Product Details
Graphite is a soft, steel-gray to black, hexagonally crystallized
allotrope of carbon with a metallic luster and a greasy feel,
used in lead pencils, lubricants, paints, and coatings, that is
fabricated into a variety of forms such as molds, bricks,
electrodes, crucibles, and rocket nozzles. Sophie is an extremely
soft mineral at 1 to 2 on Mohs’ hardness scale. It is black and
has a black streak. Its softness and streak make graphite useful
in making “lead” for pencils. Crystals are uncommon, but when
they occur, they are found as rough, six-sided (hexagonal)
flakes. This feature is the cause of graphite’s distinctive
greasy feel. It is this greasy characteristic that makes graphite
a good lubricant. Because it is a solid material, it is known as
a dry lubricant. Graphite is the only non-metal element that is a
good conductor of electricity. In nature, graphite is found in
two distinct forms, flake graphite and lump graphite. Lump
graphite is more compact than flake and lacks the distinctive
flaking mentioned earlier.
1. Importance will grow with green technologies
2. Up to 10x more graphite in a li-ion battery than
lithium
Demand will outstrip supply
3. Just for one market – EV cars – demand by 2020 will require
more than is produced globally today.
4. Then you’ve got the electronics market and nuclear
energy.
uses
Because graphite flakes slip over one another, giving it its
greasy feel, graphite has long been used as a lubricant in
applications where “wet” lubricants, such as oil, cannot be used.
Technological changes are reducing the need for this
application.
It is also used to make brake linings, lubricants, and molds in
foundries. Graphite
vertical machine
is professionally processing fine and superfine powder of
non-inflammable, non-explosive and brittle materials with Moh's
hardness under six, the moisture under 5% such as calcite, chalk,
limestone, dolomite, kaolin, bentonite, talc, mica, magnesite,
illite, pyrophyllite and vermiculite, sepiolite, attapulgite,
rectorite, diatomite, barite, gypsum, alunite, graphite,
fluorite, rock phosphate, Kalium ore, pumice, etc., totally more
than 100 kinds of materials.
Finished graphite powder fineness: 47-5 micron
(325mesh-2500mesh)
Capacity: 0.4-12T per hour
Models graphite vertical
machine:
HGM80/HGM90/HGM100/HGM100A/HGM125
Working principle:
1) After crushed by hammer crusher, the large materials become
smaller pieces and are sent to the micro powder grinding
mill.
2) When the micro powder grinding mill is at work, the granulated
materials are crushed and grinded by the rollers into particles
below 47micron.
3) The high-pressure air blower constantly inhales air within the
micro powder grinding mill.
4) Along with the high speed airflow, micronized materials are
brought to the classifier.
5) The qualified particles are screened and driven into the
cyclone powder collector, finally exit from the discharging valve
at the bottom;
6) A small proportion of the fine powders, with airflow, moving
to the dust cleaner. Filtered clean air will be emitted from the
air outlet of muffler in the end.
