Sand dryers have advantages and disadvantages.
The advantage of the sand dryer is that the moisture content after drying is small, the price is cheap, the floor space is small, and the color is good after drying. These are the advantages of sand dryers, although there are many advantages, but there is still a gap between them and the advanced level abroad.
Sand dryers have a drawback, which is a fatal flaw. It is possible that the inside of the dryer may catch fire. It should happen inside, and it is not easy for the staff to find the inside of the fire under normal circumstances. One thing that is very serious when the inside of the dryer is on fire is that the internal sand is burnt, and the use value is lost and becomes waste, causing serious waste.
The reason for this shortcoming is that the drying medium of the domestic dryer is obtained by heating the cold air from the hot air heater. Cracks may occur between the end plates of the heat exchanger and other devices due to prolonged heating, corrosion, and aging. At this time, the fire may cause the sand to catch fire as the medium enters the inside of the dryer.
Of course, things like this happening are small. China's research on sand dryers will continue. I believe that with the development of science and technology, we can solve this problem very quickly.
