In the processing technology of organic fertilizer production line, many technological processes need to use organic fertilizer equipment – that is the Organic Fertilizer Rotary dryer. How does the Organic Fertilizer Rotary dryer realize the drying and drying process in the organic fertilizer processing process? In short, The drying of organic fertilizer is realized by two processes of direct or indirect drying. There are many manufacturers of organic fertilizer Rotary dryers. In the following article, we will recommend manufacturers that are very suitable for organic fertilizer processing and drying.
Rotary Dryer drying process:
The drying process of wet material in the Rotary dryer is a process of comprehensive transfer of heat and mass inside the material and in the boundary layer between the material surface and the drying medium. Under constant convection drying conditions, hot air flows around the wet material, thereby transferring its own heat to the wet material, and at the same time taking away the water vapor evaporated from the wet material, so as to achieve the purpose of drying.
Drying temperature for different applications of organic fertilizer Rotary dryer:
The organic fertilizer Rotary dryer can be used not only in the organic fertilizer industry but also in other industries. When drying other materials, it should be noted that different materials have different requirements for drying temperature and other process conditions. For example the following:
1. When the organic fertilizer Rotary dryer is drying the clay, in order to maintain certain plasticity, the drying temperature of the clay itself should not be higher than 400 ℃ to prevent the dehydration of the kaolin.
2. When the organic fertilizer Rotary dryer is drying the slag, in order to maintain the activity of the slag and prevent the occurrence of devitrification, the drying temperature of the slag itself should not be higher than 700℃.
3. When the organic fertilizer Rotary dryer is drying coal, in order to prevent the volatile matter in the coal from escaping, the drying temperature of the coal itself should not be higher than 200℃.
Therefore, in order to obtain high-quality finished materials and high drying efficiency, it is very necessary to have a clear understanding of the drying temperature of the materials.
Organic fertilizer Rotary dryer drying mode:
The two drying methods of the organic fertilizer Rotary dryer are the direct drying method and the indirect drying method. The direct drying method uses a heat carrier such as high-temperature gas to directly contact the material, which can make good use of combustion. Heat energy, to achieve the purpose of reducing production costs, the water vapor when the material is dried will also be directly discharged with the gas, which is convenient and fast. However, the disadvantages of this method are also obvious. If the chemical properties of the material are unstable and cannot be directly contacted with the hot flue gas, it will contaminate the material and cause material pollution.
Another method is the indirect method. The indirect method, as the name implies, is to allow the material to be indirectly heated through the heat transfer medium, and the utilization rate of heat energy in this process will be correspondingly lower. Because of the loss of heating heat transfer medium. However, it can ensure that the materials dried by the tumble dryer are purer. Therefore, which method to use, customers should screen according to their actual situation.
Organic fertilizer Rotary dryer manufacturers recommend:
The organic fertilizer Rotary dryer plays a very important role in the granular organic fertilizer processing production line. Here we recommend Zhengzhou Tianci Heavy Industry Organic Fertilizer Rotary dryer manufacturers, which is a professional manufacturer of organic fertilizer production line process equipment. With 20 years of processing experience, it is also one of the few manufacturers that can manufacture a full line of organic fertilizer equipment. The organic fertilizer Rotary dryer it produces has a dust suppression device that is environmentally friendly and clean. The equipment is of good quality and is a trustworthy and purchased organic fertilizer dryer.
