摘要： A process and a high pressure apparatus are disclosed which are useful in preparing magnetic dispersions and other dispersions of hard, non-compliant particulates. The apparatus can be monitored for clogs and wear and allows for relatively quick and inexpensive replacement of orifices. The apparatus includes a high pressure pump and a series of impingement chambers comprising an input manifold where the process stream is split into two or more streams and an output manifold where the streams are recombined after passing through restrictive orifices configured in such a manner that the streams impinge on each other at high velocities. The orifices in each succeeding impingement zone are the same size or smaller than the orifices in the preceding impingement zone, and the orifices in the final impingement zone must be smaller than the orifices in the first impingement zone.
