COLLISION CRUSHING METHOD AND COLLISION CRUSHING SYSTEM USING THE COLLISION CRUSHING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a collision crushing method and a collision crushing system capable of performing superior crushing even when a crushing object is a granular body having a comparatively small size and further reducing energy required for crushing.;SOLUTION: When a jet flow j is jetted toward a target 120b from a jet nozzle 10a and a granular crushing object X introduced to a target 10b accompanying the jet flow j collides with the target 10b and is crushed, the collision crushing method executes: a preliminary step forming a crushing object-bonded granular material Cx by bonding the crushing object X on the surface of a granular body C having a larger mass than the crushing object X; and a crushing step introducing the crushing object-bonded granular material Cx formed in the preliminary step to the target 10b accompanying the jet flow j from the jet nozzle 10a and colliding with the target 10b.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2018,JPO&INPIT
