Rare earth is a total of 17 chemical elements in the periodic table of scandium, yttrium and lanthanide elements, and is a non-renewable resource. According to the different atomic electron layer structure and physical properties of rare earth elements, rare earth elements can be divided into light rare earth, medium rare earth and heavy rare earth. Light rare earths, also known as cerium group rare earths, mainly include lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium; Medium and heavy rare earths, also known as yttrium group rare earths, mainly include gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium. How does the rare earth mixing equipment mix evenly in trace elements such as rare earth materials? This depends on the process performance advantages of the mixing equipment.
Dual-power hybrid equipment used in the rare earth industry has the following characteristics:
1, adhering to the excellent advanced dual-power superposition mixing structure: the internal full-size mixing blade superposition the 360-degree movement of the external cylinder, the material powder without dead Angle rotation mixing shear mixing, to achieve high uniform mixing effect.
2, wide range of application, rare earth, high-tech materials, plastic particles, powder metallurgy, superhard, chemical, battery, construction, magnetic materials and other special.
3, the equipment model is complete, the laboratory is mainly used for 2-20L, the production is mainly used for 50-5000L, and the larger model can be customized.
Because rare earth belongs to trace elements, rare earth and other trace elements and more types, which is relatively high requirements for mixing, rare earth mixing equipment how to mix evenly? The advantages of dual-power hybrid equipment stand out among many hybrid equipment. The principle of the mixing device is to superposition the full-size rotating spiral belt blade in the rotating container, and in the same direction as the barrel, twice the speed of the barrel. In this way, the container and the leaves will bind the light powder floating above and press into the main weight powder, so that the light and heavy powder can be evenly mixed; Some manufacturers of traditional mixing equipment are also aware of this mixing principle, and want to change the light and heavy powder in the mixing process on the basis of the original traditional equipment to solve the problem that it is not easy to mix, such as adding rotating spiral blade in the traditional double-cone mixer; The modified double-cone mixing equipment can not solve the problem that light and light powder are not easy to mix; Because the structure of the double-cone mixer determines that the ribbon blade added by it is very small, when the light powder floats above in the mixing process, the blade can not wrap the upper light powder to participate in mixing.
The dual-power hybrid device has a loading rate of up to 85%, which can reduce the space for light powder to float, while increasing the internal accumulation pressure of the powder. The rotation of the barrel ensures that the material has no dead Angle. The main mixing method is to cut, stir, insert and wrap the material with the spiral blade. The traditional double-cone mixer, three-dimensional mixer and V-type mixer mainly rely on gravity diffusion mixing, the inside of the barrel must leave enough inverse space, the best loading rate is not higher than 50%, the suspension space of light powder is too large, is not conducive to the mixing of light and heavy powder; This is also one of the reasons why dual-power mixing equipment can better solve the difficult problem of uniform mixing of light and heavy powder than traditional mixing equipment.
