Engineered for applications requiring advanced mixing capabilities, the ROSS VMC-300 combines three independently driven agitation systems in one unit.

This multi-shaft mixer integrates anchor, high-speed disperser, and axial flow turbine technologies to effectively manage complex and viscous formulations in the pharmaceutical, food, cosmetic, coatings, adhesives, composites, and other specialty chemical industries.

Constructed with stainless steel type 316 product contact parts, the VMC-300 has a 300-gallon working capacity and operates under full vacuum up to 29.5″ Hg and internal pressure up to 15 PSIG at 300°F.

The flat-bottomed mix can includes a jacketed sidewall and bottom rated for up to 140 PSIG for heating and cooling. The vacuum cover includes multiple ports, including a sight glass window, LED tank light, RTD temperature probe and various process connections.

The three-wing anchor agitator spins at 36 rpm with a 30 HP explosion-proof motor, featuring heavy-duty triangular cross-section design with helical flights and hinged Teflon scraper assemblies that wipe the vessel surfaces systematically.

The high-speed disperser reaches speeds of up to 1,150 rpm with a 50 HP explosion-proof motor and features two 10″ disperser blades for efficient powder wet-out and dispersion. Lastly, the high-speed axial flow turbine system uses a 50 HP explosion-proof motor to drive two 14″ three-blade turbines for intense blending and circulation.

The dual post lift system has a 10 HP electrohydraulic power unit and pneumatic lift locks to automatically secure the mixer in the fully raised or maintenance positions. Additional safety features include proximity switches that stop the drive operation when the vacuum cover is lifted, or when the mixing vessel is not in the proper mixing position.

The control system contains a 12″ color touchscreen for monitoring and adjustment of agitator speeds, loads, product temperature, vacuum level, and cycle timer. Variable frequency drives ensure precise speed control for all three agitators, while status indicators show mixer lift lock status and vessel placement. The explosion-proof electrical system is pre-wired for Class I Division 2 hazardous locations and includes safety interlocks.
