Abstract
Abstract A pair of pressure cylinders are located in axial alignment, separated by a nozzle body through which at least one duct passes. Operating pistons move the composition of matter to be treated from one cylinder into the other, the composition being forced through the duct or ducts of the nozzle body. The ducts of the nozzle body have a cross section which is noncircular and may include a constriction so that flow through the duct or ducts will be at essentially uniform speed over its cross section to improve mixing and wall contact of individual elements of the substances passing through the duct or ducts. The nozzle body is clamped in position between the cylinders by a releasable compression element, for example, hydraulically operated; a release or lifting pressure jack is provided to separate the cylinders, when desired, so that the nozzle block can be easily removed.
