Inner Mongolia Qian Feng Graphite Industry Company is located in Wuchuan County the Eastern part of Qilian Mountain . It has the advantages of convenient transportation network with 120KM distance from Huhe Haote City Inner Mongolia and 40KM from railway and 130KM from airport respectively . Formerly Qian Feng Graphite Industry Company was the state-owned graphite mine in Wuchuan county with 30 years history of graphite powder mining and processing . In 1996 the state-owned company have been reformed in system and merged by Qian Feng Company . For the time being it has the fixed assets of RMB26 millions . The total employee members are 368 with senior and medium level engineers of 38 . It has the superior natural graphite resources of large flake with deposit-exploited up to 20m tons , all of which are the superior sulphur-free graphite resource with 5% of 32mesh flake , 20% of 50mesh flake , 20% of 80mesh flake , 15% of 100mesh flake and about 60% of plus mesh flake . All these are the perfect resource for production of high-purified and expandable graphite . Based on the current mining scale of 5000MT annually the deposit could be mined for 50 years . With the superior resource as the raw materials and the advanced process of dressing , floating ,purifying and ultra grinding , we can produce various grades of graphite with FC from 85-99.99% and size from 500-0.5um . The graphite with special requirements of moisture , ash , size distribution and remains percentage on or below sieve applying in battery , electrical brush , graphite dag etc .could be processed accordingly .

Expandable graphite：

    Expandable graphite is one kind of flexible graphite products that is made through the special modification of the flake graphite materials . It's the perfect sealing materials that is widely adopted as dynamic and static sealing materials in petroleum , chemical , electricity , aviation , automobile , ship-making and instruments industry etc .
    Through the treatment at high-temperature at instant time the flaky form of expandable graphite will change into creep form with volume expanded to 100-400 times . The expandable graphite still remains the properties of natural graphite and has the properties of good ductility , flexibility and sealing . It's the superior materials for various kinds of graphite sheet and sealing parts and also could be used as protective slag and heat generator .
