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.

Development of Graphite Mining in Africa:
The government policy has developed a growth strategy for its Graphite Project in Tanzania that envisages a staged development that can produce up to 100,000 tonnes per annum of concentrate.
Production will commence at 40,000 tonnes annually with ramp up to 100,000 tonnes over two stages offering the company the ability to respond quickly to future increases in demand.
Since in 2008, we had start export Graphite Rotary Dryer to Africa , which is uesed in Graphite Mining and selection and cleaning and purify.


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.
