I need to know if there is a scope of installing pneumatic conveyors in these industries, and the processes where PCS can be installed.

Help Please.

Dear Ankishirani,

You can solve this problem by installing a well-designed system for venting out the rotary valve's end-clearance and circumferential leakage air. This system will maintain sufficient air flow through these passages to entrain the powder and prevent its build up.

You may contact me if you need help on the design of this system.
