Mixer company ROSS has released the DPM-150 double planetary mixer for mixing high-viscosity materials.
The firm said the new mixer has a unique agitation system and is heavy-duty, being able to process formulations ranging from 20 to 150 gallons and viscosities over 6 million centipoise. It is one of several production models being used in thousands of pharmaceutical, aerospace, adhesives, sealants, composites, and specialty chemical manufacturing plants globally.
The DPM-150 uses stainless steel type 304 wetted parts which the firm said are polished to a 220-grit finish. It has a vacuum mixing capability up to 29.5″Hg, and interchangeable mix cans to improve productivity.
The DPM-150 mixer is built for installation in a Class I, Division 1 and Class II, Division 1 hazardous locations. It has two stirrer blades with a bottom crossbar that are driven by a 40HP motor, which can be rotated between 7-27rpm on their own axes, at the same time as the mixer that has its own variable speed control with orbital speeds between 6-25rpm. ROSS revealed that the blades were X-ray analysed to ensure structural integrity, welds, and product contact surfaces were tested with dye penetrant.
The firm said the reverse lift system of the mixer has a stationary upper structure with a motorised hydraulic lift that raises the mix can to the mixing position. It gives an approximately 36″ clearance between the casters and floor when fully elevated.
The safety system includes automatic speed reduction to 6 inches per minute when the bowl approaches the vacuum hood interface.
The mix can each include a heating/cooling baffled jacket rated for 50 PSIG, sidewall-mounted thermocouple, and fully flush 6 inch “Y” discharge valve with no dead space.
