Many users report that the efficiency of the lignite dryer is not high. How can we improve the lignite combustion rate of the lignite dryer while ensuring the drying quality? The professional manufacturer of Zhengzhou Jiutian Lignite Drying Machine has been constantly exploring and innovating from the user's point of view and has summarized the following methods to improve the lignite combustion rate of the lignite dryer:

  1. Choose a heat source device suitable for users and with high thermal efficiency. The heat source coal loading method adopts automatic equipment to reduce unnecessary heat loss caused by manual coal loading.

  2. In order to control the temperature of drying, thermocouples are installed on the feeding and discharging device, and the temperature change at the feeding and discharging ends of the lignite dryer can be displayed through the thermometer, which provides a basis for better control of the working temperature in the cylinder.

  3. For the contact between the drying medium and the material. Effectively increase the contact area between the drying medium and the material in the working process, which can increase the drying rate.

  4. The material that needs to be dried flows from the feed box and the feed into the cylinder, that is, it is pushed back by the spiral plate. Due to the inclined placement of the lignite dryer, the material flows to the rear under the action of gravity and rotation. On the other hand, the material is repeatedly picked up by the copy board, brought to the upper end and then continuously spread down, so that the material forms a uniform curtain in the cylinder, which fully exchanges heat with the hot air flow in the cylinder. As the material is repeatedly scattered, the moisture contained in it is gradually dried to achieve the purpose of drying.

  5. Choose the most reasonable internal structure of the drum and drum rotation speed to make the material evenly distributed in the dryer with less heat loss.

  6. The temperature, humidity and flow rate of the drying medium are affected. If the temperature of the drying medium is higher, the relative humidity will become smaller, and the higher the flow rate, the shorter the drying time will be.

  7. Strengthen the inspection of the dryer to prevent air leakage.
