Cooling Machine Is the Essential Heat Exchange Means

From the thermal and process point, there are four aspects can be usedto evaluate the Black powder magnetic separators. First, the cooling machine shouldrecovery much heat. Second, the time for cooling the clinker should beshort and the speed should be high, especially when the temperature isbetween 1250?and 525? Third, the temperature of the clinker cooledshould be low. Forth, the air consumption for unit clinker should belittle. Fifth, the cooling machine should have the advantages of simplestructure, convenient operation, easy maintenance and high operationrate. With the development of the cement industry, there are a lot of types ofthe Hydrated Lime Manufacturing Process. At present, the cooling machine can be dividedinto the following main types. The first is the single-tube cooling machine. All the cooling air entersthe kiln. The thermal efficiency is relatively high and the structureis simple. The exhaust gas processing apparatus is not necessary.However, the cooling speed for the clinker is low and the temperaturefor the clinker discharging from the machine is high. In addition, thesecondary air into the machine is not even. The second is the multi-drum cooling machine. This kind of Lead ore crushing machine is composed of several cylinders on the shell of the kiln. Inthis way, the specialized power equipment and the dust collectionequipment are not necessary. However, the load of the cylinder of thekiln may increase. At the same time, the cooling effect of the clinkeris not very good. The third is the floor standing cooling machine. For this kind ofcooling machine, all the cooling air enters the kiln and the thermalefficiency is high. In the actual production, each device is not isolated. The operationbetween the Construction Waste Recycling Plant and the kiln is restricted and influenced.Therefore, in the actual operation process, the users must carefullyanalyze the operation parameters of the cooling machine according to thespecific circumstances.
