Wood pellet machine mature development has been the focus of social concern, along with our country social economy development, urbanization brings to our social prosperity and the improvement of life quality improvement, but also brought a lot of garbage. When we advocate recycling economy and environmental protection today, junk flood already is an indisputable fact that, according to statistics, China's urban life rubbish annual output is about one hundred million tons and increasing by 9% a year. Therefore, the effective treatment of urban living garbage is an urgent task.
           Wood pellet machine will city life garbage into combustible waste solid fuel RDF, is the foreign developed countries more mature garbage disposal French, Japan, South Korea and other countries have already widely used RDF fuel power generation or heating. Production RDF fuel production process is, first by mechanical means will waste classification, according to the different material properties, can recycled part separate during, should go through magnetic separation, wind separation and nonmetals screening procedure, will waste of waste plastics, FeiZhiXie, sawdust, PVC and combustible waste separation out, after screening, crushing, drying, grinding, molding, formation of harmless granular fuel. Due to the RDF under high temperature extrusion curing become granular, in the manufacturing process of sterilization, facilitate storage may also directly to the power generation. RDF fuel made for chalk shape, diameter 15 ~ and mm, length of about fifty mm, water control at around 10%, close to the calorific value of coal, and can be widely applied in garbage power plant, cement plant, all kinds of industrial boiler, etc.

           In the face of growing city life quantity of refuse, the traditional booth pie type waste landfill method will be faced with increasingly "shrink", nowhere landfill dilemma; And now the widespread use of primary waste incineration power generation method, was the part of the social public questioning and dispute, the garbage "digest" problem is imminent. May be out of a suitable for China's national conditions of garbage disposal road still need a long time, this is a large and long social engineering, from the source of waste classification and reduction, to the garbage terminal diversified comprehensive disposal method (biological treatment, RDF, clean burning, a small amount of landfill, etc.), needs the government, enterprises and the public to make common efforts.
