Material in the presence of moisture in the air dryer temperature state to speed the flow of hot air in the drying tube, the residence time is very limited, therefore, generally apply only to material non-binding constant drying process water surface evaporation. Practice shows that, under these conditions the presence of moisture laboratory airflow dryer, granular materials can be designed in a dryer drying gas air drying tube and, ultimately, a water content of 0.3% to 0.5% of the product. For as the diffusion of moisture migration within the material wet material is completely inappropriate for air drying process. Low sodium carnallite in the use of impulse drying equipment for dewatering, process parameters, air pressure flow parameters dryer air drying equipment inside the tubes must be adjusted to a slightly positive pressure or positive pressure airflow travel dryer, so as to ensure the quality of low-sodium dehydrated carnallite. However, when the pressure inside the pipe is slightly positive or positive pressure, the inlet vent out, even if i screw feeder sheet feed force, blowing into the mouth of the materials division everywhere, polluting the environment. Because of the hot air out. Spiral feeder spout wall could easily lead to material sintering blocked spout and screw feeder bearing burned and other mechanical failures. Can lead to continuous production and downtime rate is too high, thus affecting the product yield and quality. In order to solve the difficulties of feeding device into the inner problem, design and manufacturing flow ejector.
