دردشة مباشرةThe raw materials needed to produce cement (calcium carbonate, silica, alumina and iron ore) are generally extracted from limestone rock, chalk, clayey schist or clay. Suitable reserves can be found in most countries. These raw materials are extracted from the quarry by blasting. They are then crushed and transported to the plant where they are stored and homogenized.
دردشة مباشرةTherefore the aerated powder tends to behave like a liquid and by aerating all quadrants in turn for a total period of about one hour, a uniform mixture is obtained. In some cement manufacturing plants continuous blending is used. The blended meal is further passed into sieve and then fed into a rotating disc called granulator. A quantity of ...
The heated air from the cooler is returned to the kiln, saving fuel and energy in the process. Step 5: The cooled clinker is mixed with gypsum and then sent to a grinding mill where it is ground into a fine powder. Cement is so fine that one kilogram of powder contains about 300 billion grains.
