Vertical centrifuge is a kind of efficient solid-liquid separation equipment, which is composed of feeding device, separation system, filtration silo, discharging silo, transmission system, washing device and electronic control device.
The whole system of the vertical centrifuge cleverly uses the dual action of centrifugal force and gravity to realize the continuous work of the equipment and achieve a high working efficiency.The slurry enters the centrifuge from the feed port, and is subjected to the centrifugal force in the separation system. The solids are intercepted through the filter screen, and the liquid enters the filter silo through the screen and is discharged from the mother liquid port.The solid moves downward under the action of gravity and centrifugal force, and enters the lower section through the discharge bin.In the process of movement, the washing system is pumped into the washing liquid to wash the solid.All power is driven by an electric motor.During the separation process, the residence time of solids in the separation system can be controlled by adjusting the feeding speed and the relative positions of each part of the separation system, so as to meet the specified requirement of solid water content.
Centrifugal principle
When a suspension containing fine particles is standing still, the gravity field causes the suspended particles to sink gradually.The heavier the particle, the faster it sinks, whereas particles that are less dense than liquid rise.The speed of the particle moving in the gravitational field is related to the size, shape and density of the particle, as well as the strength of the gravitational field and the viscosity of the liquid.Particles the size of red blood cells, a few microns in diameter, can be observed settling under normal gravity.
In addition, there is diffusion phenomenon when the material settles in the medium.Proliferation is unconditional and absolute.Diffusion is inversely proportional to the mass of the material, and the smaller the particle, the more serious the diffusion.The settlement is relative, conditional, to be subjected to external forces to move.Settlement is proportional to the weight of the object, and the larger the particle is, the faster it settles.For particles smaller than a few microns, such as viruses or proteins, which form colloidal or semi-colloidal states in solution, it is impossible to observe the sedimentation process using gravity alone.The smaller the particle is, the slower it settles, and the more serious the diffusion is.Therefore, it is necessary to use a centrifuge to generate strong centrifugal force to force these particles to overcome the diffusion and sedimentation motion.
Centrifugation is to use the powerful centrifugal force generated by the high-speed rotation of the centrifuge rotor to accelerate the settling speed of the particles in the liquid and separate the substances with different settling coefficients and buoyancy densities in the samples

Note: TWZ series horizontal vibrating centrifuge external water related to material properties, particle size composition, processing, but mainly depends on the material content of coal slime. Into the material - 0.5 mm size content < 10%, TWZ series horizontal vibrating centrifuge external water for 5 ~ 9%.
