摘要

PROBLEM TO BE SOLVED: To obtain more minute dry ice fine particles D, D, ... by only assembling general facilities without using a special facility.;SOLUTION: An injection apparatus 1 having two injection nozzles 2 and 2 disposed to be faced each other so that the injection center lines L and L of respective injection holes 2a and 2a are matched is prepared. A plurality of dry ice particles D1, D1, ... having a Mohs hardness of 1.5 or more are injected at a high speed from the two injection nozzles 2 and 2 and collide with each other. The dry ice particles D, D, ... crushed by collision energy to be an average particle diameter of 0.3 mm or less are obtained.;COPYRIGHT: (C)2015,JPO&INPIT
