Of the different types of dryers that there are the most common is the ROTARY DRUM DRYER/Kiln, This type of drier is common not only in the mining industry but you will find them in fertilizer plants, Cement plants, and peat hogs to name but a few.. The theories behind these machines are very simple, heat an air space up, and then tumble the material to be dried through this space until it is ...

If you bought a used dryer or one without its user manual, the capacity still can be calculated. You can't tell a dryer's capacity from its external size alone. You must take the measurements of the interior drum that holds the clothes. Once you have the right measurements, you simply calculate the volume to determine how much space is in the ...

Retention time, also called residence time, is the amount of time that the material must be processed in the rotary dryer in order to achieve the desired results.. The retention time required for a given application is determined through balancing the necessary process parameters – particle size distribution, air flow velocity, temperature, and more – with the desired outcome; it can then ...
