A Brief introduction about Graphite:
Graphite is a crystalline form of carbon, a semimetal, a native
element mineral, and one of the allotropes of carbon. Graphite is
the most stable form of carbon under standard conditions.
Therefore, it is used in thermochemistry as the standard state for
defining the heat of formation of carbon compounds. Graphite may be
considered the highest grade of coal, just above anthracite and
alternatively called meta-anthracite, although it is not normally
used as fuel because it is difficult to ignite.
Uses of natural graphite:
Natural graphite is mostly consumed for refractories, batteries,
steelmaking, expanded graphite, brake linings, foundry facings and
lubricants.[Graphene, which occurs naturally in graphite, has
unique physical properties and is among the strongest substances
known. However, the process of separating it from graphite will
require more technological development.
Graphite Rotary Dryer is our major product, so professional technology support and
all-around service can be offered to you.
Graphite Rotary Dryer is handling by bringing it into direct contact with a heated gas.
The dryer is made up of a large, rotating cylindrical tube,The
dryer slopes slightly so that the discharge end is lower than the
material feed end in order to convey the material through the dryer
under .
Working principle of the Graphite Rotary Dryer:
Material to be dried enters the dryer, and as the dryer rotates,
the material is lifted up by a series of internal fins lining the
inner wall of the dryer. When the material gets high enough to roll
back off the fins, it falls back down to the bottom of the dryer,
passing through the hot gas stream as it falls. This gas stream can
either be moving toward the discharge end from the feed end (known
as co-current flow), or toward the feed end from the discharge end
(known as counter-current flow). The gas stream can be made up of a
mixture of air and combustion gases from a burner, in which case
the dryer is called a direct heated dryer. Alternatively, the gas
stream may consist of air or another (sometimes inert) gas that is
preheated. When the gas stream is preheated by some means where
burner combustion gases do not enter the dryer, the dryer known as
an indirect-heated type. Often, indirect heated dryers are used
when product contamination is a concern.
Features of Graphite Rotary Dryer :
1.reasonable structure,
2.high efficiency, low energy consumption,
3.convenient for transportation,
4.convenient and reliable operation;
Except the Single Drum Rotary Dryer, our company also can offer you
the triple way rotary dryer to drying the graphite, which had the
advantage of small place occupation, and energy saving.
