Built to handle a wide range of formulations and viscosities, the ROSS FDA-50 Fixed Tank Dual Shaft Mixer is a custom-design agitated pressure reactor ideal for processes that require meticulous control over mixing, temperature, and pressure in a compact and portable module. The stainless-steel type 316 dished bottom vessel and removable dished cover can accommodate internal pressures up to 100 psi, stamped according to ASME Section VIII, Div. I. 

The mixer/reactor is equipped with two agitators. The high-speed disperser features two 6” sawtooth blades — one fixed at the bottom and one adjustable along the shaft. It is driven by a 5 HP explosion-proof motor up to 1760 rpm, creating a vortex into which dry ingredients can be delivered for fast wetting. The disperser is belt-driven with removeable drive motor, belt and guard. The two-wing anchor agitator is direct-driven by a 5 HP explosion-proof removable gearmotor up to 45 rpm, designed with a heavy-duty triangular cross-section and removeable Teflon sidewall scrapers. The anchor feeds product towards the high-speed disperser blades and ensures that the batch contents are never stagnant in any one area. Dry-running single mechanical seals compatible with various solvents are utilized on the mixer shafts. All product wetted surfaces are polished to 320 grit finish.

The FDA-50 also includes a 2” flush tank discharge ball valve with a sanitary outlet connection, and an assortment of sanitary inlet ports on the cover. The mobile mixer stands on four splayed stainless-steel legs with foot pads and non-marking urethane casters—two rigid and two locking—for stability and easy movement.
