Graphite powder is soft, dark gray; it has a greasy feel and can stain paper. The hardness is 1～2, and the hardness can increase to 3～5 with the increase of impurities in the vertical direction. The specific gravity is from 1.9 to 2.3. The chemical properties of graphite powder are relatively stable at room temperature, and are insoluble in water, dilute acids, dilute alkalis and organic solvents; the material has high temperature resistance and conductivity, and can be used as refractory materials, conductive materials, and wear-resistant lubricating materials. Therefore, the quality requirements for graphite powder are very high. The vibro sifter equipment can classify and remove the graphite powder very well, and screen out the particle size specifications that meet the customer's requirements. So which vibro sifter should be used for graphite powder? Dahan Vibration Machinery recommends that you use ultrasonic vibro sifter.
Ultrasonic vibro sifter can effectively screen larger than 500 meshes. Because of the installation of ultrasonic transducer system, ultrasonic vibro sifter does not need to add other screen cleaning devices. It has self-cleaning function and the mesh is not blocked, which can further improve the screening efficiency. The transmission rate of the vibro sifter installed with ultrasonic is increased by 5-20 times. In addition, the ultrasonic vibro sifter can also be used in single layer and multi-layer, a set of intelligent ultrasonic generator can use three transducers at the same time, and can ensure that the physical properties of the processed materials remain unchanged. It can also improve the screening output and accuracy.
1. High sieving accuracy: Ultrasonic vibro sifter can be finely divided to 50 mesh or 625 mesh, which can screen graphite powder with high precision.
2. Good screening effect: Thanks to the addition of an ultrasonic transducer, the screening accuracy can be increased by 1-70% and the output can be increased by 0.5-10 times without changing the characteristics of the material.
3. No blocking of the screen: with self-cleaning function, no need to add other screen cleaning devices, the mesh is not blocked, and effectively solves the problem of blocking the network during the screening process of the negative electrode material.
