Just thought of an idea for a ball mill motor. Would one from a food mixer (not processor or blender) work? Just wondering if it would be able to keep going for a few hours becuase I would not have to bother with gears.

It might do...A mixer motor will probably have a higher torque than a blender motor. Why don't you just use an old motor from a second hand washing machine?

I am considering. We have one-just got to ask pops if I can have it.

Well I finally made my ball mill. Cost me nothing, the milling jar and media were the only things that I payed for. I got the idea to use a desk fan motor, its holding up well. I have it "geared up" with direct drive. I got a sleeve and put it over the roller and the motor. My first batch of proposed "good meal" has been going for 1 hour, only 3 more to go I would take photo's but my computer has shat itself so im on our living room computer which doesnt have all the gear I need, perhaps it will get its act together by tommorow.

nice one Matt. i wish i tryed my fan motor. hows it holding up?

[Matt]

Oh man milled things are awsome. All i need now is some better charcoal, I think I still have some hacked up grapevine in my shed. My video camera is working now so all he video's on my site wont be so big from now on, and you wont need quicktime....... god damn mac's

Well, finnished my first Ball Mill and without a dout, it is THE most successful bogge job ever. I set some caster sugar to mill for an hour and it came out like flour! Not bad at all but will have to invest in some cooling for the motor. It's a car wiper motor BTW. The media was brass nuts with lead casted into them. Although the container wasnt half full of them, not bad for about 100g of sugar. Will take some pictures tomorow as its 22:10 here and I am tired.

BTW The motor runs from a car battery so I can stick it in the field out of trouble!
oh and what does other peoples milled chems come out like (flour or finer)?

like flour but kind of fluffy, very low density, perhaps a microscope can help to class particle size

You may want to check on the temperature of the wiper motor as they are not designed for long running time high torque applications. Should be fine as long as you keep an eye on the temperature.

True that they are not designed to be run for a long time on high torque but it doesnt complain to much after 2 hours milling. I made some Chlorate BP today as GD have yet to send me a catalogue but I will call them tomorow. Gets quite hot (about 70-90 degrees) but I will buy a computer case fan and stick that onto the battery as well. The battery ran for 2 hours no complaints so its a good working ball mill so far. The guy next door to us says that it should be OK (the motor that is) and he knows his ABC when it comes to cars and their parts, he's been working with them for most of his life and he's about 65+

dont like the way you mention making chlorate BP and ball milling in the same text. you didnt mill the CBP did you?...had to ask...

[Stuart]

Too late! Lost some fingers!

And I thought using a tumbler was crude

LOL, I works though
