The actual lime slaking process is performed either in a detention slaker or in a ball mill type slaker automated controlled by a PLC which monitors both lime and water feed rates slaking temperature and lime more lime slaking mill scrubber system onsmilcoza lime slaking ball mill A ball mill slaker either horizontal or a VERTIMILL is unique because instead of having to separate the grit from the lime slurry as it leaves the slaker the mill grinds the grit as the lime is slaked allowing it to carry on through the process as part of the milk of lime slurry

Besides the lime slaker itself Sodimate can also supply the complete “upstream” storage and feed system We engineer fully integrated dry storage and handling equipment for quick hydrated lime lime milk and lime slurries with uses ranging from water treatment to glass fabrication to road constructionPlant requiring large quantities of lime slurry could be cost effective if the quick lime is slaked on site The process consists of injecting quick lime in an agitated slaking tank maintaining high concentration The exothermic reaction by mixing quick lime with water creates heat and steam

Ball Mill The ball mill has two primary functions within the quicklime slaking system firstly the reduction of quicklime / hydrated lime into smaller particles critical to the correct reaction with process and secondly provide a rotating vessel to allow majority for the chemical reaction to occurHowever if the lime is injected into a solution we will also need a lime slaker The lime slaker is generally fit with a mixer and agitator all made of stainless steel in addition to a vacuum system lime scrubber that washes down and evacuates the heat and steam created from the reaction between the calcium oxide and water

PRINCIPLE OF OPERATION TYPICAL VERTICAL LIME SLAKING MILL A tower mill consists of a stationary vertical cylindrical body with a rotating screw or auger which extends from the top of the mill body almost to the bottom The auger rotates at a slow speed and circulates a charge of grinding balls inside the millHowever if the lime is injected into a solution we will also need a lime slaker The lime slaker is generally fit with a mixer and agitator all made of stainless steel in addition to a vacuum system lime scrubber that washes down and evacuates the heat and steam created from the reaction between the calcium oxide and water
