ГУММИРОВАННЫЙ РОТОР БИСЕРНОЙ МЕЛЬНИЦЫ

摘要

FIELD: fine grinding of hard materials in liquid phase. ^ SUBSTANCE: bead mill's rotor has shaft with gummed discs put onto it and distance sleeves. External cylindrical surface of sleeves is coated with layer of rubber. Elastic longitudinal protrusions are made together with cylindrical surface. Protrusions have cross-section in form of isosceles triangle. Sides of triangle are outlined by smooth convex curves. ^ EFFECT: higher degree of dispersion of initial material; prolonged service life of rotor. ^ 2 cl, 2 dwg
