk density. The process of expansion targets the combined water content within the raw perlite - the water trapped in the perlite ore - which vaporizes under heat and creates a glass bubble.

PRODUCTION PROCESS. Perlite ore: production occurs in two stages; extraction of the crude ore at the mine, then drying & milling. Expanded Unmilled Products: the perlite ore is injected into a naked flame in the base of the expansion tower. The perlite becomes soft enough to be expanded by its internal water which is vaporized.
process for manufacturing expanded perlite. perlite insulation manufacturing process - moulindemembre. The reason perlite insulation is technically referred to as "expanded perlite" is because when it is heated during the manufacturing process (to approximately 1600°F/900°C) the moisture expands, causing it to pop like popcorn at 1600°F.
