DSH series nauta conical screw mixer is a convective batch mixer which is specially designed for segregative, free-flowing powers and pastes. It is famous for it's low-intensity mixing and highest level of mixing accuracy without product distortion.
The basic design consists of two cylindrical screws located at the vessel wall that conveys product from the bottom of the conical vessel to the product surface. The twin-screw is attached to an arm which rotates around the perimeter of the vessel causing convective mixing and shear. The speed of particles in the downward massflow when recirculated by gravity in a conical vessel increases as the vessel diameter decreases. The three actions result in a unique three dimensional mixing action.
DSH series nauta conical screw mixer is widely used in food, chemical and pharmaceutical industry for:
1) Mixing and homogenization of powders, pastes and slurries
2) Granulation or agglomeration of powders
3) Addition or injection of liquids into dry powders
4) Heating and cooling of powders
