In the method in which combustibles are mixed and the medium lump (particle size: about 10 to 40 mm) is directly introduced into the separator 2 of the wind separation method to separate the non-burnable lump and the combustible, the non-burnable lump and the combustible are separated. Is not sufficiently separated, and wood debris, paper debris, and the like are mixed in the incombustible lump. Therefore, the combustible-containing non-combustible lump and sediment sorted by the conventional method cannot be collected and reused (for example, used as a backfill material for a structure) and disposed of for landfill. I have no choice. In addition, when transporting construction waste to the final disposal site (landfill), the introduction of a prior consultation system may result in the inability to dispose of non-combustible aggregates and sediment containing wood chips, paper chips, etc. doing.

About 5mm or less with 5mm or less earth and sand
m are separated into combustible materials and combustible materials, so that combustible materials such as paper chips and wood chips hardly enter the earth and sand. However, since combustibles such as paper chips and wood chips are mixed in the incombustible lump of 5 to 10 mm, the incombustible lump of 5 to 10 mm is further introduced into a specific gravity difference sorter. In this specific gravity difference sorter, combustible materials such as paper chips and wood chips are separated from non-combustible lump materials, so that non-combustible lump materials of 5 to 10 mm containing almost no combustible materials can be collected.
