PURPOSE: To granulate melts contg. various materials surely by setting the inside diameter of a granulating device for radioactive waste, etc. at a constant inside diameter or larger and the number of revolutions of a rotary disc in a specific range.
CONSTITUTION: In a granulating device for radioactive waste, etc., a cylindrical body 22 in the upper part of a base frame 21 is formed to ≥1,000mm inside diameter, and a rotary disc 38 in the central part in the body 22 is set at 500W 1,300 numbers of revolutions per minutes. Sinc melts are accumulated at one time in the recess of the disc 38 by such arrangement, the melts of a uniform temp. can be scattered from the disc and are granulated surely despite the inclusion of various materials therein.
