Caustic lye preparation involves dissolving solid sodium hydroxide flakes or pearls into water while managing one of the most exothermic dilution reactions in chemical processing. Traditional tank dumping often leads to local overheating, crust formation, operator exposure, and inconsistent concentration.
The Wahal Liquid Powder Mixer (LPM) enables controlled, dust-free powder induction directly into a high-energy liquid zone. The CNC machined rotor–stator generates intense local turbulence, ensuring instant wetting of caustic flakes and uniform heat distribution across the batch.
Typical process parameters include solids addition rates of 2–6 TPH, liquid recirculation of 20–80 m³/hr, and final concentrations up to 50%. Automated powder dosing ensures that induction rate is matched with cooling capacity, preventing runaway temperature rise.
