Charles Ross Streamlines Design for Double Planetary Mixer

Especially designed to accommodate high-viscosity mixing, a new double planetary mixer from Charles Ross & Son Co. (Hauppauge, NY) eliminates the product overflow that can occur with typical double planetary mixers that are equipped with rectangular-shaped paddles.

According to the company, during mixing of especially viscous materials, product can “climb” typical rectangular-shaped paddles and out of the mix vessel. (The paddles typically move material by rotating the blades on their own axes while they orbit on a common axis.) This leads to reduced mixing efficacy, increased cleanup, and increased contamination risks.

The Ross planetary mixer instead features an updated helical blade design that the company says prevents the “climbing” issue experienced with traditional rectangular stirrers. The high-viscosity HV blades feature a precisely angled helical contour that generates a unique vertical mixing action. The sweeping curve firmly pushes batch material forward and downward, keeping material within the mixing zone at all times.
