2 Phase Decanter Centrifuges Description
The feed product is pumped into the decanter centrifuge through an inlet. Feed into a horizontal bowl and then rotate. The bowl consists of a cylindrical portion and a conical portion. The separation takes place in the cylindrical part of the bowl. Fast rotation produces centrifugal forces of up to 4000 x g. Under these forces, solid particles with a higher density are collected and compacted on the wall of the bowl. The scroll (also a screw conveyor or screw conveyor) rotates inside the bowl at slightly different speeds. This speed difference is called a differential speed. In this way, the scroll conveys the precipitated particles along the cylindrical portion of the bowl to the conical end of the bowl. At the smallest end of the conical portion of the filter bowl, dehydrated solids leave the filter bowl through the discharge port. The clarified liquid exits through the mating disc (internal centrifugal pump).

2 Phase Decanter Centrifuges Features
The machine can operate with a higher throughput capacity than
smaller machines.[5] This also reduces the number of units
required;
The device is simple to optimise and operate as it has few major
variables and reliable feedback information;
The decanter centrifuge has reduced labour costs compared to other
processes, as it requires low continuous maintenance and operator
attention;
Compared to some competitive process such as the belt filter
process, the decanter centrifuge has more process flexibility and
higher levels of performance.
