1. The Dosing screw is placed on the top of the system
2. Under the dosing screw conveyor, the mixing screw is receiving the material
3. The feeder screw feed a reactor tower in a chemical process

The very important keypoint of this solution is that the 2 functions are separated. During the many years of the operation, the customer has changed the pitch of the dosing screw conveyor and made some extra mixing modification on the feeder screw. These changes have been made independantly of each other. This a key point to remember in all screw conveyor design and technology – do not combine functions in a dosing screw conveyor.
