How to determine whether the rotary feeder has emptied the material level?
Thread Content
The discharge system below the cyclone separator originally used a pressure screw to push the solid powder into the injector, with the airflow from the Roots blower being used to transport it to the storage bin. Now our manager wants to replace the screw feeder with a rotary feeder. My questions are: 1. There is no level gauge inside the cyclone separator (crystallization easily occurs inside the cyclone, resulting in inaccurate level readings); how can we determine whether the material level inside the cyclone has been depleted? 2. With an internal and external pressure difference of 0.3 MPa in the rotary feeder, can it seal the gas inside the cyclone to prevent it from leaking out? (The rotary feeder from Shanghai Hanrui is planned to be used)
0.3 ah. Ours is 0.03; it seems a bit more stable than yours, hehe~ High pressure causes air leakage...
In the first stage, it is determined whether the material seal has been broken based on changes in the discharge temperature and the outlet pressure of the Roots blower. Can this same method still be used if a rotary feeder is employed?
