Decanter Centrifuge Ore Dressing Equipment Horizontal Screw
Discharge
1. Basic introduction of decanter centrifuge
The decanter centrifuge is a new type of horizontal screw discharge
centrifuge. Its working principle is to use the solid-liquid
specific gravity difference, and rely on the centrifugal force
field to expand it thousands of times. The solid phase is settled
under the action of centrifugal force, thereby realizing The solid
and liquid are separated and discharged from the body under the
action of a special mechanism. The whole feeding and separation
process is completed continuously, closed and automatically.
The suspension added to the drum forms an annular liquid layer
under the action of centrifugal force, and the solid particles in
it settle on the drum wall to form a sediment. The clear liquid is
discharged through the overflow port of the drum or the suction
pipe, which is called the separated liquid. At the end of the
separation, the sediment is discharged manually or mechanically.
During the process of settling to the drum wall, the solid
particles also move axially with the liquid flow. When the feed
amount is too large, they flow to the overflow port with the
liquid, while the fine particles that have not settled on the drum
wall are discharged with the separation liquid. Rotate the drum to
make the separation liquid cloudy. For the difficult-to-separate
suspension with small solid-liquid phase density difference, small
solid particles or high liquid viscosity, a sedimentation
centrifuge with a high separation factor should be selected to
prolong the residence time of the suspension in the drum (for
example, reducing the feed amount or using a long drum, etc.), to
ensure that the separation liquid is clear. The decanter centrifuge
has a wide range of uses, especially for the separation of
suspensions in centrifugal filtration when the filtration
resistance is too large or the fine particles are lost too much
because the solid particles are easy to block the filter medium,
but the moisture content of the sediment is high. The decanter
centrifuge can be used for the separation of crystallization,
chemical sediment, coal powder and other suspensions, the
dehydration of various sewage sludge, and the slag removal and
clarification of animal and vegetable oils.
