METHOD OF GRINDING CELLULOSE-CONTAINING PRODUCTS Russian patent published in 2002 - IPC

FIELD: solid organic material grinding equipment. SUBSTANCE: method involves exposing cellulose-containing products to preferably compressive loads created by rolling multiplicity of milling bodies of rotation over product to be ground, with bodies of rotation contacting with curvilinear supporting surface of grinding apparatus housing; grinding cellulose-containing product under high-speed mode while repeatedly applying compressive loads at time intervals between loading cycles not exceeding 0.025-0.030 s and number of repeated loading cycles upon product to be ground by means of milling bodies of rotation during passage of said product from upper inlet channel to lower outlet channel of at least 30-40 times. Shear loads created simultaneously with compressive loads make 1.5-15% of compressive load value. Said product is also exposed to superhigh frequency current. EFFECT: increased efficiency and improved quality of ground cellulose- containing product. 6 cl, 7 dwg
