Stainless Steel Milk Cream Electric Centrifugal Separator Machine HGDR230
Disc separator is a vertical centrifuge. Drum installed on the upper end of vertical shaft, drive by a motor through a transmission device and high-speed rotation. There is a set of nested with each other together of the disc parts-disc in the drum. The small gap is left between disc and disc. Suspension (or emulsion) enters into drum through the feeding tube of the centre of drum. When the suspension (or emulsion) is going through the gap between the discs, solid particles (or droplets) sink down the disc and form sediment (or the liquid layer) in the effect of the centrifuge. Sediment slides along the surface of the disc, is out of the disc and accumulates in the part of the largest diameter of the drum. Liquid after separation discharge out of the drum through the discharge port. The role of the disc is to reduce the settlement distance of the solid particles (or droplets), to expand the settlement area of the drum. Separator's capacity is greatly improved with installing discs. The solid accumulating in the drum is eliminated manually after the separator stop, or discharged out of drum through slag machine when the separator does not stop.

Work principle :
Use the differences in density between the different substances, the centrifugal force separation and extraction of physical separation techniques. In the gravitational field, known as gravity separation, in centrifugal field called the centrifugal separation.
Gravity separation
Big density solid particles of the mixture slowly sinking under the gravitational attraction, the mixture become clear and the density small of liquid is up. Gravity separation takes a long time and occupies a lot of area. It's different to separate ,especially when the density is close and viscosity
Centrifugal separation
Mixture with different density become a circular ring under the force of centrifugal in a high -sped rotating drum, the particle with max density move outward to the wall of the drum while the small density of liquid in the innermost layer. Centrifugal separation just take only a short time that can get the effect of gravity separation because the centrifugal force formed by the high -speed rotation of drum is much bigger than gravity
Separation Space
There are a ground of discs within the drum of the disc separator which can divided the drum space into many thin-layer , it greatly shorten the settling distance and improve the separating effect..
Movement route of the particles C in the separation space Reference Figure 1-3
If any particles between A and B can reach the internal surface of the disc can be separated.
Separation
Usually, the separator is divided into two types. One is used for solids and two liquid phases from each other in one single continuous process, it is so called purifier. The other is used for solids and one liquid phase from each other, it is so called clarifier.
