Activated Carbon Regeneration Rotary Furnace
In 1985, China National Gold Group Corporation was approved by theNational Economic Council,it decided
to introduce foreign advanced technology and equipment to conduct a technological reformation in Tongguan and Zhangjiakou gold mine. United States daiweimaiji company was responsible for the basic design, Changchun Gold Research Institute provided the technical support , introduced the first set electric-heated rotary kiln Activated Carbon Regeneration furnaces of gold industry in China.
In May of 1987 ,it was put into operation, and also has carried on the digestion of technology and domestic equipment reservation.In 2002 , we started to develop JHR-O series fuel oil heated active carbon regenerating furnace, August of 2004, it was put into practice in Zhang jiakou Gold mine of Hebei.In 1997 ,we also developed the JHR series electric heated active carbon regenerating furnace,in 2007, technology was upgraded and we also applied for patent of electrical ( gas ) heating rotary kiln for activated carbon regeneration equipments, gas prices rose dramatically in 2010, JHR-E series electric heating rotary kiln for active carbon regenerating furnace became the main force again.
