NPO Passat manufactured and supplied leaching apparatuses for processing plant of the 3rd Production Unit Belaruskali, JSC. They were designed for the reconstruction of the technological sections of the processing plant.
Apparatuses with a mixing device were designed to improve the quality of the concentrate after a cleaning operation by dissolving free NaCl from the surface of the crystals with mechanical mixing. The volume of devices is 12.5 m3. Apparatuses were manufactured from stainless steel. The mixing mechanism was selected to ensure effective contact of the leaching solution with the pulp and to eliminate the effect of mechanical rubbing of the fine fractions of the solid, not to allow the pulp to separate and to mix over the entire volume of the apparatus.
