In considerations of special features and unpredictable changes of sand rotary dryer, no one can assure that the stainless steel can solve all problems. However, in the field of drying machines, steel is still the major material for forging. The reason why we use it is based on the cost. Some large-sized drying machines can not bear high-cost metal materials. For the consideration of operation safety, some manufacturers directly install the heat source device in the bottom of sand rotary dryer. This action would be a long-term threat. Since it will cost a lot of time to remove out the heat source device, large-sized cooling system must be standby for application. This cooling system would be a potential threat for operational cost and systematic safety.

In addition, for the assurance of operational safety and high working efficiency, we need to know several factors for influencing the drying speed of rotary sand dryer. Firstly, higher the temperature and relative humidity of drying medium, shorter the drying time. The temperature, humidity and flow rate of drying medium are easy to be influenced by the property of sand materials and sand rotary dryer. Secondly, larger the contacting surface between drying medium and sand material, faster the drying speed. The lifting boards play the role of widening contacting surface.
