Controlling the hydration and carbonation in lime-based materials ...
Fig. 3a and 3b clearly show that NaCl did not affect the particle size of the lime, but that sugar made the lime powder finer. The latter resulted in the formation of many small particles in the range of 500 nm–5 µm ( Fig. 3 a), which decisively contributed to the markedly smaller average particle size of the hydrated lime sugar samples ([HL] Su3.5

Experimental Study on the Cracking and Mechanical Properties of Lime
Lime with the particle size of 150–200 mesh acts as the “fine aggregate” in silty clay and plays a bonding role in the slaking process of lime soil, which makes some lime and soil particles form a cohesive body, increasing the particles with particle sizes greater than 2 mm and reducing the particles with particle sizes less than 0.074 mm.

The kinetics of lime slaking - ScienceDirect
Abstract. Although the slaking of lime is a reaction of great antiquity, there have been few fundamental studies of its kinetics and mechanism. In this paper, the kinetics of the reaction are reported for lime samples in two different arrangements: rotating discs and powders. In the former case, the rate was measured by solution analysis; in ...

The kinetics of lime slaking - ScienceDirect
In this paper, the kinetics of the reaction are reported for lime samples in two different arrangements: rotating discs and powders. In the former case, the rate was measured by solution analysis; in the latter, by calorimetry. The rate of slaking of a rotating lime disc was approximately constant with time but depended on the disc rotation speed.

Influence of the traditional slaking process on the lime putty ...
The results obtained in particle size characterization for samples slaked in the laboratory (Fig. 12) show similar distributions for water-to-lime ratios 1/3, 1/4 and 1/5, but a distribution with bigger particle sizes can be observed for a sample slaked with less amount of water (1/2).

A New Approach for Particle Size Reduction in Lime Slaking
For example, for SO2 capture with ground limestone in wet FGD, much of the coarser particles never react with gasses because of a short contact period and these particles are basically wasted. For limestone to react with SO2 gas, there should be some dissolution of limestone so that it can ionize. Fine pulverization generally improves the rate of
