Chemical Engineering Interview Question:

What are some common problems associated with dilute phase pneumatic conveying?

Submitted by: Administrator

Probably the most common problem encountered in dilute phase pneumatic conveying is the wearing of the rotary valve that serves as an air lock where the product is introduced into the system. If excess air is allowed to pass by the rotary valve, this can cause bridging of the material the flow can be slowed or stopped.
