How does the Special paddle dryer for sludge dryer products work
The Special paddle dryer for sludge dryer products rotates slowly under the drive of the transmission system, the material enters the machine from the feed port, and is transported to the discharge port through the slowly rotating Special paddle dryer for sludge dryer products. During the conveying process, the material is heated and dried by the hollow blade and the jacket at the same time. Since the hollow blade is wedge-shaped, the material is alternately compressed (at the wedge-shaped slope) and expanded (at the wedge-shaped gap) during rotation, so that the material on the heat transfer surface moves violently and strengthens the heat transfer surface. Cleaning effect, thereby greatly improving the heat transfer coefficient. The heat medium used for drying can be steam, heat transfer oil or hot water. The heat medium enters the hollow shaft and the paddle through the rotary joint. When the heat medium is changed to cooling water, the machine is an ideal powder cooling equipment.
Special paddle dryer for sludge dryer products What should I do if the finished product is unevenly dried? The problem should be attributed to the wrong adjustment of the rotational speed and drying temperature. Most of the ingredients are moist and sticky, so briquettes can easily form. The function of the rotating drum is to disperse the briquettes and make them independent. If the drum speed is not adjusted properly, the briquettes are not easy to disperse. Therefore, the dryness of the finished product will be somewhat uneven.
Since the material itself has no fluidity, the material in the Special paddle dryer for sludge dryer products is pushed by the blade and its own gravity. Therefore, in order to make the material flow in the dryer, in order to meet the characteristics of various materials and drying processes, the structure of the paddle dryer is various. Common ones are: indirect heating paddle dryer, hot air paddle dryer, vacuum paddle dryer, hollow paddle dryer and other forms.
