WHAT IS NATURAL EMERY?
Natural Emery is a very
hard rock type used to make abrasive powder. It largely
consists of the mineral
oxide), mixed with other species such as the
magnetite, and also
Industrial emery may contain a variety of other minerals
and synthetic compounds such as
silica. However natural emery is mostly made of
brown Corundum and Emery are the most common forms of
Corundum. These are fairly common and when ground up,
they are the most favorable abrasives.
The industrial term "emery" describing
abrasives is derived from the variety Emery which is
mined for abrasive use
brownish-black or dark gray in color. It is the
hardest mineral after
making it the second hardest mineral
with a mohs hardness value of 9.
Crushed or naturally
eroded emery (known as black sand) is used as an
abrasive — for example, on an
emery board, as a traction enhancer in
tarmac mixtures, or as used in mechanical
engineering as Emery cloth.
AREAS OF USE
Coated Abrasives: Emery is widely
used in manufacturing of
coated abrasives like emery cloth & emery paper.
The typical self sharpening action of the emery grains with needle shaped grains and
uniform grading make emery grains the
first choice for use in this application.
Stones: Emery grains are mixed with the
magnesium oxide and magnesium chloride slurry
and allowed to set in a mould to form a solid
flour mill stone. Due to superior hardness,
emery grains help in better quality and durable
Sandblasting/Abrasive Blasting: Emery grain is the most suitable material
for sandblasting purposes. Emery is shot across a
surface at high speeds by pressurized machines. The
effect is similar to that of using
sandpaper, but provides a more even finish with no
problems at corners or crannies. Also unlike other
abrasive materials, emery grains have more than one
sharp edges on each particle. With this characteristic,
emery grains can be used more than once (usually
2-3 times) in a sandblasting operation. Please check the
emery picture above. Besides emery is non-hazardous for
human health, providing improved worker safety
Anti-Skid and Non-wear Flooring: Surfaces in
highways, shipyards and airports are under heavy
traffic. Emery is used on these surface to make them
more resistant. Either
with oxychloride formulation or with plain Portland
cement emery grains can be used as hard aggregates for
anti skid and non wear flooring. This type of flooring
is very useful in areas like warehouses with heavy
forklift traffic, workshops where oil is spilled and
heavy objects fall now and then, hospital ramps,
reception areas with heavy foot traffic, ship decks, and
treads of staircases and so on. Superior abrasive action
of the emery grains imparts better grip and resist the
wear caused by heavy traffic. At toll booths on
highways, such surface will provide good braking for the
vehicles and add as a safety feature.
Traction Enhancement: Emery is
commonly used in asphalt to enhance traction.
Polishing and Dehusking: Emery
grains along with magnesium oxide and magnesium
chloride are applied to the rice sheller cone ,
in rice mills for polishing rice with minimum
broken grains and faster output. The special
rice polishing grade emery grains form a
superior oxychloride bond and as a result the
stone lasts longer.
and Descaling: Metal parts sheared and cut
, left with unfinished edges can be deburred
with emery in minutes , by putting the
parts in barrels and tumbling them along with
coarse sized emery grains. Similarly
metal parts with rusty surface and salt deposits
can be easily cleaned.
Steel Polishing: Emery grains applied on a cloth buff is widely and
popularly used for polishing of metal articles
like automobile accessories (car bumpers, door
handles) , dinnerware and table ware ( bowls,
plates, knives, spoons, forks etc.) stainless
steel balls for ball bearings and innumerable
other stainless steel articles. The smaller
individual crystal size, higher corundum
content, and perfect sizing makes emery
the first and popular choice for Stainless steel
polishing. This product can also be used in form
of a emery compound or paste.
Production: Emery grains are popular among fire
brick producers for their high resistance and strength.
Lens Lapping: The finer grades ( 220 to
400 ) are used for lapping of optical lenses;
either in lieu of other abrasives or before and
after these abrasives.
