In this particular sector, very often the substances handled are particularly aggressive and this enforces the use of corrosion resistant materials on the parts of the machine in contact with the product to be treated. Consequently, the solid and liquid discharges, the auger and the drum are manufactured in Duplex or Superduplex steel or other materials resistant to aggressive chemical substances.
Some applications of the centrifuge in this sector concern the recrystallization process of the salts, in order to obtain a high level of saline purity, or washing solid products in order to extract the liquids loaded with useful substances.
