hydrated lime

Mechanically activated highly dispersed hydrate lime

The technology for producing highly active hydrated lime using vibromechanical treatment of lime suspensions has been developed. The processes occurring during the high-frequency mechanical impact on calcium hydroxide microcrystals are investigated. The optimal parameters of vibration treatment of lime slurries were determined. The distribution of lime particles by particle size distribution was determined by laser granulometry, and the change in the morphology of Ca(OH)2 microcrystals after mechanical impact was studied.

CRITERIA FOR RESEARCH OF THE PROCESS OF DISPERSION OF THE SYSTEM OF HYDRATE LIME-WATER

The process of dispersion of slaked lime in a vibrating activator of the bunker type is investigated. The nature of the change in the viscosity of lime dough during machining by vibration and rotary viscometer has been studied. It is established that the process of vibroactivation of hydrated lime successively goes through the stages of proportional growth of dynamic viscosity, slowing down its growth and cessation of dispersion. The efficiency of using the vibration method for determining the viscosity of the hydrated lime - water system is shown.
