Introduction: K'nex Ball Mill Very Easy
I need a ball mill to make aluminum powder for thermit so I made this. I used K'nex because I have a lot of them and they are easy to use.
Step 1: Materials
You will need the following. 1 medium sized mayo jar or any other round jar. If you do use a different size jar you might have to change the frame a little because it is coutom to the jar I had. You also will need so marbles or steel balls. I used 23 but it doesn't matter. You at least need 20. You need a big motor. I got mine from a treadmill. Last you need is a rubber band some aluminum foil and of course k'nex.
Step 2: Motor Base
Place grey rods through holes on the base of the motor a should lock into the white rods.
Step 3: Base That Holds Up Mayo Jar
Build put together
Step 4: Putting It Together
Just clip the rods on
Step 5: Finnish and Use
Have fun be safe and please vote. Also it will take a day or two of running before the aluminum foil becomes powder.
