METHOD FOR PRODUCING TRANSPARENT DIOXAZINE PIGMENTS

摘要

The invention relates to a method for producing transparent dioxazine pigments. Said method is characterised by the use of an eccentric oscillating mill to crush a dioxazine crude pigment, said mill comprising at least one milling container that is mounted on the oscillating elements and an excitation unit that is rigidly fixed to said milling container. According to the invention, the excitation takes place in an eccentric manner on one side, outside the gravitational axis and the centre of mass of the milling container, thus generating inhomogeneous oscillations consisting of circular, elliptical and linear oscillations.
