Abstract
A method and device for producing a finely divided dispersion of solids having a mean particle size of 10 nm to 10 µm, in which at least two flows of a predispersion are sprayed by means of pumps, preferably high-pressure pumps, through one nozzle each into a grinding chamber enclosed by a reactor housing onto a collision point, wherein the grinding chamber is flooded with the predispersion and the finally divided dispersion is removed from the grinding chamber by the overpressure of the predispersion continuing to flow into the grinding chamber.
Claims8
A device for producing a finely divided dispersion, comprising:
- at least two nozzles for spraying a predispersion, at least two pumps, wherein each of said nozzles have an associated pump, and a grinding chamber surrounded by a reactor housing, wherein the predispersion is fed onto a common collision point and the dispersion leaves the minding chamber through an opening in the reactor housing wherein the collision point in the device is surrounded by balls.
