Charles Ross & Son Company Planetary Dual Disperser Laboratory Mixer PDDM Series

Hybrid planetary mixers are utilized for creating fine dispersions in viscous mixtures, typically within the viscosity range of 100,000 to 2 million cP. Intense mixing is applied to the product by constantly advancing a high speed disperser and a low speed stirrer into the batch. Solids are quickly incorporated into the viscous bulk material and agglomerates are dispersed regardless of product flow characteristics.

Designs for multiple planetary stirrers and disperser blades are available for more demanding applications.

To date, ROSS has supplied over 2,000 of the model PDDM alone for process industries worldwide.

STANDARD FEATURES:

• Full vacuum change can design
• Vertical lift design (reverse lift) for raising of mix can to the operating position
• Integrated base design for mounting on table top or work bench
• Two (2) Rectangular Stirrers or High Viscosity “HV” Blades
• Two (2) High Speed Disperser Shafts and Blades
• Agitator drive components and lift system are fully sheathed
• Stainless steel type 304 wetted parts with 80-grit finish
• Non-stainless steel components are finished with a durable two-part epoxy coating
• TEFC 230/460 volt, 3 phase, 60 Hz motors
• Stainless steel gearbox with Viton sealing O-rings and lip seals on stirrer shaft, disperser shaft and upper gearbox cover
• Safety limit switch to prevent operation of the mixer when the mix vessel is not in the mixing position
