IPC: B41M5/26
Filed: 1991-12-25
Abstract: PURPOSE:To combine various processes of separating media from a material moisture dispersion liquid efficiently and crush the material in a wet state using fine media so that the material is crushed further to finer particles. CONSTITUTION:The micro space bite of a media separator are limited to 0.025 to 0.150mm, and the average diameter of the medium is limited to 0.05 to 0.30mm, when a material moisture dispersion liquid 4 is stirred with a crushing medium 3 and crushed to be separated using a medium separator.
