The research results concerning attrition of sodium chloride crystals in two types of jet pump crystallizers are presented. It was demonstrated that in the crystallizer with a jet pump crystals undergo considerable smaller attrition compared to the one equipped with agitator and draft tube (circulation profile). The influence of the initial mean crystal size, crystal volumetric concentration in the suspension and the residence time of the suspension in the crystallizer on the degree of solid phase destruction was determined and quantified in the form of empirical equations. The DTM MSCPR construction demonstrates the least destruction capabilities.
