  Drying is a transfer process in which heat and mass transfer are carried out at the same time, and these two processes are closely related. In the drum drying operation , after the wet material forms a film on the outer wall of the drum, the contact between the material film and the outer wall of the drum is quite good. This assumption will not produce large errors in the calculation of heat and mass transfer for the drying of liquid materials, so it can be considered that there is no additional thermal resistance between the material film and the outer wall of the drum. The reason for the heat transfer of the drum dr ying equipment   consists of three parts: the convective heat transfer of the heating medium in the drum, such as steam condensation heat transfer; the heat conduction of the scale layer, the drum wall and the material film .   The convective heat transfer outside the material film. Strictly speaking, there is a laminar bottom layer formed by the vaporizat...

  In the production of organic fertilizer, the formed particles still have about 30% moisture. Excessive moisture will affect the strength of the particles, and they will be easily crushed during packaging and transportation. On the other hand, if the moisture is too large, it is easy to mold and deteriorate during storage. Therefore, the organic fertilizer should be dried in time to evaporate the excess water. The rotary drum dryer   is specially designed for the production of organic fertilizer. The whole machine is cylindrical, and a special scraping device is used inside to avoid the phenomenon of materials sticking to the equipment. The organic fertilizer dryer is mainly composed of a drum crushing dryer, a combustion furnace, a feeding screw, a discharging screw, a conveying pipe, a dust collector, an induced draft fan and a control cabinet. It is widely used in industries such as organic fertilizer, building materials, metallurgy, and mineral processing. Its production ...
