OPTIMISATION OF SALT SEPARATION ON PUSHER CENTRIFUGES
Every salt production plant needs a centrifuge to separate the salt produced in the evaporator/crystalliser by centrifugal force. In this way, the salt can be recovered in a ready to use form and with low residual humidity. This is what the pusher centrifuges of Ferrum and previously Escher Wyss have been doing worldwide for decades. Thanks to further advances, further improvements have been introduced that can have positive effects within the entire plant. When the solids cake is washed in the centrifuge, clean salt can be obtained or elutriation can be reduced. As centrifuges are always subject to a certain amount of contamination (crystallisation on the outside, slots blocking, solids deposits in the discharge area), they need to be cleaned periodically. Appropriate changes to apparatus and equipment allow the time needed for this step to be optimised and work for the operator simplified. Screen clogging occurs due to the product after several hours through crystallisation, which results in increased residual humidity. This process can be slowed down substantially by using modified screens.
