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, 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) stopping the at least one impeller for a maximum time T, characterized in that T is calculated according to the following relations: u T = 4 g ρ p − ρ f D p 3 ρ f C D C D = 24 Re 1 + 0.173 Re 0.657 T = h u T with u T = terminal velocity in the vessel for particles with average diameter D p, g = gravitational constant, ρ p = particle density in the slurry, ρ f = density of the liquid phase of the slurry, D p = average diameter of the particles in the slurry C D = drag coefficient, Re = Reynolds number, h = pre-determined height (e.g. vessel height); wherein the at least one impeller has a vertically upper end with respect to the vertical axis of the at least one impeller and a vertically lower end with respect to the vertical axis of the vessel and wherein the stopping of the at least one impeller is continued until the level of the slurry is within a range from 0.1* D a (diameter of the impeller) to 0.05* D a below the vertically lower end of the impeller. (a) providing a vessel comprising at least one impeller rotating around a vertical axis of the vessel, 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) stopping the at least one impeller for a maximum time T, characterized in that T is calculated according to the following relations: u T = 4 g ρ p − ρ f D p 3 ρ f C D C D = 24 Re 1 + 0.173 Re 0.657 T = h u T with u T = terminal velocity in the vessel for particles with average diameter D p, g = gravitational constant, ρ p = particle density in the slurry, ρ f = density of the liquid phase of the slurry, D p = average diameter of the particles in the slurry C D = drag coefficient, Re = Reynolds number, h = pre-determined height (e.g. vessel height); wherein the at least one impeller has a vertically upper end with respect to the vertical axis of the at least one impeller and a vertically lower end with respect to the vertical axis of the vessel and wherein the stopping of the at least one impeller is continued until the level of the slurry is within a range from 0.1* D a (diameter of the impeller) to 0.05* D a below the vertically lower end of the impeller. T is calculated according to the following relations: u T = 4 g ρ p − ρ f D p 3 ρ f C D C D = 24 Re 1 + 0.173 Re 0.657 T = h u T with u T = terminal velocity in the vessel for particles with average diameter D p, g = gravitational constant, ρ p = particle density in the slurry, ρ f = density of the liquid phase of the slurry, D p = average diameter of the particles in the slurry C D = drag coefficient, Re = Reynolds number, h = pre-determined height (e.g. vessel height); wherein the at least one impeller has a vertically upper end with respect to the vertical axis of the at least one impeller and a vertically lower end with respect to the vertical axis of the vessel and wherein the stopping of the at least one impeller is continued until the level of the slurry is within a range from 0.1* D a (diameter of the impeller) to 0.05* D a below the vertically lower end of the impeller.
