General
- Vermiculite is a natural mineral
that expands with the application of heat.
- Vermiculite is formed by hydration
of certain basaltic minerals.
- Vermiculite is a 2:1 clay, meaning
it has 2 tetrahedral sheets for every one octahedral sheet.
- vermiculite is
a member of the phyllosilicate group of minerals, resembling mica in
appearance
Application
- Pressed vermiculite block
insulation can be used in high temperature kilns, furnaces, combustion
plants, boilers, wood burning stoves and night storage
heaters.
- Vermiculite for refractory and
high temperature insulation is normally bonded with alumina cements,
fire clays and silicates to produce a wide range of vermiculite products
which, depending on type and application can withstand hot face
temperatures of up to 1100ºC.
- Vermiculite is now used
extensively in the friction lining industry as a safe alternative to
asbestos, and plays an important role in this field.
- Vermiculite has found its
application as an ingredient of fodder at limited foddering of
poultry.
- In agriculture, vermiculite is
used as a sorbent, meliorant, fertilizer, radioprotector, and
mulch.
Process
- During the manufacturing process,
vermiculite is “popped” or “exfoliated” at high temperatures so that it
expands, releases water and forms a lightweight, fire–resistant
material.
- The dehydration process has been
shown to occur through different interstratified states in
each vermiculite.
- The manufacturing process used to
produce commercial expanded vermiculite consists of two separate
operations.The mining and concentrating operations that produce raw
vermiculite flakes are conducted at one location. The exfoliation and
classifying operations that produce various sizes of lightweight,
expanded vermiculite granules for use in other products are conducted in
another location
Market
- New U.S.Customer Due to a
combination of the market's need for stable supplies of quality coarse
grade vermiculite and IBI's increasing reputation as a reliable supplier
of such material, a number of new prospective customers have contacted
the Company and are now trying out the Company's...
- One way to illustrate the
growth-enhancing properties of vermiculite to potential customers is to
demonstrate it with plants grown in trial pots, some using soil enriched
with vermiculite and some using plain soil as a control.
- IBI’s customers reports that our
coarse grade Namekara vermiculite exfoliates well in the furnace when
processed at temperatures as low as 400 Degrees C compared with the
usual 800 Degrees C recommended for regular vermiculite.
