Rotary dryer is drying equipment, and it can be widely used in many industrial field. As we all know, rotary dryer machine has many advantages, but we also still to solve some issue that they appear in the rotary dryer work process. And so far, the consumption of rotary dryer is a big problem for user, they seek many methods to solve it. Here we share three ways to reduce the consumption of rotary drum dryer.The three methods as following:1. The internal device of dryer: In recent years, the application of computer three dimensional systems in the mine design has promoted. The analysis and adjustment of material test increased to ensure the ingredients balance of raw material before into the machine. Grinding the raw materials with all features has declined gradually after grinding. As the rotating rate increased, the storage function is declining. Thus it is helpful for reducing the consumption of dryer.2. The rotating speed of dryer: Improving the speed of rotary drum dryer could increase the contact area between material and hot air to improve the efficiency. Therefore, the research department and some factories have increased the rotating speed to 8-10r/min of dryer in recent years. Thus the rotary dryer could use the recycling of drying medium, the internal device of dryer and the rotating speed of dryer to reduce the consumption of dryer.3. The recycling of drying medium: The heated oxygen went into the drying chamber and mixed with feeding materials. The feeding materials dispersed in the drying chamber. Moisture evaporated quickly and powder drying product was collected in a short time. The steam with drying medium discharged from the drying chamber to filter and the powder particles was separated immediately. Then the clean media was sent to the cooling machine and drying medium can be recycled. By doing so, it is one of the effective ways to reduce the consumption of dryer.ore tube drier: http://www.china-crusher.com/indirect-heat-drier.html
