Summary: | PROBLEM TO BE SOLVED: To continuously and efficiently produce fine particle with a prescribed particle size or smaller by jetting a liquid with high pressure into a slurry-state liquid in which an object to be crushed is suspended. SOLUTION: A jetting hole 2 is opened in a container 1 in which a slurry state liquid is to be poured and a liquid 4 supplied from a pressure generating source 3 such as a pump is jetted to the slurry-state liquid. The particle in the slurry-state liquid is crushed by shearing force in a jet current shearing layer induced by jetting the liquid 4 at high pressure and also by impact pressure due to cavitation generated in the slurry-state liquid in the container 1. Since the volume of the liquid in the container 1 increases by continuous supply of the liquid 4 in such a manner, the supply of the liquid 4 is stopped in a stage that a prescribed amount of supply is completed and the resultant fine particle which is a crushed product in the slurry-state liquid in the container is taken out. In order to take out the fine particle, a method of sorting by a sorter or evaporating the liquid is employed and the remaining particle is taken out. |
