NOVELTY - Apparatus comprises a main body (1) provided with an input port to introduce waste, and a discharge port to discharge water and foreign matter, a first foreign material separation unit (2) to separate water and waste containing foreign material, a cylindrical first screen (3) provided with multiple through holes to discharge water and foreign material separated by first foreign material separation unit, a second foreign material separation unit (4) for separating water, foreign material and waste by cutting waste and cylindrical second screen (5) provided with multiple through holes.    USE - The apparatus is useful for removing foreign material by dual crushing-manner (claimed) to produce highly pure combustible fuel.    ADVANTAGE - The apparatus increase amount of flammable substances, and is easy to maintain.    DETAILED DESCRIPTION - Apparatus comprises a main body (1) provided with an input port for introducing waste on upper side, and a discharge port for discharging water and foreign matter separated from waste to lower side, a first foreign material separation unit (2) for removing water, and waste containing foreign material by hitting injected waste via the input port, provided inside the main body at upper portion, and rotated at a high speed, a cylindrical first screen (3) provided with multiple through holes for discharging water and foreign material separated by the first foreign material separation unit, located outside of first foreign material separation unit, a second foreign material separation unit (4) for separating water, foreign material and waste by cutting the waste which is dropped from the first foreign material separation unit, it rotates at a high speed, and spaced apart on same vertical line with the first foreign material separation unit, a cylindrical second screen (5) provided with multiple through holes for discharging water and foreign material separated by the second foreign material separation unit, located outside of second foreign material separation unit, and a foreign material discharging unit for discharging water and foreign material separated from waste to the outside, located in bottom of the main body.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic representation of the apparatus for removing foreign material by dual crushing-manner.    Main body (1)    First foreign material separation unit (2)    First screen (3)    Second foreign material separation unit (4)    Second screen (5)
