The ROSS FDA-50 Fixed Tank Dual Shaft Mixer is a custom-design agitated pressure reactor built to handle a wide range of formulations and viscosities. It is ideal for processes that require meticulous control over mixing, temperature, and pressure and comes in a compact, portable module. The design comprises a stainless-steel type 316 dished bottom vessel and removable dished cover that can accommodate internal pressures of up to 100 psi. The mixer/reactor is equipped with two agitators and has a high-speed disperser with two 6” sawtooth blades (one fixed at the bottom and one adjustable along the shaft), driven by a 5 HP explosion-proof motor that moves up to 1760 rpm. This speed creates a vortex into which dry ingredients can be delivered for fast wetting. The disperser is belt-driven and has a removeable drive motor, belt, and guard. In addition, the two-wing anchor agitator is direct-driven by a 5 HP explosion-proof removable gearmotor that moves up to 45 rpm. The agitator is designed with a heavy-duty triangular cross-section and has removeable Teflon sidewall scrapers. The anchor feeds product toward the high-speed disperser blades, ensuring that batch contents do not stagnant in any one area. The mixer shafts use dry-running single mechanical seals that are compatible with various solvents. In addition, all product wetted surfaces are polished to a 320-grit finish. This mixer/reactor also houses a 2” flush tank discharge ball valve that leads to a sanitary outlet connection. It also contains an assortment of sanitary inlet ports on the cover. The mobile mixer remains stable on four splayed stainless-steel legs with foot pads and non-marking urethane casters, two of which lock and two of which are rigid. The casters make it easy to move the unit around.
