AI Technical Summary
In the existing dry digestion process for producing highly active calcium hydroxide, the fixed process parameters cannot adapt to fluctuations in raw materials and operating conditions, resulting in unstable product specific surface area and poor mixing effect.
A vertical premixer is adopted, equipped with independently driven first and second stirring tools. Combining a shear rheology coupling model and a temperature-mass-speed cascaded adjustment strategy, the stirring speed and discharge opening are dynamically adjusted through a central control unit to ensure constant shear power density and avoid overheating or uneven mixing.
This method enables the efficient and stable preparation of high specific surface area calcium hydroxide under fluctuating load conditions, improving mixing efficiency and product activity uniformity, avoiding insufficient or excessive shearing due to load changes, and ensuring reaction temperature control.
