Two basic-No Moving Parts- Motionless Mixer designs are offered for use in turbulent and laminar flow mixing applications.
The ISG (interfacial surface generator)consists of individual mixing elements that are stacked in a tubular housing. The ends of the elements are shaped so that the adjacent elements form a tetrahedral chamber. Four holes bored through each element provide the flow paths. The holes are at oblique angles so that material near the periphery (i.e. near the pipe wall) on the inlet side of the element emerges near the center on the outlet side. The material exiting one element then enters near the center into the second element and exits near the wall. This radial mixing eliminates the wall smearing effect that can be otherwise encountered when mixing viscous materials.
