memo Posted September 30, 2019 Posted September 30, 2019 (edited) this is about 4 hours in making 3600 red 1/4 inch cores. there has to be a better way. watched a video by pyro hook putting drops of water on dry comp in his star roller. looks to be a lot faster. any body tried this ?

Arthur Posted September 30, 2019 Posted September 30, 2019 I saw Kimbolton making cores, Put lots of powder in a star roller and make a coarse spray of water and roll til the droplets close up as cores, screen and repeat til the powder is gone. Much of the technique of star rolling is the control and choice of the sprayer(s) A coarse spray makes cores, a fine mist helps cores to grow. 1
Arthur Posted September 30, 2019 Posted September 30, 2019 Probably the best tool kit is a selection of sprayers some that make coarse and fine droplets, some that make mist and fine mist.

Mumbles Posted October 1, 2019 Posted October 1, 2019 Ive done the water droplet core forming thing. I'm not claiming to be an expert by any means though. It's hard and easy at the same time. It's a procedure you just have to kind of go for. What I mean is that you can't really baby it. You just have to add in the water continuously and with some blind faith. I'm better versed at getting more granule sized grains instead of larger cores. Once you get there it's just a matter of giving it a little more time or a little more water. The biggest thing is that this works better with larger batches. You need a certain amount of mass in there to help things build up and keep from sticking together. As a gut feeling, I'd suggest no smaller than 10lbs. Maybe 5 lb if you're trying to keep things small or have some experience. Worst case scenario, you can always take the batch and dry it out a bit and then pump them. You want to add somewhere in the ball park of 14-16% water by mass. Something like a pump garden sprayer is usually fairly controllable and is much easier on the forearms than a bottle mister.
Arthur Posted October 1, 2019 Posted October 1, 2019 As an alternative. Get an icing pump or bag from a supermarket, (used for cake decorating) and make lots of thin lines of pumped comp, then cut these into small pieces while damp, with a knife. 2
memo Posted October 1, 2019 Author Posted October 1, 2019 cores are done and i was ready to roll the 2nd layer. getting ready to mix the comp and i have no airfloat . since i sold the hotel and moved my shop into a 20 ft. sea canister things are not easy my ball mill is a double rebel 17 and the box that is the blast protector is 3/16 steel a 2 person job. well in the morning I can get to work
