APPARATUS FOR MANUFACTURING DRY POWDER FROM WASTE

PURPOSE: To provide an apparatus for manufacturing a dry powder from a waste in which fuel cost can be largely reduced and even if a large waste or a relatively hard material is mixed, it can be effectively comminuted to a power. CONSTITUTION: A first region 38 is formed at the upper site and a second region 52 is formed at the lower site in a housing 10. A large ball 40 for comminuting a waste by natural drop is continued in the first region, and small balls 54 for comminuting the waste by the natural drop are contained in the second region, and a feeding means 12 is disposed in the housing. The large ball is fed from the lower site to the upper site in the first region to drop the large ball from the upper site to the lower side in the first region, and the small balls are fed from the lower site to the upper site in the second region to drop the small balls from the upper side to the lower site in the second region. Oil tubes 16, 18 are placed in the housing, oil heated by a heating means 24 is circulated, and the large ball and the waste in the first region and the small balls and the waste in the second region are heated.
