Ross’ CDA-300 Dual Shaft Mixer Enables Accurate Processing for High-Performance Formulations

Ross’ CDA-300 Dual Shaft Mixer is designed to be a versatile, robust and cost-effective system engineered for accurate processing of high-performance formulations across a wide range of rheologies, solids loading, operating temperatures and pressures.

The mixer features two powerful agitators — a two-wing anchor agitator driven by a 20-hp TEFC high-efficiency, inverter duty motor and a high-speed disperser powered by a 60-hp TEFC high-efficiency, inverter duty motor. The open disc blade of the disperser, which travels at roughly 5,000 ft./min., is designed to induce vigorous turbulent flow. It creates a vortex into which dry ingredients can be poured for fast wetting. The anchor feeds product toward the high-speed disperser blade and ensures constant turnover, even as the batch gains viscosity.

The CDA-300’s change can design features an air/oil hydraulic lift that enables the use of multiple mix cans, which are constructed of stainless steel type 304 and include a heating/cooling jacket on the sidewalls and bottom for temperature control. A 3" manually operated stainless steel flush bottom ball valve with tri-clamp connection facilitates easy discharge, while casters enable easy movement around the production floor. Designed for vacuum operation, the Dual-Shaft Mixer produces air-free products with highly repeatable density, viscosity, composition and dispersion quality.

The NEMA 12 control panel is supplied with a 7" color touchscreen for user-friendly operation, providing independent agitator speed controls, load display, cycle timer and other functions. Safety features include NEMA 12 limit switches to prevent operation when the mix can is removed or the agitators are not in the mixing position.
