When the crushed ore is exposed to high temperatures (around 850°C to 900°C), this water content vaporizes, causing the perlite to "pop" like popcorn. This expansion can increase its volume by up to twenty times, resulting in the lightweight, white, porous material we recognize as expanded perlite.

Expanded or unexpanded granular ore forms of perlite are added to molten metal pouring ladles. Most often the ore form is used which reacts slag in the ladle to allow easy removal of the slag layer. In cases where it is desirable to maintain a metal temperature in a ladle, the expanded perlite layer forms an efficient insulating blanket.

The perlite ore is shipped in 100 ton sealed railcars (Figure 4) to keep it from becoming wet and heavy. On average, forty-to-fifty of the 100-ton sealed cars are shipped per week. The perlite is usually shipped while unexpanded to cut down on shipping costs. Since perlite expands 40-50 times in size, it becomes uneconomical to ship from ...

Crude perlite is mined using open-pit methods and then is moved to the plant site where it is stockpiled. Figure 11.30-1 is a flow diagram of crude ore processing. The first processing step is to reduce the diameter of the ore to approximately 1.6 centimeters (cm) (0.6 inch [in.]) in a primary jaw crusher. The crude ore is then passed through a ...

Processing. Raw perlite ore is crushed, dried, screened and then heated at temperatures ranging from 1600° F to 1800° F. When it pops like ...

Perlite is a mineral ore which originated from the hydration of natural volcanic lava for over million of years. When Processed and heated up to 800⁰ - 950⁰ it will expand 4-20 times the original volume, Perlite becomes porous particles due to the release of water contained and thus reducing its density. Since the development of the Perlite ...

Perlite is a generic name for an amorphous volcanic alumina–silicate rock that expands by a factor of 4–20 when rapidly heated to 1400–1800 °F (760–980 °C). Both the ore and the expanded product have extensive and widespread commercial applications. Limited data on the toxicology of perlite in animal studies indicate that the LD 50 ...

Perlite is a fully natural, inorganic and chemically inert material, with little to no crystalline silica content by volume. It is derived from naturally occurring volcanic rock which mainly consists of amorphous silica (i.e. volcanic glass). From a regulatory standpoint, perlite is regarded as a ''nuisance dust".

Perlite furnaces are orientated vertically to facilitate sorting of the particles at different stages of expansion. The ore particles are fed into the furnace mid-way up the furnace barrel and levitate in a powerful stream of forced hot air heated to 900-1,000°C (1,800-2,000°F) by a combination burner and blower fixture at the base.
