Calculating screw conveyor flowrate
Please assist with a formula for calculating flow rate. There are charts available, but we need to know the loading that you desire, the size of the screw conveyor, the pitch of the screw conveyor. Then the charts will give capacity of cubic feet per hour per rpm. You can then use this up to a "maximum economical speed".

The Shaftless Spiral Conveyor: A Unique Approach to …
In contrast, the shaftless spiral (screw) conveyor operates without a central shaft. Instead, it features a spiral-shaped screw running inside a trough. This design proves particularly advantageous when handling sticky, viscous, or irregularly shaped materials that could lead to blockages or entanglement in a shafted conveyor.

CNC Feeds & Speeds Formula (How to Calculate Feed Rate)
Feed rate = RPM x chip load x number of teeth. This formula gives you feed rate in IPM or mm/min based on whether you used the metric or imperial table. If you prefer to use cutting feed (IPR) instead of feed rate, you should remember not to multiply by RPM. So, cutting feed = chip load x number of teeth.
