Perlite originates from volcanic glass formed when obsidian, a natural volcanic glass, cools rapidly. Water attracts to the rock, causing it to change over time into perlite ore, a glassy volcanic rock with a 2-5% moisture content. 3.How is Perlite Harvested? Through a mining process, workers harvest perlite.

Use perlite to aid drainage. Succulents and other plants sensitive to moist soil benefit from having perlite added to the potting compost. The perlite will trap air in the compost and encourage water to …
Perlite Beneficiation Process. Perlite, as required for the light weight aggregate industry, must be closely graded and the amount of minus 100 and minus 200 mesh perlite must be closely controlled. …
Therefore, it should first be ineffective water content in the expansion of perlite to go away, and it needed to retain the normal expansion of the water (ie effective moisture). After extensive tests summarized and laboratory and production plant, the effect of perlite expanded processing plant effective water content is between 2.2-2.4% ...
Basic characteristics of perlite. Perlite is a naturally occurring volcanic glass containing 70-75 % silicon dioxide SiO2 and 2-5 % water Н20.The water content is a crucial factor for the specific properties of this mineral. …
For more than forty years, the perlite industry has been at the forefront of testing for health effects that may be associated with the production, processing and use of raw and expanded perlite. Initially, much of the industry research effort was sponsored by the Perlite Institute, an international trade association founded in 1949 by perlite ...
The drying process is carefully controlled to keep from overheating the ore and driving off the "combined" moisture which allows the perlite to expand when heated to final temperature. The crushed ore is processed through a series of screens with successively smaller openings, sorting it into various grades and sizes.
Nature: The result of rapidly heating raw perlite to temperatures above 2000°F (1093°C), causing the glass structure to soften and the water trapped within to vaporize, expanding the particles. Color: White or light gray, due to the reflection of the internal bubbles. Texture: Lightweight, porous, and popcorn-like. The expansion can increase its volume by 4 to 20 …

Find out if you should be adding perlite to your houseplant soil, or if there's something else you should be using! 2.75M; 1.25M; 2.85M; 1M; ... Drainage holes are a vital part of this process as the water needs somewhere to go, but the drainage levels in the soil are also important. ... one part perlite and one part coconut coir to improve ...
Save time and resources with Norlite perlite insulation. For over 45 years, this innovative insulant has helped customers avoid wasting material and time in the application process. Plus, it is an environmentally-friendly choice, with Nordisk Perlite recycling production heat as district heating for over 1000 s in the neighboring ...
During processing, the raw Perlite obtained from the ground is heated rapidly to temperatures of 1560°F to 1650°F, causing the moisture inside the volcanic glass to vaporize. ... You can prepare a …
The perlite you see in hardware stores and garden centers is expanded perlite. While crude perlite has no use in gardening, it is a widespread material in masonry construction and insulation. Most of the world's perlite comes from New Mexico, Utah, and Oregon, but there are also large mining projects in parts of Eastern Europe, China, and …
Perlite's important natural property is the ability to expand when rapidly heated at temperature of 800°C-950°C. The abrupt, controlled rise of the temperature when we heat perlite causes the formation of white minuscule glass bubbles. Perlite mets, expands and attain an extremely porous surface, increasing its volume by 10-14 times.
