The paper is concerned with the results of an investigation carried out to explore the possibilities of using attrition cells as an alternative to the current vat system used in the S. Antioco salt works in SW Sardinia for the production of washed sea salt. Laboratory tests were conducted varying the operating parameters residence time in the attrition cells and in the centrifuge, solid/brine ratio; number of revolutions per minute of the mechanical stirrer. The results obtained justify the proposal for setting up a pilot plant for their verification and for determining the influencing parameters for industrial design and scale up
