slakers are generally used where the capacity required is too large for other types of slakersWestpros Ball MillType lime slaking design provides excellent slaking of lime while discharging no grit Our system ensures the finest particle size by recycling coarse particles for further grinding Advantages Safe simple and trouble free operation No practical upper limit for capacity Recycles coarse particles to the mill for further grindingThe water to lime ratio in the mill is adjusted automatically to maintain a constant slaking temperature based on a temperature probe directly in the mill Vertical ball mill slakers typically operate between 75 oC and 85 oC and like conventional detention slakers they can with good water temperature control and a stable lime supply be runStandard Horizontal Ball Mills are sometimes used for lime slaking Considering that Ball Mills are designed for grinding and the slaking process is simply a chemical process it is obvious that the use of a Ball Mill for slaking is not the best choice of equipment in most cases However there are a few cases where the use of a Ball Mill slaker is advantageous These include 1 Where the slaking water isStirred mills are used for wet grinding Ideal for grinding finer products stirred mills are known for operational efficiency and smaller required floor space Metso offers both gravityinduced and fluidized technologies in Vertimill and Stirred Media Detritors SMD allowing for the optimum equipment solution forC Ball Mill Slakers A slaker must mix the correct amount of quick lime CaO and water hydrate the quicklime a nd separate the impurities and grit from resultant calcium hydroxide slurry A SLURRY SLAKERS A slurry slaker generally uses an initial lime to water ratio of 1 to 33 to 1 to 5mounted ball mills suitable for quicklime slaking and regrind applications The mills range from 600mm diameter for laboratory batch testing applications through to the largest mill currently available of 23m diameter with an effective grinding length of 46m SEW Eurodrive geared reducers are used exclusively on Lime Systems mills and all units have fully automated grease lubricationThe Ball Mill slakers can be effectively used for slaking dolomatic pebble lime since pebbles will be ground to a fine particle size The mill temperature for slaking dolomatic pebble lime should be about 200F With this high temperature special mill lining must be used The normal mill rubber line will deteriorate at this temperatureBallRod Mills based on 4 liners and capacity varying as 26 power of mill diameter on the 5 size give 20 per cent increased capacity on the 4 size 25 per cent and on the 3 size 28 per cent This fact should be carefully kept in mind when determining the capacity of a Steel Head BallRod Mill as this unit can carry a greaterThe resultant hydrated lime exits the grinding chamber into a separation tank There heavier larger partials settle while finer suspended particles discharge Larger particles are pumped from the separation tank bottom back into the mill to pass through the bed of grinding media Special Features of Chemco Ball Mill SlakersBALL MILLTYPE Westpros Ball MillType lime slaking design provides excellent slaking of lime while discharging no grit Our system ensures the finest particle size by recycling coarse particles for further grinding ADVANTAGES Safe simple and trouble free operation No practical upper limit for capacity Recycles coarse particles to the mill forLimestone can be directly processed into aggregated rock and burnt into unslaked lime which becomes slaked lime after its moisture water absorption The main content of slaked lime is CaOH2 Slaked lime can be blended into lime slurry lime putty lime mortar etc Which can be used as coating material brick tile adhesiveC BALL MILL SLAKERS Ball mill slakers are an adaptation of ball mills which originally were designed for wet and dry grinding to lime slaking Two types of ball mills are used for slaking horizontal and vertical Ball mill slakers are generally used where the capacity required is too large for other types of slakers lime slaking ball millLime slakers are an important tool for converting calcium oxide CaO which is also known as quicklime or pebble lime into a calcium hydroxide CaOH2 slurry Quicklime is a popular alternative to purchasing hydrated lime because it is more affordable and requires around 75 percent less of the chemical by weight as hydrated lime meaningIn fact in the same application a Vertimill has 50 less footprint than a ball mill Lower operating cost Vertimill is an energy efficient grinding machine They tend to grind more efficiently than for example ball mills with feeds as coarse as 6 mm to products finer than 20 microns This provides up to a 40 higher energy efficiencyMar 08 2013 calculation of ball mill grinding efficiency dear experts please tell me how to calculate the grinding efficiency of a closed ckt open ckt ball mill in literatures it is written that the grinding efficiency of ball mill is very less less than 10 please expalin in aIn this article alternative forms of optimizing the milling efficiency of a laboratory scale ball mill by varying the grinding media size distribution and the feed material particle size distribution were investigated Silica ore was used as the test material The experimental parameters that were kept constant in this investigation was theSepro Lime Slaking Ball Mill by SeproMineralSystems 1036 views Design of chemical feed systems lime slaking ball mills and

globalIn Pfeiffer lime hydrators quicklime lumps are converted into lime hydrate by adding water In downstream Pfeiffer separators highpurity lime hydrate is separated from the grits These are ground to target fineness in ball mills which operate in closed circuit with separators thus producing building limeSchellingers calculated ball mill efficiency in dry or wet ball mill grinding ranges between 10 and 19 with the higher figure occurring at the optimal mill loading In terms of the Brace and Walsh surface free energy of quartz his results give a ball mill efficiency that is less than 05In the lime hydrator quicklime fines or quicklime lumps turn into lime hydrate CaOH2 after the addition of water at a temperature of approx 100C The requested residual moisture of the hydrate is regulated by a temperaturecontrolled water supply and a variable material retention timeLime slaking is the process of converting quicklime to hydrated lime CaO H20 CaOH2 by mixing with water Lime slaking is an exothermic process which generates heat and creates steam Slaked or hydrated lime is often used in mining and process industries forThere is a similar process in which an excess amount of water is used to hydrate the lime This process is referred to as lime slaking and the product discharged from a lime slaker takes the form of a slurry Information specific to Metso lime slakers is
