Sand dryers generally choose drum drying equipment, which is a mature drying equipment with a reasonable structure, easy operation, and large processing capacity. It can effectively dry and dry river sand, river sand, yellow sand, and various artificial sands. With the prosperity and development of the country in recent years and the acceleration of social construction, the sales of river sand dryers have been steadily increasing. The river sand dryer is widely used in engineering construction, road and bridge construction, and road construction. Due to its characteristics, it is also loved by a large number of users. Many users of sand dryers are unaware of the impact of the length and speed of the drum on the drying efficiency of a new sand dryer. Here, the editor of the three tube dryer will briefly introduce some knowledge of the yellow sand dryer, hoping to be helpful to everyone.

The principle of the river sand dryer is that sand enters from the feed end of the sand dryer, and the drum of the river sand dryer is a slightly inclined rotating cylinder. As the cylinder rotates, the sand moves to the lower end due to gravity. During the forward movement of wet sand inside the cylinder, it is directly or indirectly heated by hot air, causing a large amount of moisture in the wet sand to evaporate and dry, and then the finished dry sand is sent out at the discharge end. In this process, the length and speed of the sand dryer jointly determine the drying time of the sand in the new sand dryer.

The length of the drum of the sand dryer can directly affect the drying capacity, and the longer the drum of the dryer, the higher its production capacity. However, the length of the dryer drum cannot be infinitely extended, taking into account the size of the site and the heat loss associated with its length, which will also increase its fuel consumption. So when choosing the length of the drum, it's not that the longer the better, the more suitable it is. When communicating with the manufacturer, it is important to explain one's own situation clearly to facilitate technical personnel in configuring the appropriate length of the dryer drum.

The speed of the sand dryer drum determines the drying time of the sand in the drum. The higher the speed, the shorter the time the sand stays in the drum, and the corresponding drying time will also decrease. If the moisture content of the sand is low, it is possible to increase the speed of the drum while ensuring the drying standard of the sand, which can effectively improve work efficiency. If the moisture content of the sand is high, the speed of the drum can be reduced to increase the drying time of the sand in the drum, so that the material sand can reach the moisture standard that can be dried.
