Have you ever had information about the applications of sintered dolomite? Did you know that sintered dolomite is the most important type of dolomite?
Definition of Sintered Dolomite
Sinter dolomite, also known as dead burnt dolomite, is created by heating raw dolomite to a temperature greater than 1650 °C, ideally greater than 1800 °C.
Magnesium ingots and refractory goods are both made from sintered dolomite.
Heat and CaCO3 + MgCO3 = CaO + MgO
A single stage burning procedure in a shaft kiln or rotary kiln is the most typical method for producing sintered dolomite.
The kiln is charged with raw dolomite, which decomposes in two processes as it moves through the kiln. At temperatures around 550 degrees Celsius, the MgCO3 component of dolomite begins to emit CO2, while at temperatures around 810 degrees Celsius, the CaCO3 component of dolomite begins to disintegrate.
Applications of Sintered Dolomite
An iron producer uses dolomite in the calcined phase during the sintering process. It aids in carbon dioxide removal.
Before being added to the sinter mix, it is first reduced in size using hammer crushers to 3mm.
Contacting a dolomite producer for its calcined phase has some advantages, such as:
It enhances the sinter mix's binder properties.
2-It increases the productivity and efficiency of the sintering machine.
- It makes the sinter stronger.
4-It also lessens the release of gas stream, which has various benefits.
Specifications Of Sintered Dolomite
The manufacturing of sintered dolomite and limestone cement with respective apparent densities of 3.28-3.31 and 2.96 g/cm3 at 1400–1500° C is made possible by the calcination of pure, challenging-to-sinter varieties of stones, which require a calcination firing and subsequent slaking of the material.
When calcium fluoride is added, the rate of lime crystallization increases and the temperature of first mass selecting sintering during firing of the dolomite and carbonate is noticeably lowered.
As a result, the extensive sintering of the material takes place at lower temperatures.
The calcium fluoride-added dolomite clinker produced by sintering has a significantly greater moisture resistance.
The Price Of Sintered Dolomite In Bulk
Dolomite's wholesale pricing is established based on a few crucial factors.
In addition to determining the prices for individuals who supply services in the locations where these sorts of stones are produced and harvested, these fees ought to take into account the energy used in the factories. be their output and adequately pay these expenses so that the industrial facility may keep operating.
Industrialists have recently shown a great deal of interest in the supplier of sintered dolomite.
Interesting Facts About Sintered Dolomite
The sinterability of the raw dolomite, which is influenced by the unique textural properties including chemical composition, purity, homogeneity, origin, genesis, porosity, and crystal structure, is a key factor in how well the sintering process performs.
When using high-purity raw dolomite, an acceptable product quality is frequently only possible when the dolomite is combined with solid fuels, with the fuel impurities serving as "sintering aids."
