What does ROSS LPD & LLPD Static Mixers do?
The LPD and LLPD (Low Pressure Drop) ROSS models consist of a series of semielliptical plates which are discriminately positioned in a tubular housing, up to 40" in diameter or larger. A single LPD element consists of two plates perpendicular (or 120° for the LLPD) to each other and the mixing operation is based on splitting and diverting input streams. Both designs are most often used for turbulent product flow patterns.
How do ROSS LPD & LLPD Static Mixers work?
The ISG consists of individual mixing elements that are stacked in a tubular housing. As the product moves through each LPD element, flow is continuously split into layers and rotated 90 degrees in alternating clockwise and counterclockwise directions. This method of subdividing the flow and generating striations results in a highly predictable and repeatable mixing strategy commonly employed for high flowrate, low viscosity applications. During turbulent flow, the mixer elements enhance the random motion of molecules and formation of eddies. Four or six elements are usually sufficient for most low viscosity applications.
Technical Data
Ross LPD/LLPD (low pressure drop) and ISG (interfacial surface generator) Motionless Mixers are well known for their wide ranging uses in turbulent and laminar flow mixing applications. Each design can be supplied as complete plug-in modules or as individual elements for installation into your preferred housing design.
