NOVELTY - Device comprises a first frame (100) installed with a hopper installing stage, a hopper (200) inserted into the hopper installing stage, a first crusher (300) for producing first debris by crushing branches and leaves, a first conveyor (400) for moving the first debris crushed by the first crusher, an infrared dryer (500) for drying the first debris with infrared rays, a second frame, a second crusher for producing second debris by finely crushing the first debris, and a second conveyor for moving the second debris discharged from the second crusher.    USE - The device is useful for manufacturing fuel pellets using branches and leaves (claimed).    ADVANTAGE - The device recycles waste resource and so is environmentally friendly.    DETAILED DESCRIPTION - Device comprises a first frame (100) installed with a hopper installing stage, a hopper (200) inserted into the hopper installing stage, a first crusher (300) for producing first debris by crushing branches and leaves supplied from bottom side of the hopper, a first conveyor (400) for moving the first debris crushed by the first crusher, arranged in inclined manner, an infrared dryer (500) for drying the first debris with infrared rays, provided on upper side of the first conveyor, a second frame provided on opposite side of the first frame, a second crusher for producing second debris by finely crushing the first debris received form the first crusher by dropping from the first conveyor, coupled to upper surface of the second frame, and a second conveyor for moving the second debris discharged from the second crusher, arranged at lower space of the second frame. The first crusher is connected to a gear with a drive shaft and a driven shaft, where the drive shaft and the driven shaft are coupled to several rotary cutters at regular intervals. The rotary cutter of the drive shaft and the rotary cutter of the driven shaft are formed staggered. The rotary cutters coupled to the drive shaft and the driven shaft, are differently formed with a cutter blade between the rotary cutters. The second crusher has a case having lower case and upper case formed with a slot on upper side and rotatable against the lower case, a rotating shaft, and several module holders formed axially, provided with several holders protruding at regular intervals circumferentially coupled to outer surface of the rotating shaft, where the module holders are fitted with hammers and connected by hammer pins.
