During the operation of the sludge rotary dryer, sometimes the blockage of the sludge dryer is caused by customers neglecting details. If the temperature at the furnace mouth significantly increases, it is highly likely that the drying equipment has become clogged. What are the reasons for sludge dryer blockage? How to handle it?

  1. The material has a high moisture content and viscosity

  When the moisture content of the material is too high, it is easy to agglomerate during the drying process, affecting the feeding efficiency and even causing the material to be blocked or obstructed. In this case, we need to strictly control the moisture content to prevent blockage. If the viscosity of the dried material is too high, it is easy for the material to adhere to the inner wall of the drum after entering the dryer. The longer the time, the more material adheres, which can cause blockage. Therefore, for high viscosity materials, we need to clean their interior to avoid sticking the material.

  2. Insufficient heat in the drying equipment

  The drying of materials is mainly carried out under the action of heat transfer. If the heat inside the rotary dryer is insufficient, the moisture in the high humidity material cannot be quickly removed, thereby prolonging the residence time of the material in the drum and easily causing material blockage. Therefore, ensuring sufficient heat and stable temperature is one of the key factors in preventing blockage.

  3. The air duct of the dryer is blocked due to poor sealing

  After using the drying equipment for a period of time, the wear and consumption of accessories can also cause slow drying of materials or blockage of dried materials. It usually operates under negative pressure. There should be no gaps at the connections between the drum, components, and fixing devices. Some parts should be equipped with sealing devices. If the sealing device ages or falls off, it can also cause air leakage. If the material flow is not smooth and the drying is not timely, it can also cause material blockage.

  In summary, there are many reasons for the blockage of rotary sludge dryers. We should start from two aspects: pre prevention and post remediation. In daily use, timely cleaning of internal adhered materials and regular maintenance should be carried out. If there is a blockage, analyze the reasons from multiple aspects and solve them one by one.
