There, sized unexpanded perlite grains are fed in vertical furnaces where they are expanded to form lightweight perlite cellular bubbles. This special granular lightweight product is afterwards mechanically (e.g. through dry or wet mixing) or otherwise incorporated into the various end-products. Typical Applications of Perlite 1.
Details
An unexpanded perlite ore polishing composition is shown. The composition comprises base material having grains of unexpanded perlite ore of a selected distribution of particle sizes which undergo fracturing of the grains as a function of an abrasive force applied to the base material.
Details 
It is when perlite ore grains are abruptly exposed to immediate heat near to the sufficient temperature of their softening point (of 850° C) that the combined water rapidly vaporizes causing them to expand between 2-30 times their original volume.

XRPD analysis of native perlite (top) and expanded perlite (bottom). by expansion in industrial vertical expansion furnaces. In order to obtain the maximum expansion at this grain size (0.2–0.5 mm), are represented by α-quartz (26.67°) and cristobalite (21.94°).

Perlite is considered to be one of nature's most efficient and versatile minerals. It is a type of glassy volcanic rock form that is made up of a unique chemical composition and crystalline water content. It is when perlite ore grains are abruptly exposed to immediate heat near to the sufficient temperature of their softening point (of 850 ...

Expanded perlite consists mainly of cellular grains of high internal porosity. Waste expanded perlite contains mainly broken pieces of latter. Grains are irregular in shape and of low bulk density. During grinding cellular microstructure of WEP grains is destroyed and very thin and fine flaky grains are being formed.

Details 
Activity of expanded perlite is changing substantially with increase of disintegration of its microstructure. Grinding of typical bulk materials (like for example unexpanded, raw perlite) does not allow to obtain such fine and flat grains. This is why results obtained for ground expanded perlite are better than those for unexpanded one.

Details 
Our unexpanded perlite undergoes an extremely accurate screening process allowing for a low percentage of material outside the specified grain sizes. Furthermore due to suction undergone by our ore in the production process through multiple cyclones the final product has a remarkably low percentage of the undesired ultra-fine minerals.

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, suitable "as ceramic flux to lower the sintering temperature", and a commercial product useful for its low density after processing.
Details 
Unexpanded perlite production involves the mining, crushing and screening of perlite ore. It is the most common form demanded, given the convenience of its compressed volume for shipment. Most buyers will then expand the product at their own facilities making significant savings on transport costs.
