NOVELTY - This utility model claims one kind of biomass particle fuel production device, comprising a pre-processing device, a stirrer, a distributor, at least two pelletizer, a dust remover, a finished product, finished product belt machine and a finished product cabin, the pre-processing device of the material taking front end processing, wherein the pre-processing device comprises a feeding pit, wet belt machine, a cylinder sieve, insulating wind pipe, a drier, a cyclone separator and storage bin, the storage bin and the stirrer is connected with the pre-treated material stirrer to stir, the distributor to the material in at least two pelletizer for pelleting forming, from the biomass particle after screening dust, sieve finished product belt machine to the finished product. Compared with the existing technology, this utility model not only can process the biomass particle fuel with high quality, but also production efficiency is high and low failure rate.    USE - The device is useful for producing biomass pellet fuel (claimed).    ADVANTAGE - The device produces high quality biomass pellet fuel with high productivity.    DETAILED DESCRIPTION - The device comprises a pre-processing device, a stirrer, a distributor, at least two granulators, a dust collector, finished product belt conveyor and a finished product cabin. The preprocessing device comprises a feeding pit, wet belt conveyor, a cylinder sieve, insulating wind pipe, a drier, a cyclone separator and storage bin connected a stirrer. The granulator comprises a granulating mold, a main shaft and a pressing roller device. The main shaft and the pressing roller device rotates at 100 degrees C to press the granulating mold. The granulation mold comprises a protection plate and a mold core. The protection plate has a portion connected to the fixed shaft, having a groove to accommodate the protection plate. The mold core is formed with at least one group of pelleting holes, where the pelleting holes, at intervals, are provided with a circular ring.
