The calcium silicate compositions created in the rotary kiln emerge in a "clinker" form, that is, in small granules with diameters of approximately 1 to 4 mm. The clinker is then ground to a powder with a mean particle size of approximately 12 μm. To produce concrete, this material is mixed with aggregates, sand and water.
Rotary cooler is one kind of cement cooler applied for cement manufacturing plants.As an essential part of the cement kiln system, a rotary cooler is used to cool the clinker discharged from the cement rotary kiln.The rotary cooler also helps air to absorb the large amounts of heat carried by clinker, heating the combustion air up to the high …
