What is perlite? Perlite is a lightweight granular material that's white in colour. It looks and feels like little bits of polystyrene but is actually made from expanded volcanic glass, heated to 1000°C until it 'pops' (like popcorn) to many times its original size. It's lightweight, sterile, and easy to handle, and is long-lasting.

Perlite is an amorphous volcanic glass that has a relatively high water content, typically formed by the hydration of obsidian. It occurs naturally and has the unusual property of greatly expanding when heated sufficiently. It is an industrial mineral and a commercial product useful for its low density after processing.

The Benefits of Perlite as Insulation. When perlite ore is expanded by exposure to rapid, controlled heating, it grows up to 20 times its original volume and takes on a foam-like cellular internal structure — essentially clusters of microscopic glass bubbles. This physical transformation makes expanded perlite an extremely efficient, low ...

بیشتر

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. This makes perlite a very low-density material that is light-weight, with low thermal conductivity values.

Expanded perlite is formed when normal pyrite is heated. Heating perlite to a range of 1,560-1,650 °F (850-900 °C) causes the mineral to soften. As it does, the water that's trapped in the volcanic glass vaporizes and tries to escape. This causes the glass to expand to 7-16 times its original volume, and the remaining trapped air changes ...

As stated above in the first segment, bulk density of the ore/rock is one of the basic criteria requirements that should be included for proper apron feeder sizing. Density is the weight of material in a given volume, and usually bulk density is measured as tons/cubic meter (t/m³) or pounds/cubic foot (lbs/ft³).
