Ross HDM 40 Gallon Double Planetary Mixer

Ross HDM 40 Gallon
Double Planetary Mixer


A non-vacuum Ross HDM-40 Gallon Double Planetary Mixer was modified for a client that was interested in having a vacuum-rated unit. A reinforcing ring was welded to the drive bonnet for mounting of a new vacuum hood, and all critical surfaces were machined. The right angle gear reducer and a new 15 HP motor were installed on the drive bonnet.


All bearings, gaskets, O-rings, and seals were replaced in the planetary gearbox. The original gearbox had lip seals, however, we installed new mechanical seals to ensure vacuum integrity. The original non-vacuum dust hood was replaced with a new vacuum-rated hood.
