The mineral graphite is one of the allotropes of carbon,for its use in pencils, where it is commonly called lead (not to be confused with the metallic element lead). Unlike diamond (another carbon allotrope), graphite is an electrical conductor, a semimetal. It is consequently, useful in such applications as arc lamp electrodes. Graphite is the most stable form of carbon under standard conditions. Therefore, graphite crusher 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 hard to ignite.
Graphite is mined around the world by both open pit and underground methods. While flake graphite and amorphous graphite are both mined open pit and underground, lump (vein) graphite is only mined underground in Sri Lanka. The open pit mines usually employ equipment (i.e. bulldozers) to scoop up the ore, which is usually put in trucks and moved to the plant. Since the original rock is usually lateritized or weathered, this amounts to moving dirt with flecks or pieces of graphite in it.
Graphite-containing refractories are sometimes also recycled, but often not because of their graphite: the largest-volume items, such as carbon-magnesite bricks that contain only 15–25% graphite, usually contain too little graphite. However, some recycled carbon-magnesite brick is used as the basis for furnace repair materials, and also crushed carbon-magnesite brick is used in slag conditioners. While crucibles have a high graphite content, the volume of crucibles used and then recycled is very small.Our Graphite Mining Equipments are used to process quartz , limestone , basalt, chrome , dolomite, feldspar, fluorite, kaolin ore, marble , granite , iron ore ,copper ore , sandstone, silica , gold ore , silver ore , lead ore , manganese ore , tin ore.
Graphite Crusher is widely used in graphite and ore crushing .Graphite stone is feeded into the Jaw crusher for primary crushing by the Vibrating feeder, then the bulk material is transfered by the elevator conveyor to Grinding mill for fine grinding, and finally the finished product is out of Grinding mill and it’s fineness can reach a range of 30 -2,500 mesh.
