Wet type ball mill are mostly used in the industry production. It is to increase the high grinding efficiency under the ball mill grinding and striking, from which the granularity is even and no flying dust with little noise, being the most universal powder machine in the benefication as powder grinding the ferrous metal like gold, silver, plumbum, zinc,copper,molybdenum,manganese,tungsten etc, as the nonmetal powder grinding like graphite,feldspar, potash feldspar, phosphorus ore, fluorite, clay, and swell soil etc. The wet type ball mill need to add the liquid into the grinding ball media auxiliary (water or ethanol). The material output gate is trumpet shape, with screw device inside, easy to discharging the material.

an alternative ball mill - tumble tryer, er dryer. - newbie questions - apc forum

When I decided I wanted to make my own BP, I was inspired by Skylighter's article on making high-powered black powder. I wanted to make hotter powder than the commercial product we could have once got here, but now even that is unobtanium. I wanted it to be like Swiss 3Fg.

Verge collections of large rubbish are a big thing here. We go sharking, cruising the piles for garden furniture and toys for grandchildren. From an earlier one I had slabs of steel 19mm and 25mm thick for a Skylighter-style hydraulic press! Hmm, what has drive shafts and motor I could loot for a tumbler? Oooooh, a tumble dryer would also have a giant pulley for reduction!

So I thought a moment more and said why build another frame and motor mount? Just mount the white-pipe tumbler barrel inside the dryer tumbler. It took a while to think that out. MDF profiles bolted against the three ribs in the dryer drum now make up a spider to hold the barrel in the centre. I used high density foam scraps from an Ikea kids play mat to cushion the barrel in position.

Sandbags for safety? I stacked up bags of pool salt. Same price as sacks of plasterers sand, dont have to fill, and can use in the pool later. After seeing a youTube of someone letting off small explosive charges in a dryer,I found a 3' square aluminum expanded mesh for confining door explosions.

A cargo strap to hold it in axially didn't work; the strap tended to fall off around the roundness of the barrel lid even with duct tape trying to retain it. Yesterday I set bolts through the MDF profiles as lugs to run cord lashing around. I will add hooks and rubber strap next.

The dryer stops and reverses direction every minute. By my calculation this drops about 5 seconds or 8% of milling time in the toilet. Instructables.com has a couple dryer motor salvage articles, and its clearly possible to wire it differently.

I stripped the dryer and traced out the wiring, trying to understand all the switching. Having found everything I expected (and a lot I didn't expect -clever guys these appliance makers), I sketched an original circuit diagram for the machine, and thought out what I wanted. Now it has:

And for a few $ I got a 24hr time switch for the wall socket, which lets me set start and stop times for the run, at a distance from the machine. For single-ingredient milling it could be left unattended to start and end.

On this Simpson dryer the pulleys at the back had nothing to do with the drum. They run an extractor fan which is like the old blower for a forge - just radial vanes pulling air in past the heater element and through the drum, to exhaust at the top rear.

There is no ball or roller bearing setup for the drum; instead, the front and back of the drum have a 1/2" axial length cylinder formed around the opening and around the mesh of the closed end, about 200mm dia at the closed end, running in formed sheet metal rings, with a strong fabric tape between the drum and frame to separate the metal from rubbing.

The barrels I made are 150mmx150mm long sewer pipe, from the guidelines in the ball milling post, intended to mill 500g/1lb of powder at once. Balls are .690 cast, and I plan to make a cylinder instead of ball and re-cast in wheel-weights or some other harder lead alloy. The screw caps seem like a good idea but since I have to tape them I might as well have gone to end caps both ends and saved a lot of time modifying the fitting to make it short enough.

Pro tip 2: If the tumbler barrel leaks, that fan will evenly distribute a half-pound of meal across every horizontal surface in the workshop despite the best efforts of the sandbags and mesh to keep trouble enclosed.

But the lid was completely unscrewed, despite the duct tape I put around it to seal. Obviously it was not clean enough when I taped it shut and maybe not tightened down, but I didn't think that should happen!

My assessment of the cause: the tumbler barrel itself was loose in the mounting frame, and only the lid was supported by the foam packing. So the tumbler barrel was relatively free, and it just unwound from the lid under the large weight, and rotating hammering, of the ball media charge.

Chris - Just salvage the motor, purchase some pillow block bearings and shafting to match, and make something more aligned with the purpose. Dicking about with modifying a dryer drum is silly. Google "Bigg Dawg wet tumbler" for a real simple design that works.

The problem as I see it, is that I didn't use the kind if barrel and lid that Bigg dawg is using. Yes his entire design will do a great job but I am not modding the dryer drum at all, its just a cheap way to rotate a sewer-pipe tumbler barrel.

The dust was left over from the last run, in hidey holes of the MDF barrel holder that my cleaning didn't find. Frank Rizzo's recommendation looks even better, because the Bigg Dawg style tumbler is far easier to vacuum.

ball-milling: an alternative way for the preparation of anodes for lithium-ion batteries | springerlink

The preparation of new anodic materials for lithium-ion batteries is possible by ball-milling within liquid media. Those powders can be as diverse as: highly anisometric graphite particles (geometrical anisotropy around 100), graphite-maghemite ( Fe2O3) composites and graphite-intercalation compounds with high lithium contents (e.g. LiC3 is obtained by ball-milling of Li + 2C powders). These phases are the first superdense graphite-lithium compounds stable under ambient pressure and lead to a capacity of 1 Ah/g as primary battery and 370 mAh/g as secondary one. The synthesis and characterizationschemical analysis, XRD, pycnometry, TEM, SEM, 7Li NMR, magnetic measurements) are presented for each materials as well as the electrochemical behavior.
