The centrifuges produced by horizontal screw centrifuges are machines that use centrifugal force to separate components in liquid solid particles liquid liquid mixtures.

The centrifuge is mainly used to separate the solid particles in the suspension the liquid, separate the two immiscible liquids with different densities in the emulsion (for example, cream is separated milk); it can also be used to remove the liquid in the wet solid, for example, use the washing machine to dry the wet clothes; the special overspeed tube separator can also separate the gas mixture with different densities; use different Some settling centrifuges can also classify solid particles according to their density particle size. Centrifuge is an instrument that uses high-speed operation to produce strong centrifugal force to accelerate the separation of different materials.

Centrifuges are widely used in medical, blood station, scientific research, nuclear medicine, agriculture animal husbandry, marine research center, laboratories of universities, chemical industry, petroleum, food, pharmaceutical, mineral processing, coal, water treatment ship use departments.

The main principle of the filter centrifuge is to accelerate the liquid phase in the solid-liquid mixture out of the drum by the centrifugal force generated by the high-speed running centrifugal drum (with appropriate filter materials), leave the solid phase in the drum to achieve the effect of separating the solid liquid, commonly known as the effect of dehydration. The main principle of the settling centrifuge is to accelerate the settling speed of different specific gravity components (solid liquid phase) in the mixed liquid through the strong centrifugal force generated by the high-speed rotation of the rotor, separate the materials with different settling coefficient buoyancy density the samples.

Centrifuges are widely used in mineral processing, coal, water treatment, shipping other sectors. The selection of centrifuge must be based on the size concentration of solid particles in suspension ( emulsion), the density difference between solid liquid ( both), liquid viscosity, the characteristics of filter residue ( sediment). the perspective of application, centrifuges are divided into laboratory centrifuges industrial centrifuges.
