Thermal coupling through the drum motor drive to do high-speed rotation around the main axis, the liquid feed pipe from the top center of flow to the bottom of the drum, the disc surface diversion hole trend to drum wall, the centrifugal force field, compared with liquid weight of solid phase formation of sediment sink to the drum wall, light liquid pumps to the heart by the light liquid exit discharge.
Heavy liquid within the cone along the disc tend to drum wall, then up to the heavy liquid flows through the heart pump discharges them from the heavy liquid, thus completing the heavy liquid and light liquid separation.
