VERMICULITE is the name given to a group of hydrated laminar minerals which are aluminium-iron-magnesium silicates, resembling mica in appearance. CRUDE VERMICULITE consists of thin, flat flakes containing microscopic layers of water. EXFOLIATION On being subjected suddenly to high temperatures (700°C to 1000°C) vermiculite flakes will
VERMICULITE. Vermiculite is used in the construction, agricultural, horticultural and industrial sectors. At Sun Silicates, we exfoliate Vermiculite in our natural, gas-fired plant. This ensures a top quality, sterilised product. When subjected to heat, Vermiculite has the unusual property of exfoliating or expanding into worm-like pieces.
Compact exfoliate vermiculite machine. Green 2000 developed a compact exfoliate vermiculite machine. The machine can be used as "in house" exfoliator easily. Any seedlings nursery or exfoliated vermiculite user can produce from now his own self fresh, clean and high quality vermiculite. The machine output is about 1,000 liter per hour.
Vermiculite is a naturally-occurring mineral composed of shiny flakes resembling Mica. It is produced in different grades or sizes. When heated to high temperature, vermiculite flakes expand 8-30 times their original size (a process called exfoliation) and loses weight.

The exfoliation of apparently pure true vermiculites that contain no potassium can also be explained by a mosaic structure, consisting of vermiculite and chlorite, achieved by nothing more than a switch in the nature of the interlayer from hydrated exchangeable cation interlayers in vermiculite to brucite-like interlayer hydroxide in chlorite.
Vermiculite undergoes significant expansion and exfoliation when heated above 870° C. The exfoliation process occurs when the water flashes into steam and the flakes expand. This exfoliation effect is normally produced in large commercial furnaces, and the resulting lightweight material is chemically fire resistant and inert.
Palabora vermiculite is a hydrated phlogopite mica which has the remarkable ability to expand to many times its original volume when heated, a property known as exfoliation. Being non-combustible and insoluble in water or organic solvents, vermiculite is safe and easy to handle, making it suitable for a wide range of different applications.
The exfoliated Vermiculite for Swimming Pool lining concrete is also used in the construction industries today and has wide applications, one of them being used as an additive to fireproof wallboard. It is a lightweight aggregate for plaster, proprietary concrete compounds, firestop mortar, and cementations spray fireproofing.
Mandoval Vermiculite is the only vermiculite company in South Africa that complies with International Code ISO 9001:2008 in manufacturing. Like most mined products there always is a certain amount of grit contamination. The Mandoval process of exfoliation ensures the majority of this grit is removed.
Vermiculite is a member of the phyllosilicate or sheet silicate group of minerals. It has the remarkable ability to expand to many times its original volume when heated - a property known as exfoliation. The term exfoliation is used to describe the heat expansion of the vermiculite, which occurs at right angles to the strong basal cleavage.
over 1500° F, causing the vermiculite to expand or "exfoliate". The expanded vermiculite would be conveyed to a stoner machine that would separate the product from any unexpanded vermiculite or "waste rock" .
