What Is Slaking Of Lime? | Process Of Slaking |2020|

When the quick lime or lime is reacted or comes in contact with water it readily absorbs this process is known as the Slaking of lime or Hydration of lime Quick lime – When the pure limestone is calcine in a kiln then we get quicklime Calcination – The process of heating limestone at 900ºC or above in a kiln is known as calcination

AN OVERVIEW OF LIME SLAKING AGT Group

The most important single factor that affects the process efficiency of a slaking system is the specific surface area of the particles of calcium hydroxide The larger the specific surface area of the hydrate, the more surface is available for reaction, therefore, the more efficient the reaction and less consumption of lime The specific surface of calcium hydroxide varies a great deal based upon the variables that are described below The typical specific surface of calcium hydroxide ranges between 8,000 to 58,000 Cm2/gr Empirical data shows that the relationship between the particle size of hydrate and specific surface, even though related, is not linear Figure 8 shows 10 different limes

AN OVERVIEW OF LIME SLAKING AND FACTORS THAT

Waterchemistry is a major factor in the slaking process Presence of certain chemicals in the slaking water will accelerate or hinder the slaking process Water with high dissolved solids generally causes excessive foaming, which results in operationalms Waters problecontaining over 500Mg/l of sulfates or sulfites are unsuitable for slaking This is true for paste and slurry type lime slakers Ball

lime slaking process casa21be

LIME SLAKING PROCESS AND ITS IMPACT ON

Two slaking tests were performed using the same lime and water On test “A”, the slaking water was heated to 249°C (768°F) and temperature rise was 48°C (1184°F) which indicates a highly reactive lime The second test “B” was done with same lime and water with initial temperature of 352°C (953°F) and temperature rise was 529°C (1272°F) The second test showed an increase in temperature of 42°C (396°F) when compared to test

Influence of the traditional slaking process on the lime

Lime quality has been traditionally related with factors such as the origin and calcination method of the limestone, the nature of the slaking process or the age of the lime putties The experience and skills of the professionals involved in the lime cycle, from slaking to application, are also key factors to success in the use of these materials

The kinetics of lime slaking ScienceDirect

The rate of slaking of a rotating lime disc was approximately constant with time but depended on the disc rotation speed In the presence of Ca 2+ or OH − ions, the slaking rate was reduced These results were accounted for by assuming that the slow step in the early stages of the slaking reaction was the diffusion of calcium hydroxide away
