A recent innovation has stirred up a lot of excitement in many industries that rely on high viscosity mixers - the new Ross DPM Double Planetary mixer. Equipped with Ross's new HV Blades, the new mixer can replace a double-arm kneader in many applications, cut operating costs substantially, and increase production

Double planetary mixers have generally been considered appropriate for mixing materials up to approximately 1.5 million centlpoise. Double-arm kneaders have traditionally handled the heavy stuff,such as highly filled adheslves, heavy silicone and butyl sealants, and bulk molding compounds.

But a double-arm mixer commands about three times the price of a double planetary mixer, requires more space on the plant floor, and Introduces many potential problems with shaft seals and packing glands submerged in the product zone.

The double-arm unit generally operates with more horsepower and consumes more energy than a double

The new,streamlined DPM Double Planetary Mixer offers a variety of standard features and options that make It the most powerful, efficient and convenient double planetary mixer ever built,

The standard model includes self-contained, pre-wired controls, variable speed Inverter drives, and completely

planetary mixer. Because of Its horizontal orientation, it also cannot be supported with a set of interchangeable mix vessels - an option that often elevates double planetary mixing to a semi-continuous process.

Anyone who has watched fumed silica float on the surface of a liquid batch has seen a great opportunity to cut processing costs. Even when generating a strong vortex in a vessel with a turbine or high speed disperser, powders such as fumed silica, calcium carbonate, titanium dioxide, gums or thickeners still resist wetting out. They can float like soap suds on the surface for 15 minutes, an hour or even longer - pushing up costs and holding down production

Ross's new In-line rotor/stator mixer with Solid/Liquid Injection Manifold (SLIM) technology can simplify powder induction and shorten mixing cycles significantly. The mixer is equipped with Progressive Spiral Porting and a unique rotor/stator generator that creates a vacuum strong enough to draw solid additions directly into the high-shear zone and eliminate surface float. With excellent control over the Inlet flow, the In-Llne SLIM system is

capable of adding a high volume of powders to the stream.

The new In-Line SLIM system can also reduce "dusting" - and the risk of potentially hazardous particles airborne In the plant atmosphere. When lightweight powders are poured into a vessel or hopper, they often release a cloud of dust Into the air. This can present a serious respiratory hazard for the operator and others in the plant. In significant concentrations, It can also be explosive. Adding powders with the SLIM vacuum injection system virtually eliminates this risk, since few particles become airborne.

The In-Llne SLIM can be coupled to an existing mixing system of virtually any size -and only when It is needed to Introduce solids quickly. Once the solids have been
