Benefits of choosing a ROSS High Speed Disperser. What does a ROSS High Speed Disperser do? The cost-effective saw-tooth disperser is a standard workhorse in the production of chemicals, polymers, composites, inks, paints, adhesives, food products and a variety of other applications.  Its major purpose is to incorporate powders into liquid and break down particle agglomerates to generate a fine stable dispersion. How does a ROSS High Speed Disperser work? The open disc blade of the high speed disperser, which travels at roughly 5,000 feet per minute, is designed to induce vigorous turbulent flow within a low viscosity batch. It creates a vortex into which dry ingredients can be poured for fast wetting. The blade speed may be changed as the batch thickens or increases in volume to maintain the vortex and rate of material turnover. To avoid "stratification" or possible layering inside the batch, most models allow the disperser to be raised and lowered during mixing.

Benefits of Choosing a ROSS High Viscosity Disperser: What does a High Viscosity Disperser do? High-Viscosity Dispersers, also known as Bow-Tie Mixers are low shear devices used for paste-like substances and other dense and/or viscous applications. In lieu of a Bow-Tie, a Paddle Blade Agitator can be supplied for handling a wider range of viscosities. How does High Viscosity Disperser work? The bow-tie-shaped agitator is particularly efficient at slow speed high viscosity paste mixing and generating a flow pattern that keeps even dense particulates uniformly suspended. At the same time, the mixing process helps to prevent abrasive wear caused by hard particles.

Benefits of choosing a ROSS Laboratory High Shear MixerWhat does a ROSS Laboratory High Shear Mixer do? Perfectly designed for research and development, the ROSS Laboratory High Shear Mixer is ideal for reducing the size of agglomerates and droplets in fine dispersions and emulsions to create scalable, highly repeatable products. How does a ROSS Laboratory High Shear Mixer work? The Laboratory High Shear Mixer design consists of a single stage four-blade rotor that turns at high speed within a stationary stator. As the rotating blades pass each opening in the stator, they mechanically shear particles and droplets, and expel material at high velocity into the surrounding mix, creating intense hydraulic shear. As fast as material is expelled, more is drawn into the bottom of the rotor/stator generator, which promotes continuous flow and fast mixing.

Benefits of choosing a ROSS Batch High Shear MixerWhat does a ROSS Batch High Shear Mixer do? The ROSS Batch High Shear Mixer is ideal for reducing the size of agglomerates and droplets in fine dispersions and emulsions to create scalable, highly repeatable products.

Benefits of choosing a ROSS/AMK Kneader ExtruderWhat does a ROSS/AMK Kneader-Extruder do? ROSS/AMK Kneader Extruders combine the efficiency of a double arm - sigma blade mixer with the convenience of an extrusion screw for the mixing and discharging of heavy viscous materials exceeding 10 million cP. These machines are used throughout the chemical, pharmaceutical, plastic, coating, ink, paint, adhesive, composite, and food product industries in the manufacturing of highly viscus, thick and very sticky products such as silicone rubber, putties, printing ink, oxide ceramics, hard metals, and marzipan. How does a ROSS/AMK Kneader Extruder work? The Kneader Extruder includes a set of counter-rotating kneading blades and a discharge screw. The blades are mounted on a horizontal axis in a U-shaped trough. Below the blades in a separate cavity is the discharge screw.
