Ross unveiled its ROSS V Cone Blenders that utilize diffusion as the main mixing mechanism, providing a high level of precision and consistency, it says. The V-shaped vessel rotates on a horizontal axis, causing batch materials to cascade down, distributing particles over a freshly exposed surface. With operating speeds of 5 to 25 revolutions a minute, the ROSS line of tumble blenders can easily mix dry solid blends, including high-density powders, low-viscosity slurries, friable materials and formulations containing trace components and/or ingredients that are dissimilar in size, shape and density, the company says. The ROSS Model VCB-20 is fully customized, with two pneumatic cylinders affixed to the V cone body, which disconnect and connect fiber drums for charging and discharging. A high-speed intensifier bar is installed along the mixer’s axis of rotation, which also supports nozzles for continuous liquid additions during the mixing process. A NEMA 12 Control Panel includes a 7-inch touchscreen for viewing and collecting the blender’s and intensifier bar’s rotational speeds. ROSS notes that the controls package includes a job function, emergency stop pushbutton, motor fuse protection, rotary disconnect and proximity switches. The proximity switches stop the blender at certain preferred positions and relay logic control for precise operation of the drum lift mechanism, it says.
