Flash dryer poor feeding solution flash dryer encyclopedia

Mondo Science Updated on 2024-02-06

When the flash dryer processes the cake-like material, it may encounter the problem of poor feeding. This is usually due to the formation of a bridging of the material above the screw conveyor shaft, causing the conveyor shaft to run dry. In order to ensure the normal operation of the flash dryer, we need to take a series of measures to solve this problem.

First, the problem of material bridging.

When the cake-like material forms a bridge above the screw conveyor shaft, the operator should break the bridge at the first opportunity. This ensures that the material can enter the hopper smoothly and avoid the idle running of the conveyor shaft. In order to prevent the occurrence of bridging phenomenon, it is recommended that the diameter of the filter cake block entering the feeding hopper is less than 10cm.

Second, the problem of miscellaneous mixing.

During use, it should be regularly checked whether there are impurities such as metal iron sheets or coarse long fibers mixed between the spiral blades. Once an abnormality is found, the screw conveyor should be reversed immediately to exit and remove the debris. This prevents debris from causing damage to the spiral blades and ensures the normal operation of the conveyor.

Third, the problem of material solidification.

The solidification of the raw material in the screw conveyor may also cause the conveyor blades to be unable to push the material. Therefore, it is necessary to regularly check whether there is solidified material inside the conveyor. Once a similar situation is found, the solidified material should be removed in time to ensure the smooth operation of the conveyor.

Fourth, the motor or parts do not rotate.

When the motor or parts do not rotate, you should first check whether the power cord is falling off and whether the coupling connection screw is falling off. These problems may cause the motor or parts to not work properly. Once these problems are found, they should be solved and dealt with in time to ensure the normal operation of the equipment.

In short, in order to ensure the smooth feeding of the flash dryer, we need to pay attention to the problems of material bridging, debris mixing, material solidification, and motor or parts not turning. By taking appropriate preventive and solving measures, we can ensure the stable operation of the equipment and improve production efficiency.
