In the actual use of sand dryer, there are many factors that affect its output, and ventilation volume is one of the more common ones. So how does ventilation volume affect output? It can be understood mainly from three aspects.
First, in the process of sand dehydration and drying, the dehydration and drying effect of sand is mainly achieved through heat exchange between wet sand and high-temperature airflow. If the ventilation volume of the sand dryer is too large, the sand and hot air in the dryer drum will be sucked away before they can fully transfer heat and mass, which will seriously affect the dehydration and drying efficiency of the sand, not only greatly reducing the output of the dryer, but also increasing fuel costs.
Second, if the air volume inside the sand dryer is too small, after the sand with high humidity and the high-temperature airflow have fully exchanged heat, the humid hot air in the dryer cannot be sent away in time, which will seriously affect the dehydration efficiency of the equipment, thereby reducing the output and affecting the quality of the sand after dehydration. Therefore, adjusting the appropriate air volume of the equipment is a key factor in ensuring the working efficiency and quality of the sand.
Third, during the operation of the sand dryer, uneven feeding by the staff will also affect the ventilation volume of the equipment. Because if the staff feeds too much material to the drying equipment, the sand cannot be fully contacted with the hot air, resulting in incomplete dehydration, which affects the output and quality of the equipment. At the same time, if the feeding is too little, it is easy to cause the dryer to break, resulting in a large loss of heat and increased fuel costs.
Therefore, in order to ensure that the sand dryer has good working efficiency and high output, when using it, it is necessary to adjust the ventilation volume of the equipment, and feed it strictly according to the feeding requirements to ensure that the drying is more complete.
