The evolution of white ash powder from limestone to wall materials

Lime powder commonly known as white ash, in the construction site sometimes found, which calcium oxide, magnesium oxide content on the strength of the two ash crushed stone grass-roots level of the impact is very large, but also the effective content of what we most often say, the control of white ash by raymond mill grinding fineness is also an important basis for safeguarding the performance of its use, then how is the processing of white ash? What are the specific links to go through?

Mining to the rock, its important into the powder is calcium carbonate, first of all through the calcination of the chemical reaction that occurs to produce calcium oxide and carbon dioxide, at this time to get the ore that is limestone, also known as quicklime, which is often referred to as white ash there is a certain difference between quicklime and the hydration of the exothermic reaction of the water in order to become a slaked lime is also used in the construction of the commonly used putty powder, the process does not need to be ground through the mill grinding, the lime can be automatically eliminated when it meets water. Lime can be automatically dissolved into a paste for its use in the presence of water, which is the evolution of limestone into the process of white ash powder, if the fineness of the requirements are particularly high, you also need to air-dry by the milling equipment to regrind.

Which quicklime (calcium oxide) for the reaction to produce slaked lime before its use is also relatively wide, can be used as a desiccant, bleaching powder, cement quick solvent, etc., especially in the power plant desulphurisation, sewage treatment to facilitate the effect is remarkable, of course, the processing of quicklime need Raymond mill to complete with different roles according to different finished product finenesses are very different, you need to choose a different milling equipment to Raymond mill, high pressure mill, Europe version of the mill in the Processing process is the most common.

Whether it is lime powder, white ash powder or putty powder in the production of grinding equipment has an inevitable link, at present, gypsum powder, talcum powder in the building materials are also more widely used, especially talcum powder fine, glossy and more components for the ideal choice of new wall materials.
