Ross unveils new mixing system

The two mixers are mounted on a common base and are connected with piping to facilitate continuous circulation of materials until the desired dispersion is obtained.

A built in control panel enables precise control of all agitator speeds, amperage and run times.

The availability of software insures that the desired results are achieved repeatedly, batch after batch.

The PowerMix consists of two Hi-Viscosity Planetary stirrers, two High Speed Dispersers and a scraper to wipe the sides of the vessel.

The variable speed (11-110 rpm) planetary blades are driven by a 1-1/2 HP motor, while the variable speed (900-9000 rpm) high speed dispersers are driven by a 3 HP motor.

The separate high shear rotor-stator mixer is driven by a 1 HP variable speed motor, for operation up to 10,000 rpm.

All wetted parts of the system are made of 304-stainless steel and finished to a 320 grit finish to enable easy cleanup between batches.

The system is built for vacuum operation to 29.5" Hg and features a vacuum pump.

The mix vessel is jacketed for 50 Psig and consists of a thermocouple to monitor batch temperature. It also consists of a convenient discharge valve to discharge the materials on completion of the batch.

Additional sizes, ranging from 2-gallon design to 750-gallon production sizes, are available.
