How to choose the capacity and size of sand dryer according to production needs?

Sand dryer is a kind of equipment specially used to reduce the moisture content of sand. It evaporates the moisture in sand through heat transfer, thereby increasing its calorific value and facilitating transportation and storage. The equipment usually adopts a rotating cylinder design and can handle a large amount of wet sand. How to choose the capacity and size of sand dryer according to production needs?

1. Processing capacity requirements. First determine the scale of the dryer according to the daily or hourly processing capacity of sand. Make sure that the selected equipment can meet the expected production efficiency, avoid being too small to meet the production plan, and too large to cause resource waste.

2. Material properties. The physical properties of sand such as initial humidity, particle size distribution, and viscosity will affect the drying efficiency and the required drying space. The higher the moisture content, the greater the drying time and space required, and the length and diameter of the sand dryer cylinder should match it.

3. Site restrictions. Consider the actual space size of the installation site, including the floor space of the equipment itself, as well as the layout requirements of supporting equipment such as feeding and unloading equipment, heat source supply, and ventilation system.

4. Economic benefit analysis. Considering the one-time investment cost and long-term operating cost, choose a cost-effective dryer, and also pay attention to the performance in energy saving and environmental protection.

5. Drying requirements. According to the moisture requirements of the sand product and the quality standards of the dried material, determine whether the sand dryer needs to have special functional design and control technology.
