Biomass molded fuel preparation system

The utility model relates to a biomass molded fuel preparation system, which consists of a material feeding opening, a scalping machine, a chipper, a grinder, an air heating furnace, a drying machine, a lifting machine, a permanent magnet barrel, a buffer recycling bin, a storage bin, a material feeding machine, an additive distributor, a granulator, a cooling tower, a packing machine, a vibration classifying screen, a buffering bucket, a dust removal device, a scraping plate conveyor, a belt conveyor, a spiral conveyor, a dust remover and a cyclone. By the preparation system, agriculture and forestry wastes are used as biomass raw materials, are subjected to processes such as grinding, extrusion, drying and the like and are prepared into granules or rod-shaped granules through special molding equipment; and the granules have the energy density which is about ten times that of unprocessed materials, are convenient to transport and store and have high combustion efficiency. The system is also provided with a plurality of dust removers so as to effectively reduce air pollution. An automatic packing machine is used for molded fuels so as to realize full-automatic production.
