As we know, cement making production line is one of the biggest investment in the mining machinery, it not only need the cement griding mill machine, but also the flotation system. One of the important point to choose the configuration of the machines is depend on the kind of the cement. While the most common kind is the Portland cement. So today we will analyse the chemical component of the Portland cement, stone and aggregate production equipment in india which is to say the raw material made up of Portland cement.
Cement is made by heating limestone (calcium carbonate) with small quantities of other materials (such as clay) to 1450 掳C in a kiln, in a process known as calcination, whereby a molecule of carbon dioxide is liberated from the calcium carbonate to form calcium oxide, price of crusher plant 250-300 tons in the philippines or quicklime, which is then blended with the other materials that have been included in the mix. The resulting hard substance, called ‘clinker’, is then ground with a small amount of gypsum into a powder to make ‘Ordinary Portland Cement’, the most commonly used type of cement (often referred to as OPC).
Portland cement is a basic ingredient of concrete, mortar and most non-specialty grout. The most common use for Portland cement is in the production of concrete. Concrete is a composite material consisting of aggregate (gravel and sand), cement, and water. As a construction material, concrete can be cast in almost any shape desired, and once hardened, small stone crusher machine manufacturer in gujarat can become a structural (load bearing) element. Portland cement may be grey or white.If you have any more interest about the Portland cement, please feel free to contract us. We welcome all the friends from the home and abroad.
