Abstract
A homogenization method particularly applicable to fuel oil containing water and/or coal dust is described. Ideal homogeneity is achieved by supplying the substances to be homogenized between cooperating surfaces one of which is afforded by the internal circumferential surface of a homogenization chamber and the other of which is afforded by the external circumferential surface of the first of a coaxial stack of discs whose edges are cylindrical or are part-spherical, causing the substances to cross the path of rolling of the discs so as to cause disintegration of a phase or phases insoluble in the liquid or one said liquid between the discs and said circumferential surface in the region of the point of the rolling engagement as the substances pass under gravity down through the homogenization chamber and withdrawing the homogeneous liquid obtained from the other end of the chamber beyond the path of rolling movement of the discs, the discs being unrestrained mechanically against movement towards and away from the internal surface of the chamber throughout their rolling motion and the pressure between them and the chamber surface being produced solely by centrifugal force.
