I already built a survey,  it should consider below things then send a Survey through Survey Invitation Quick action On Process Builders.

Considerations to send Survey upon Case Closure:

If a Customer has just completed their first Case, we wait 10 days before sending them their survey.
If a Customer has responded within the past 30 days, we do not send them a survey for that Case. 
If a Customer does not respond to a previous survey we ensure 10 days have passed since the last survey was sent and send another when the next Case closes.
