of arrow 7008 fluids passing between said rotating discs 7030 and 7028 are thereby exposed to very high shear furthermore fluids become mixed continuously at high speed and are unable to stratify or escape the high shear and severe blending conditions between said discs 7030 and 7028 conduit 7012 can be connected directly with a suitable valve and pumping arrangement with flow regulators maintaining a suitable pressure in the space between rotating discs 7030 and 7028 and enclosure 7010 fluids therefore are able to react during the time they are enclosed between said rotating discs and before transferring into the enclosed space within enclosure 7010 through radial slots such as 7036 said discs 7030 and 7028 can be held together by mechanical pressure with contact restricted by ridges such as 7019 and 7018 the apparatus shown in fig7 can be arranged with multiple pairs of discs corresponding with multiple parallel rows of apertures such as 7034 and 7029 in this way manifolds may be arranged for example within boss 7006 and 7020 such that streams of materials and fluids can be transferred between each pair of plates such that a quantity of fluid transferred through conduit 7002 will be transferred into the space between each pair of discs and correspondingly fluids transferred through conduit 7024 can also be transferred between each set of rotating discs in a similar fashion to the description herein such.
