Title
(EN) PROCESS FOR PROVIDING A HOMOGENOUS SLURRY CONTAINING PARTICLES
(FR) PROCÉDÉ DE FOURNITURE D'UNE SUSPENSION HOMOGÈNE CONTENANT DES PARTICULES
Abstract
(EN)
The present invention is concerned with a process for providing a homogeneous particle-containing slurry comprising the steps of: (a) providing a vessel comprising at least one impeller rotating around a vertical axis of the vessel, wherein a rotational speed n1 of the at least one impeller is higher than nmin according to equation (1), the vessel further comprising an inlet and an outlet; (b) introducing a particle-containing slurry into the vessel or introducing components forming the particle-containing slurry into the vessel; (c) rotating the at least one impeller at least around the vertical axis for homogenizing and/or maintaining a homogeneous particle distribution within the slurry; (d) withdrawing the homogeneous particle-containing slurry via the outlet; (e) reducing the rotational speed n1 of the at least one impeller to a reduced rotational speed nred, whereas nred is lower than n1 and higher or equal than nmin according to equation (1):
