Abstract
A dynamic mixer in which two elements are rotatable relative to each other about a predetermined axis and between which is defined a flow path extending between an inlet for materials to be mixed and an outlet. The flow path is defined between surfaces of the elements each of which surfaces defines a series of annular projections (8, 12) centred on the predetermined axis (10). The surfaces are positioned such that projections defined by one element extend into spaces between projections (12) defined by the other element. At least one cavity is formed in each projection (8, 12) to define a flow passage bridging the projection in which the cavity is formed. Each of the elements may be generally conical althrough each of the elements could be generally cylindrical or planar, providing projections in the two elements overlap.
