Production of Ferrite Granules According to the Vacuum Hot Steam Process (VHSP)

H. Dürr
Abstract : For the granulation of ferrites according to the vacuum hot steam process (VHSP) a high-pasty material is used as starting material. Homogenizing and dispersing of the mixing components are made in an intensive mixer with rotating mixing pan and high-speed rotor by using high shearing forces. Granulation is made by drying. Superheated steam is passed through the material as drying medium under vacuum. The adjustment of the granule size can be reproduced. The granules are distinguished by an increased density, considerably improved homogeneity, higher abrasive resistance, homogeneous moisture distribution in the interior.
