The ROSS Double Cone Tumble Blender (Model DCB) is designed for large-scale yet intimate blending of free-flowing solids in a full suite of laboratory, pilot and production sizes. In a highly repeatable process, minor and micro ingredients are thoroughly distributed throughout the batch more gently than in the more common V-shaped geometry without damaging fragile or sensitive components. Rated for vacuum up to 29.5"Hg, the jacketed 75-cubic foot Double Cone Blender (Model DCB-75, below) heats and dries product with superior efficiency as it is being blended. Other features include gas purging capability, a 16” pneumatically-operated discharge valve, 5-passage rotary union, explosion-proof brake motor and PLC controls.
