The capacity of a large capacity centrifuge as a separation and filtration device is often used as a criterion for evaluating its merits. Compared to small capacity centrifuges, large capacity centrifuges have several advantages.
Due to their larger capacity, large capacity centrifuges have the great advantage of higher separation efficiency. Under the same conditions of centrifugal force and time, more materials can be centrifuged and more separation effect can be realized. With the popularity of large-capacity centrifuges, more and more enterprises are beginning to pay attention to its energy consumption and floor space. Due to its higher separation efficiency, it can significantly reduce energy consumption and floor space in the case of accomplishing the same task.
Due to their relatively simple construction, high-capacity centrifuges are more suitable for long-term and continuous use. Easier to repair and maintain than smaller centrifuges and other filtration equipment, high-capacity centrifuges maintain their high efficiency and stability over longer service intervals. In addition to their high efficiency and ease of maintenance, they also offer a higher level of safety. Because of their more stable construction and the stringent safety and stability conditions that need to be met during centrifugation, large capacity centrifuges are better suited for operation in high-risk and complex environments.
Because of their larger capacity, they can undoubtedly handle larger volumes. Whether in areas such as pharmaceutical manufacturing or environmental protection, they can provide more effective separation and filtration services to a wider range of customers. The capacity and functionality enable it to be used in a wide range of different fields. In addition to the fields of pharmaceutical manufacturing and environmental protection, it can also be used in many other fields such as food processing, petrochemicals, electronics manufacturing, etc., providing effective separation and filtration technology for more companies. Large capacity centrifuges are commonly used industrial machines for separating solid particles or aerosols from liquids, as well as separating liquids of different densities. By applying centrifugal force in a rotating centrifugal cylinder, solids or heavy materials in liquids are separated, thus realizing the function of separation and filtration.
The principle of the large capacity centrifuge is simple yet complex. It is based on two important physical principles: centrifugal force and density gradient. Centrifugal force is a virtual force that is generated in the direction of the center of rotation. When an object is rotating, the centrifugal force is generated perpendicular to the axis of rotation. The components of a mixture are separated by the enormous centrifugal force.
Density gradients use centrifugal action to separate and extract different substances by layering them according to their density. According to the principle of buoyancy, the depth of immersion of an object is related to the density of the object. Lighter objects are subjected to lower buoyancy on water, while heavier objects sink to the bottom of the liquid. In a centrifuge, the material in the mixture is filled with material of gradual density so that the material in the mixture forms at different positions with a density gradient. At this point, the denser material (e.g. solid particles) sinks to the bottom of the concentration valley while the less dense material (e.g. liquid) assumes a laminar structure.
Therefore, by means of this principle, large-volume centrifuges reduce the separation time of mixtures to a few minutes or even seconds compared to conventional filters and sieves and enable purer separates to be obtained. Large capacity centrifuges have a wide range of applications and prospects in realizing efficient production. Every time I hear a large capacity centrifuge make a loud noise, I always think of its separation principle and its essence, which feels like a magic spell.
