    Oct 04, 2021 No matter what the direction might be, the drying air would come into direct contact with the material that is being dried. A rotary dryer is needed for both pre-conditioning and post-drying. Pre-conditioning is a drying method that is used for material before it is processed, whereas, post-drying is a method that aims to reduce the moisture

    The rotary dryer is composed of a rotating drum and a series of mechanical parts. In most cases, rotary dryers are direct-fired type, which means that the drying air comes into direct contact with the material. However, some dryers are indirect, meaning that the dryer is externally heated,it effectively avoids the contact between raw materials and drying air

    Introduction. Direct heat rotary driers are used to lower the moisture content of materials passing through the dryer. Materials are directly heated using heat from a combustion process; the fuel used is typically gas although pulverised coal, light fuel oil or waste process gasses could also be used. As the material comes into direct contact
