ROSS Unveils Custom Coaxial Mixer for Complex Formulations
This custom-built mixer has a 1,100-gallon working capacity, engineered for full vacuum operation to 29.5" Hg, and internal pressure up to 15 psig at 300 °F. Image courtesy of ROSS.
Through an innovative concentric-shaft configuration, this advanced system effectively blends, disperses, and homogenizes materials by combining two synergistic agitation technologies. In a variety of industries, including adhesives, sealants, coatings, and composites, the coaxial design enables processors to handle a wide range of rheologies while offering a range of different flow patterns.
The agitation system consists of two independently driven components: a heavy-duty design two-wing anchor with triangular cross-section and a pitched-blade propeller assembly. Both agitators are each powered by a 15 HP explosion-proof motor, with the outer agitator producing speeds up to 25 rpm, while the inner shaft turns the propellers up to 191 rpm. The NEMA 12 control panel has two 15 HP VFDs built in with ethernet/IP option for controlling each agitator either locally or remotely; displays for speed, amperage and percent load, an Emergency Stop button, and the appropriate safety disconnects.
This custom-built mixer has a 1,100-gallon working capacity, engineered for full vacuum operation to 29.5" Hg and internal pressure up to 15 psig at 300 °F. The fixed cover includes multiple access ports including a hinged manway with safety limit switch. Product temperature is controlled via heating/cooling media passing through a two-zone stainless steel half-pipe jacket on the sidewalls and bottom, ASME stamped for 100 psig at 300 °F. A 4” pneumatic flush tank ball valve facilitates a smooth discharge process.
