Conical Screw Mixer, also famous known as Nauta Mixer, consists of a conical shape vessel, top drive unit and screw agitator. The Nauta conical screw mixer is a batch mixer, specially designed for segregative, free-flowing powders and pastes. It is famous for its low-intensity mixing. It is particularly suitable for mixing delicate products and processes that require very precise results. Nauta mixers are available in volumes ranging from 300 to 12,000 liters.
The Nauta conical screw mixer is a convective mixer with high mixing efficiency. It is gentle and guarantees the highest level of mixing accuracy without product distortion. The rotating, cantilevered (free-hanging) mixing screw conveys the product from the bottom of the vessel to the product surface. The mixing screw is suspended from an orbital arm, which rotates the mixing screw along the conical inner vessel wall, causing convective mixing of particles and shear.The speed of particles in the downward mass flow, when recirculated by gravity in a conical vessel, increases as the vessel diameter decreases. The result of these simultaneous actions is a fast and intensive mixing with low consumption of power together with high standards of mixing accuracy.
The standard conical spiral mixer has two mixing screws. In practical applications, single (one long screw), double (one or two asymmetric screws of each length), and three (two short and one long symmetrically arranged) screws can be used according to the size of the equipment specifications; In theory, the more stirring spirals, the better the mixing effect.
Material can be carbon steel, manganese steel, ss304, 316L, and 321; different materials can also be used in parts, between the part in contact with the raw material and the parts that don't have contact with the raw material. Surface treatment for stainless steel can be sandblasting, wiredrawing, polishing, or mirror polishing.
The double screw conical mixer can be equipped with a jacket outside the mixer barrel according to process requirements, and cool or heat the material by injecting cold and hot media into the jacket. Generally, industrial water is pumped for cooling, and heating can be carried out by steam or electric heating of heat transfer oil.
The driven unit and power are varied according to different raw materials, starting methods, and processing.The double screw conical mixer is equipped with an appropriate double output reducer, which combines pinwheel, gear, and warm and gear.
The spherical valve or plum-blossom dislocation valve is matched to the double screw conical mixer. The surface of the valve matches the track of the bottom of the screw, to reduce the mixing dead zone to the maximum, and to make the largest discharging area, so as to make sure no leftovers. A spherical valve has an excellent sealing effect on powder, liquid, and even in a negative pressure state. Plum-blossom dislocation valve is easy to operate and controls the discharging speed.
1. The conical cylinder is suitable for the high requirement of no residue in the mixture.
2. Suitable for materials with significant differences in specific gravity and large powder particles;
3. The stirring speed during the mixing process is gentle and does not compress or crush the material particles;
4. It will not cause overheating of heat-sensitive materials; The stirring effect of this machine has a better coordination effect on the chemical reaction of materials
5. In the process of powder mixing, it is very convenient to add the liquid required by working conditions or set one or more spray port devices;
6. The bottom misalignment valve is convenient for discharging, and since there is no fixed device at the bottom of the screw, there will be no pressure-feeding phenomenon.
