What are the differences between centrifuge and vibrating screen?

2020/9/30 9:11:14

Both the vibrating screen and the centrifuge are separated by vibration, but the working principle of the vibrating screen and the centrifuge is still somewhat different, and the scope of use is also different.
Centrifuge is a machine that uses centrifugal force to separate liquid and solid particles or each component in a mixture of liquid and liquid. Centrifuge Centrifuge is a machine that uses centrifugal force to separate the components in the mixture of liquid and solid particles or liquid and liquid. Centrifuge is mainly used to separate the solid particles in the suspension from the liquid; or to separate the two incompatible liquids in the emulsion with different densities (for example, separating cream from milk); it can also be used to remove Liquids in wet solids, such as drying wet clothes with a washing machine; special ultra-velocity tube separators can also separate gas mixtures of different densities; using different density or particle size solid particles in the liquid to settle at different speeds, and some sedimentation The centrifuge can also classify solid particles according to density or particle size. At present, the common centrifuges on the market include filter centrifuges and decanter centrifuges. They are widely used in the chemical, petroleum, food, pharmaceutical, mineral processing, coal, water treatment and shipbuilding sectors, and in the chemical, food, medical, etc. It has been widely used in the preliminary sample analysis in the field.

The vibrating screen works by using the multi-rotating vibration generated by the vibrator. The upper rotating weight of the vibrator causes the screen surface to produce plane whirling vibration, while the lower rotating weight causes the screen surface to produce cone-shaped rotary vibration. The combined effect of the vibrator causes the screen surface to produce multi-rotating vibration. Its vibration trajectory is a complicated spatial curve. The curve is projected as a circle on the horizontal plane, and projected as an ellipse on the vertical plane. The amplitude can be changed by adjusting the excitation force of the upper and lower rotating weights. Adjusting the spatial phase angle of the upper and lower weights can change the curve shape of the screen surface movement trajectory and change the movement trajectory of the material on the screen surface. At present, the common vibrating screens on the market are mainly mine vibrating screens, light fine vibrating screens and experimental vibrating screens. They generally have high efficiency, light weight, complete and diverse series, multiple levels, and can screen dry materials. Features such as meeting demand. Therefore, vibrating screens are widely used in mining, coal, smelting, building materials, refractory materials, light industry, chemical industry, medicine, food and other industries, and coal preparation, mineral processing, building materials, power and chemical industries for product classification.

From the above analysis, it is not difficult to see that the equipment used in the centrifuge and the vibrating screen is not nearly the same for different materials and products with different specific gravity.
