Nitrotitanite Posted January 7, 2017 Share Posted January 7, 2017 (edited) Hello guys, today I made a small batch of BP but I realized that I had finished alcohol to make my usual procedures.In the absence of ball mill I arrange with a good blender 700watt.Unfortunately this forces me to make a passage for partial recrystallization before passing a second time in the blender then fine sieve and graining.But this time I added only so much water and shake for 5 minutes then in a convection oven at 80C ° until complete driyng,and a fast passed into the blender.BP which is output is one of the best that I came out taking realize that the process is only halfway.It is possible that the good quality of the BP in the video is due to the purification of potassium nitrate occurred in the oven? Being a beginner are very enthusiastic and all your opinions or criticism for me is gold. videocompress-046-myVideo.mp4 Edited January 7, 2017 by Nitrotitanite 1 Link to comment Share on other sites More sharing options...
Boophoenix Posted January 7, 2017 Share Posted January 7, 2017 Nitro, I certainly hope that you're running individual materials threw the blender not a mixture of them? 1 Link to comment Share on other sites More sharing options...
austar Posted January 7, 2017 Share Posted January 7, 2017 Try screen mixing, wetting and useing a pot or frying pan on low heat to dry out. It turns into a hard ball and still appears still wet. Let it sit for a couple of minutes then rice. It will only take a hr or 3.Works for me.Just gor the hope of god dont use the blender on anything but individual ingredients.

MrB Posted January 7, 2017 Share Posted January 7, 2017 Nitro, I certainly hope that you're running individual materials threw the blender not a mixture of them? Sounds an awful lot like it's the dried product he's running through the blender.There is so much wrong with this approach, that i don't really know where to start. The oven. The heating elements in it, gets way past the ignition point of BP, so it's at least a fire hazard, probably a explosion hazard.Blade milling BP t reduce it's particle size, is at the very least, a friction nightmare, and a explosion waiting to happen. If criticism is gold or not, i don't know. But PLEASE. For the love of anything you see as sacred. Life, god, or the reputations of pyro-hobbyists. Stop this, at once.B!

Nitrotitanite Posted January 7, 2017 Author Share Posted January 7, 2017 (edited) Is in effect the last step I do it in the blender without the lid opened only with a kitchen foil.In theory without cover in the event of power it would form only a blaze but not an explosion, and its because of the outburst, at least in theory.I know it's an unsafe method and would not recommend it, but I did not think it was so risky.You say that a explosion be possible? I state that the longest passage in the blender BP is a liquid slurry dry passage is of very short duration.I will get to work for the ball mill as soon as possible.

Boophoenix Posted January 8, 2017 Share Posted January 8, 2017 At least you're aware of the danger and accept it. Personally I would not attempt it and would work towards the ball mill harder, but that's my perspective. If you're not getting good hot BP then you are not quite as dangerous to yourself. I can't comment on that, but if it's getting near good hot BP you may risk rumpturing the container causing fragments which would be more dangerous than the flame exposure. Even though blenders hold liquids well I've noticed powder residues from little rocket blender uses. Should this happen with your larger blender you might compound the friction issue and other risks. Don't forget while it involved a mill of individual components Dave F. produced a perfectly serviceable BP from screen mixing. Blender your individual components and just use a little more BP to offset any lack of power. The only places you might have trouble with that option may be rockets to a small degree or breaking small a shell. For the shell add a booster if ya need to over a risky process might be something to consider. Link to comment Share on other sites More sharing options...
calebkessinger Posted January 8, 2017 Share Posted January 8, 2017 For your own safety.. Please don't put bp in the blender. Some of us here have seen the burn units at the hospital for one reason or another. It just takes an instant. We will gladly help you get perfectly usable bp if you give us a day or so to understand what components you have and help you get the most out of them. 1 Link to comment Share on other sites More sharing options...
Nitrotitanite Posted January 8, 2017 Author Share Posted January 8, 2017 Thanks guys for all your advice and moniti.È true the incident with this method is just around the corner for a moment and booom and your life suddenly changes.Certainly not worth it to risk so much for laziness to build a mill.Meanwhile he devised a remote control to activate the blender, with a servo motor for models with radio control outdoors and at a distance of security.for the moment will follow this procedure limiting the risks to the maximum.I am, however, already preparing a draft for the construction of the mill already ordered the ball bearings on Amazon at a great price.

Nitrotitanite Posted January 8, 2017 Author Share Posted January 8, 2017 In your opinion what is the best material to use for grinding balls?Excluding clearly metals that can cause sparks and even the glass that may emit piezoelectric discharges. Unfortunately for me anti spark plummet spheres do not find them, I would be routed on ceramic balls or even better brass balls.Thanks to all guys from the responses it is clear that you are wonderful people.

Mumbles Posted January 8, 2017 Share Posted January 8, 2017 Lead is usually preferred, but brass would be fine too. Not all ceramic is suitable so be careful there. Link to comment Share on other sites More sharing options...
Nitrotitanite Posted January 8, 2017 Author Share Posted January 8, 2017 Ok Thanks then I will use the brass balls. Link to comment Share on other sites More sharing options...
Boophoenix Posted January 8, 2017 Share Posted January 8, 2017 If you happen to look at lead you'll want a hardened lead not just plain lead. Caleb could give you some more input on it since he makes lead. I bet Mumbles has some details as well if not many more here too. Link to comment Share on other sites More sharing options...
Arthur Posted January 8, 2017 Share Posted January 8, 2017 (edited) If you must use a blender for powder you need to find one that will work at the end of a long wire so that you can operate it remotely. switching it on and off from 50m away is better than direct operation, but still accept that it will explode sometime but that it will be far enough away. Addedthat means 50m+ away from anything or anyone! Edited January 8, 2017 by Arthur Link to comment Share on other sites More sharing options...
Nitrotitanite Posted January 8, 2017 Author Share Posted January 8, 2017 Certainly the area is protected by stone walls in the event of an explosion would not be involved no one and no objects.To think that I did the steps with the blender in his hands on him you have warned me I shudder behind his back.
