High-speed disperser HSD series

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. Design - ROSS High Speed Dispersers are truly a heavy-duty design. They are equipped with inverter-duty TEFC or explosion proof motors up to 500HP, heavy duty V-belt drives and bearings, an air/oil hydraulic lift, high-quality laser cut blades and stainless steel wetted parts. These machines are built to last. Scalability – ROSS High Speed Dispersers are available from bench top laboratory models to very large production models capable of dispersing several thousand gallons at a time. Flexibility - The design of the ROSS High Shear Disperser allows for containers of various sizes (diameter and height), as well as their placement on or off center. The shaft is used as a baffle in off-center mixing. This reduces or collapses the vortex which minimizes air entrapment in the batch.
