Vertical mixers (nauta mixer, conical mixers): 1, Working Principle: The screws of the Vertical Double Screws Mixer are rotating along the self-axes meanwhile revoluting along the central axes of conical container, so it is also called planet conical mixer. There are 4 working forms in the cylinder: A, rotating: Raise material along the helical blades. B, revoluting: Bring the material to run in circle in the container. C, rotation combined with revolution can make material absorbed by screw and dispersed by centrifugal forces effect. D, upgraded material fall down because of gravity, the materials move up and down, and inter-diffuse, convect with each other from full orientation space in the mixer. 2, Specification: (See the Table) 3, Discription: The special screw structure in the nautamixer is fit to mix the high viscous materilal. The centre screw and the out ribbon cooperate forming the up and down material flow. 4, Motor and decelerator: Three types of decelerator: Cycloid decelerator, worm gear decelerator, cycloid compound deceleration unit. (the normal type is cycloid decelerator). There are respective differences between the three types, so the choice of the decelerator depends on the application and customers requirement. The performance-to-price ratio of Cycloid decelerator is high. Worm gear decelerator can realize the rotation and revolution respectively, first rotation and then revolution. The performance of the cycloid compound deceleration unit is steady to satisfy the serious requirement of full-loading revolution. 5, Raw material: Carbon steel, manganese steel and SS steel(304, 316L, 321). Choosing the suitable raw material will down the cost. 6, Sprinkling/spraying system: When the liquid need to be added, we design the sprinkling or spraying system, which include nozzle and pipeline. There are types of nozzles, respectively different in shape, effect, current capacity. We can choose the suitable nozzle according to the different requirement. 7, Special full-loading: The nauta mixer structure can satisfy the rigor requirement of high density and high friction coefficient. 8, Installment: Suitable installment of nautamixer can guarantee the convenient operation and clean production area.
