With the continuous development of industrial technology and the increasingly mature manufacturing technology of petroleum coke dryers, different types of equipment use different manufacturing processes, and the methods of drying materials are also different. So, which drying method is better for petroleum coke dryer drying materials?

  The methods of drying materials in petroleum coke dryer mainly include co-current drying and counter-current drying to process materials.

  Downstream drying: Downstream drying means that high-humidity petroleum coke and high-temperature hot air enter the cylinder from the same end of the equipment. At this time, the material is in contact with the hot air in the same direction, and with the continuous rotation of the cylinder, gradually The process of moving to the discharge end, and in the process of continuous heat transfer, the moisture in the wet material is evaporated.

  Counter-flow drying: that is, the wet material and the high-humidity hot air run in the opposite direction, and the two enter the cylinder from the two ends of the cylinder of the petroleum coke dryer respectively. And with the continuous operation of the drying cylinder, in the process of moving the wet material from the feed end to the discharge end, it gradually contacts with the oncoming high-temperature hot air, and realizes the process of heat exchange.

  Both methods have their own advantages. Which drying method is better for the specific petroleum coke dryer should be determined according to the characteristics of the material and the actual production needs of customers.
