regardless of which kind of lime you need in order to improve the ph in your fields baker lime has the product you need. because both calcitic lime and dolomite lime can drastically change the mineral make-up of your fields you want to be sure that you are getting the product that is best suited for your needs.
a good correlation in decrepitation trend with change in particle size between the two methods was apparent for the dolomite and the maximum degree of decrepitation was found to be in the 180–250 μm (60–80 mesh) fraction by both methods.
as the properties of products are significantly affected by physicochemical specifications of limestone or dolomite the characterisation of those materials is important. this study was initiated to analyse the chemical decrepitation and degradation properties of dolomite and limestone samples to determine their suitability as flux.

calcining kilns need lime stone with decrepitation index. decrepitation index of limestone is a measure of its susceptibility to disintegration during calcination. low value of decrepitation decreases the porosity of the bed thus impeding the flow of the gases and reducing the kiln efficiency. rotary kilns also need limestone with good tumbling
in the south african limestone and dolomite industry there are currently 24 producers and 43 quarries. eleven limestone producers supply 80% of the south african market. dolomite and limestone are used commercially in unprocessed ground air-separated precipitated and calcined forms. cementitious products are derived from a blend of limestone
decrepitation of limestone and dolomite plotted as a function of particle size measured by the tg test. plots of the degree of decrepitation against particle size for limestone and dolomite are given in fig. 4. the limestone sample had a steady increase in decrepitation with increase in particle size reaching a maximum of 40% at 180 um (80 mesh).
limestone and dolomite flux and their use in iron and steel plant limestone is a naturally occurring mineral. the term limestone is applied to any calcareous sedimentary rock consisting essentially of carbonates.
aml's high calcium limestone and dolomite have demonstrated excellent decrepitation properties and calcination behavior superior to many other sources for use in vertical shaft kilns. the sulfur content is exceptionally low in both chemical grades. chemical grade high calcium limestone:
