stirring shaft for mixing high viscous epoxy and tiny metal particles evenly?

Question

Hi all...i am mixing epoxy ( viscousity 50,000 ) with tiny magnetic particles. I am using hand mixing.For small amount, there is no problem, but for larger amount I am facing some problems. most of the time metal particles are deposited at the bottom of container.It is importent for me to mix both evenly as I have to add controlled amount of magnetic particles. I can not place the shaft-end to be touching as there will be friction between shaft-end and bottom of container.but I place it as near as possible. What I need is to scoop up those deposited at bottom at certain frequency. I dont want to do it manually as the amount is large.Now I am using Anchor stirrer and still facing those kind of problems.Please recommend me some type of shaft which can mix material bottom to top..Thanks...

Answer 1

If you could make a part shaped like a propeller on the ends of your shaft it could mix the different layers together.

Answer 2

Try one of those plastic paint mixers you get at the hardware store. You can hook it to a drill. It has a long shaft and a circle at the bottom that has what looks like fan blades. With the drill you can reverse directions if you need to.
