Title:
湿式媒体粉砕方法
Document Type and Number:
Japanese Patent JP7097938
Kind Code:
B2
Abstract:
To provide a wet medium pulverization method accelerating the pulverization of a material to be pulverized by preventing deterioration of a pulverizing power resulting from temperature rise in a pulverization chamber.SOLUTION: A wet medium pulverization method includes: agitating in a pulverization chamber 3, a mixture 13 of slurry of a material to be pulverized including a liquefied inactive gas such as liquid nitrogen 20 as a dispersant, and pulverization media such as balls or beads; pulverizing, crushing and/or dispersing the material to be pulverized by the above media. The method is characterized by feeding the liquefied inactive gas to the pulverization chamber 3 to lower temperature of the dispersant during agitation of the mixture 13, so as to maintain viscosity of the dispersant at a level which allows the media to pulverize, crush and/or disperse the material.SELECTED DRAWING: Figure 2
