Cone Blenders, 18″ to 42″ Diameter Cones
Sepor cone blenders are manufactured with all contact parts made of stainless steel. Standard configuration of the cone blenders includes a variable speed control, a V-belt drive, shaft mounted speed reducer or gear motor, mild carbon steel stands with 18 inches of floor clearance, butterfly type discharge valve, gasketed load opening plate secured by a crossbar with hand wheel, heavy duty pillow block shaft bearings and normal electrical configurations of 110V V/1Ph/50-60 Hz or 220 V/1 Ph/50-60 Hz. The mixing vessel is comprised of two opposed cones, welded to a cylindrical center band. The center band has two oversize machined trunnions, 180 degrees apart, welded to it to provide an axis about which the vessel rotates. The angle of the cone is 45 degrees. The size in inches of the cone blender indicates the diameter of the center band of the mixing cone.
Blending in a cone blender occurs by slowly rotating the cone, where the angle of the bottom cone becomes tilted beyond the angle of repose of the material in the blender. Multiple surface layers then flow towards the empty cone, followed by the remainder of the material, in mass, to the empty cone end. The cone shape pushes a portion of the material towards the center, and upwards, where blending takes place. The shape of the mixing cone ensures that all particles travel in random directions, and all of the particles have different velocities as they travel from end to end resulting in rapid blending inside of the vessel. Ten minutes will generally give a homogeneous mixture.
Sepor Cone Blenders are excellent for blending of dry and semi-dry products. A wide variation of material types may be effectively blended, obtaining reproducible results. Over blending cannot occur. The Cone Blender will effectively blend fibrous materials and powder or granular materials.
Sepor Cone Blenders are easy to operate, with ample feed and discharge openings, easily cleaned between batches and are economical. Power costs are very low and no operator attention is required while blending is in process.
