Hi, I have recently made some sulphur less BP to see how it performs instead of ball milling it I decided to use the CIA method, I decided to use the CIA method because I was using balsa and it doesn't mill very well.

First of all I weighed out 80 grams of KNO3, 10 grams of balsa charcoal, and 10 grams of radiata pine charcoal.

Secondly I placed 400ml of methylated spirits into the freezer to cool down for 3 hours.

After 3 hours I placed a small pan on the stove with 20ml of water, and heated it until boiling temp was reached. Then dumped in my 80grams of KNO3 and added more water until it was all dissolved.

I then proceeded to add in my charcoal witch took a ridiculous amount of time to get incorporated into the liquid because of surface tention with the balsa.

After it was all incorporated I removed the 400ml of methylated spirits from the freezer and placed into an empty ice-cream container. After stirring the mixture on the stove for 2-3 minutes I quickly dumped the mixture into all the methylated spirits cooling it as fast as possible. Placing the ice-cream container back in the freezer for 1hr stirring every 10 minutes it was about 10 degrees c when I placed it into the freezer.

After 1hr I removed the ice-cream container from the freezer and strained this mixture through a fine piece of cloth and squeezing out allot of the liquid, I tried my best to get as much as I could of the mixture into the cloth (which was practically all of it)

After granulating through some fly screen and onto some newspaper I set it aside to dry for 1 day.


Now heres my problem In theory with 100% perfection I should have ended up with 100grams of powder, allowing 10 grams to be lost through filtration ETC, so leaving me with around 90 grams, onto the scales I had a dismal amount of 50 grams.

Now how can I possibly loss 50 grams of powder because I definately know that I didn't lose that much through filtering.

Allright, I recently got myself a washing machine motor for a ball mill.
The problem is that I don't know how to connect it to main power, It has 5 wires coming out the side of the motor. The colour of the wires are Black, Red, Brown, Dark blue, and a Brown wire with a black line spiralling down it. So what do I do .
I thought maybe that I use the red and black wires for +/- is this right or wrong.
