While, if sand dryer is equipped with the hot air in direct way, product quality will be seriously influenced due to the dust pollution. Based on the way of direct heating, thermal efficiency of river sand dryer is very high. The way of direct heating should be given preference if the product quality is not easy to be influence by dust. Hot air furnace, driven by the thermal dynamo, can be the ideal alternatives of electrical source and traditional steam source in many industries.

With hot air as the drying mediums, sand dryer can have great thermal efficiency and working performance.
