Difference between the working principle of vibrating screen and centrifuge

Both the vibrating screen and the centrifuge are equipment for classifying materials, but the working principle and the scope of application are very different.

The vibrating screen works by the compound-rotation vibration generated by the vibrator excitation. The upper rotating weight of the vibrator causes the screen surface to generate plane whirling vibration. In contrast, the lower rotating weight causes the screen surface to generate conical surface rotation vibration. Its vibration trajectory is a complex space curve. The curve is projected as a circle on the horizontal plane and as an ellipse on the vertical plane. Adjusting the exciting force of the upper and lower rotating weights can change the amplitude. And adjusting the spatial phase angle of the upper and lower weights can change the curve shape of the screen surface movement track and change the movement track of the material on the screen surface. For screening and grading of various solid and liquid materials and plants.

A centrifuge is a machine that uses centrifugal force to separate and extract each group of liquid and solid particles or a mixture of liquid and liquid.

The centrifuge is mainly used to separate the solid particles and liquids in the suspension and the two kinds of liquids in the emulsion with different densities and incompatible with each other, so as to extract and separate various materials.
Therefore, it can be seen that the different working principles of the vibrating screen and the centrifuge, the different materials, the products with different specific gravity and the scope of application of different requirements are also very different.
