Customized blade designs and flow patterns to optimize the mixing process.
Industrial Mixing Equipment
Planetary Mixers
The Double Planetary Mixer, introduced by ROSS in the early 1940s, quickly became a standard workhorse for high viscosity mixing throughout the process industries. ROSS pioneered a series of design and engineering advancements over the decades, expanding the capabilities of the original Double Planetary Mixer to meet the world's ever-changing needs.
The introduction of High Viscosity Blades raised the maximum viscosity range to around 6-8 million cP. A number of applications that previously required horizontal sigma blade kneaders are now mixed in ROSS Double Planetary Mixers offering better cleanability, smaller footprint and lower capital cost.
Design Options
Double Planetary Mixer
Our High Viscosity "HV" blade design is ideal for mixing and kneading viscous pastes under atmospheric or vacuum conditions. The "HV" Blades each rotate on their own axes, and at the same time on a common axis, thereby providng complete mixing in a very short timeframe.
Powermix
The PowerMix combines a planetary blade and a high speed dispersion blade. Both agitators are in constant motion. The planetary and the high speed disperser blades rotate on their own axes and also rotate continuously around the vessel.
Planetary Dual Disperser
This unit is equipped with two helical planetary stirrers, one of which includes a bottom scraper. Two saw-tooth blades are installed on each high speed shaft. A scraper arm removes material from the vessel wall to ensure superior heat transfer during the mixing process.
Industries Served
Recommended Mixing Equipment for Dental Composites
Dental composites are synthetic polymers filled with reinforcing glass and/or ceramic particles.
A typical mixing procedure starts with blending two or more monomers often of significantly different viscosities. Various particle size fillers are then added to the liquid binder and mixed under vacuum until a homogenous paste is obtained. High amounts of fillers render most dental composites very abrasive. Initiators, inhibitors and pigments may also be added to the hardenable paste.
The first of its kind, Ross High Viscosity "HV" Blades (US Patent No. 6,652,137) feature a precisely angled contour which generates a unique mixing action: the sweeping curve firmly pushes batch material forward and downward, keeping it within the mixing zone at all times.
