Visualize a filled fermenter with a variable speed agitator at rest with a Rushton turbine. Soderberg, in Fermentation and Biochemical Engineering Handbook (Third Edition), 2014 6.5 Comparison of Shear of Air Bubbles by Agitators and Jets Each input within the process must be added separately and only into mixtures that have been validated to contain the correct properties before mixing ensues.Allan C. A continuous dry mixing process like mulling foundry molding sand, requires sand, water, clay and coal dust to be mixed into a moldable plastic product. The complexity of dry mixing is largely based in the segregation, capacity and validation within the process itself. The extensive blending applications require a high level of functional experience, knowledge and process understanding. Modernly there is a range of industrial technologies used to improve product quality, fuse materials, wet, agglomerate and alter material properties to name a small few. Through a collective century of dry mixing experience, a global network of SPX FLOW testing centers and a depth of analytical technologies, SPX FLOW can design specialized dry mixing solutions. SPX FLOW blending engineers have the extensive experience to develop, predict and scale a specific mixing behavior. To reduce the energy cost of a solid suspension process, SPX FLOW engineers could design a multi-turbine mounted impeller shaft to efficiently reduce energy consumption. Large volumetric flow is recommended for solid suspension, however, high shear, high flow-number turbine impellers are not vital to the process. Solid suspension or solid to liquid mixing, often viewed as a high energy cost process, SPX FLOW industrial mixers can be designed to meet specified process needs. A tank with baffles will be able to rotate to convert the radial-flow impellers rotational motion into vertical motion to displace collected solids. However, radial-flow impellers used in conjunction with baffled mixing tanks can function similarly. Axial-flow impellers are typically suggested for solid suspension, especially when the solid is denser than the liquid within the solution.

The suspension of solids within an industrial mixing process improves the rate of mass transfer within the solution. An example of this process occurs in the mixing of concrete, where solutes, cement and sand, are mixed with the solvent and water to create a malleable yet self-hardening product. Liquid-solid mixing often requires the deconstruction of agglomerated solids, by suspending particles in the mixture then destabilizing bulks of solid material. Our custom process solutions are optimal industrial mixing technologies constructed to fulfill process needs and reduce operating cost through a mix of efficient design and aftermarket services. SPX FLOW application engineers develop customized mixing and blending solutions to the specific process needs of a customer.

SPX FLOW is a global leader in the research and development of energy-saving industrial solutions and custom process design. A poorly functioning mixing process can cause extended mixing times which can lead to a slowed process, decreased outputs, increased energy consumption and a higher cost of operation. Unoptimized mixing or blending process may lead to higher energy use and overarching operating cost. Any minor miscalculation in mixing performance could leave a noticeable effect on a production line’s end product. The sheer range of varying mixing needs makes finding the optimal mixing solution a challenge. Mixing and blending processes are present in manufacturing lines across modern industry.
