Abstract: A method of manufacturing a non-molded solid fuel using a combustible waste material includes (a) primarily crushing an inflowing waste material using a bag-tearing and crushing device, (b) separating iron from the primarily crushed waste material using a first magnetic sorter, (c) sorting the waste material, from which the iron is separated, according to the particle size of the waste material using a first oscillating multi-stage particle-size sorter, (d) secondarily crushing the waste material having a large particle size using an impact crusher, (e) separating the iron from the secondarily crushed waste material using a second magnetic sorter, (f) sorting the waste material, from which the iron is separated, according to the weight of the waste material using a wind power sorter, (g) separating the iron from a light material, and (h) pulverizing the waste material, from which the iron is separated.
