The new Ross Model HSM-100LH-3 Vacuum High Speed Disperser is designed for laboratory and pilot-scale mixing of batches up to 5 gallons. It can be supplied with a vacuum-rated mix vessel including a heating/cooling jacket and mixer cover with sight/charge ports. Interchangeable saw-tooth disperser blades are available (2-, 3-, 3.5- and 4-inch diameter), suitable for variable speed operation up to 4,800 rpm. All wetted parts are stainless steel type 316.
High Speed Dispersers are useful for wetting out solids and creating a uniform, air-free suspension or solution under vacuum. The classic open-style saw-tooth disc blade generates a vortex on the liquid surface into which powders and other minor components are added for quick incorporation. Rapid turnover and vigorous flow patterns are achieved throughout a wide range of viscosity: from water-like to around 50,000 centipoise.
The HSM-100LH-3 is driven by a 3HP VFD-rated motor. Safety limit switches prevent operation of the mixer while in the raised position or without a mix vessel in place. A 3HP inverter is mounted to the mixer and wired to the motor and limit switches for single-point electrical hook-up. The mixing head is raised by means of an air/oil hydraulic lift with pushbutton controls (requires 80 to 100 psig air source).
