The type, nature of the material (such as loose, not easy to clog, etc.) and water content will directly affect the choice of dryer.
The moisture content and yield requirements required for the dried material are also important factors in determining the size of the three layers rotary dryer machine.
2. Three return ‌dryer technical parameters:
The outer cylinder diameter, outer cylinder length, cylinder volume and other parameters are directly related to the processing capacity of the dryer.
Cylinder speed and maximum intake temperature will also affect the drying efficiency and effect, thus indirectly affecting the size selection.
‌Evaporation intensity and residence time:
3. The evaporation intensity of water, that is, the average quality of evaporated water per square meter of effective volume per unit time, is an important indicator of the performance of the dryer.
The residence time of the material in the rotary dryer cylinder body will also affect the drying effect, which is closely related to the size and structure of the dryer.
4.‌ Space and budget considerations:
The size of the space to install the rotary dryer will limit the maximum size of the dryer.
The budget is also an important factor in determining the size of the dryer, and the price of different sizes of dryers will vary.
To sum up, the selection of the appropriate three-return dryer size requires comprehensive consideration of material characteristics, drying needs, technical parameters of the dryer, evaporation intensity and residence time, as well as space and budget. Through a detailed analysis of these factors, combined with the actual production needs, the most suitable three-return dryer size can be selected.
