The ROSS Double Cone Blender is a common workhorse used throughout the process industries for mixing powders and other free-flowing solids. This blender can heat, cool, or dry materials under vacuum. It can also coat solid particles with small amounts of liquid.
A ROSS Double Cone Blender features a rotating vessel comprising two conical sections and a middle cylindrical shell. Diffusion is the main mechanism for mixing: batch materials cascade down, distributing particles over a freshly exposed surface as the vessel rotates on a horizontal axis. Tumble blending is very low-impact and appropriate for processing abrasive solids and friable ingredients. It is also commonly used in making precise blends containing trace components or ingredients that are dissimilar in size and density. The geometry of the double cone vessel allows complete discharge of the blended material.
