Decanter centrifuge
Decanter centrifuges are used for separation and dehydration of suspensions with a high content of solid particles.
Under the influence of the high centrifugal force created in the drum, due to the difference in density, small fractions of the solid substance are separated from the suspension, and transported due to the screw rotating at a slightly higher speed than the drum.
At the outlet, the dry fractions of the cake are discharged through a special opening for the solid phase, and the purified liquid leaves the drum through special drain windows.
