A conical screw mixer consists of one or more screw agitators revolving and rotating along the wall of a conical vessel. The blending screw lifts the material and deflects it towards the center from where it moves down again. The choice of a suitable mixer depends on the physical state of the ingredients, filling and discharge methods, batch volume, and the tolerable shear level. Conical screw mixers are ideal for low shear mixing of pharmaceutical powders and pastes. They are also suited to mixing shear-sensitive products in the food, plastic, metals & minerals, nuclear and chemical industries.
