[dynomike1]

I am know. last week grafe's had free shipping @ $11.99lb. Should ha ve got some. I think we are getting off early today

I can test what I am milling

to see how it does.

4hr in a Sponnen mill. 12hr in a harbor freight mill

Mumbles, how do you explain that difference?

Bigger jar thus greater falling height or what is it?

[Mumbles]

Oh no. The big jar was run on an efficient mill at around 70rpm. They harbor freight one was unmodified and ran at stock speed of around 40rpm. If I put the rubber jar on the efficient mill body, it only takes around 4hr too.

 

I was able to light the pile of meal by holding the flame to it for a few seconds. It still goes up in an instant, just doesn't catch too easily.

Would a small toaster oven with a thermostat work for drying out nitrate and charcoal.

[AirCowPeacock]

Yeah, but I've always seen dessicant as the superior option for drying. As the hydrated salt heats up, it gives up its water, which does not boil immediately--disolving the material and then boiling away. Or atleast I think this is what causes chemicals to clump after drying in an oven--for example, I've observed liquid water come out of Magnessium Sulfate Heptahydrate drying in an oven.

I dont know how much it will help my powder but i made the 3/4" mod on my harbor freight ball mill. It changed from 50rev. per min. to 88. Hope this helps my powder some. Also will be drying my ingredients.
