Ball Mill construction
I have prepared the ball mill which is looking into the picture I found online. This simple device is running the container in which approximately 1 / 3 of the completed granular material (testing used the cat litter), and something every material crushed in powder. Here's how to make my own mill. Here, no map, only the explanation of that course of action in order to achieve the final result.
From the outset, to take part. I had an old 3 / 4 hp 1 / 2 "axle of the engine which had a 1-1/2" diameter circle. When about 6 "diameter disc and 24" long axis of which was suitable for 6 "disc. A little wood, one more circle around the 1 / 2 and 1" in diameter .. The same length (2 feet). Engine belt not too short, but not 32 feet (unless the have a large workshop). Screw, nail, clamp, oil, a little rubber hose which is well adherent to the middle axis of the disc. And required the vessel to which I used a circular plastic gallon jar of pickles. One of those used in the food industry and restaurants. Nothing special, he just had a smooth sides and a wide cavity with a screw cap. Then, the measurement of the length to make sure that my second will be available in sufficient time. Then simply make frames and affix it to the wood chips. Did it 4 inches wider than the container. After 2 inches on each side!
Frame length depends on where the engine will be mounted and the length of the belt have. If in doubt, do as far as possible, a longer (though 5 feet, if you have a long belt!) Mine about 22. "Driving shaft to keep the column with production now recount.
The pillar is made of 2x4 off-block at approximately the size as the diameter of the drum. May be slightly longer, it is not important. Before fitted to the frame, they need to drill holes axis. Used the 5 / 8 "First, because this size was a disc of my hole. Therefore, drill 5 / 8" holes. Tighten the two push blocks, and drilling through both at once, in order to get a smooth, straight holes.
Drill holes can be collected driving shaft. As I have already said, uses 5 / 8 "First, because I found the following dump. Do not thicker than 1" axle, the rotation speed, which are described later. Pulley 6-1/2 "diameter with 5 / 8" hole. Done at the axis is longer than necessary, because the equipment is simple, here are used hold the rings, or bearings, the second option is to slide - which does not preclude full. Worse would be if it would be too short. 5 / 8 "axle was easy to find rubber slang with 5 / 8" internal diameter. Slang being cut so that the length is equal to the inner frame width, 3 ", even after deduction coli ends. Being cut over the first floating too freely and too little - slang stalled between the columns.
In other words - column here unnecessary, because the metadata does not allow it to slide out.
And using oil stained media, no need of bedding
Now you need to slang planted on the axis, which is much easier said than done! It should be the axis of the center. Used the WD-40 lubricants, as well as the order was both saliva (know, FU!) But that it was put, I used 3 / 4 "inside diameter pipe and a hammer. Now, for the slang should be removed and sliced.
Now you can put blocks on the line and nail the frame (I do not think that the bolts here will). Kalanta attach them to push as far as possible directly. Next, attach the disc on the rear axle on the side of the engine and the pulley and attach the screws. Now turn to check whether the axis of the holes drilled directly. Should rotate not bad. If not, Get blocks, remove the axle and slightly increase the holes. This is not complex ..
Next Step - engine accessory. Placing the belt on a disc engine built on the platform, and had mounting holes, after the removal of belts and motors, drill holes, I used 5 / 16 "bolts engine consolidate.
Distance to the engine depends on the length of the belt. (I've used a belt.) Approval of the engine, make sure that the size of the platform allows tensioning seat belts. Attach the engine so that Pulleys stand parallel. Pulleys parallelism may be able to determine from the eye. Negligible margin of error should not affect, as the first, and to some extent for floating, so a bit wrong.
Now you have another pair of shoes mounted on the other axis to hold the container from the other side. It is produced as well as the first drive, the difference is that it rotates freely rotate the container. To attach asi straight, turn on the ball mill'a the frame affix thrust blocks, find the place where the best mounted on a rotating first, then nail blocks to the frame.
Axes of the tree hole driled so they should be soiled oil. I drill holes from the top boards to the axles holes. From time to time then pour the oil. The holes small enough that the oil complies with the capillary effect, therefore lubrication way to act longer.
If the devices improved, you can use the bearings, wheel or someone who you think it helped. I used double-sided tape on the jar, and improves the adhesion between the jar and turn the axle.
Now simply add material to the deposit, and put beads - steel balls well, if you have many who use lead shot. (Recast: [Mr_X] said that the steel balls can cause a fire!) I've used the marble. Use at least 100 balls from 1 / 2 "3 / 4" in size. Whether they are of equal size or not, in this case, experimentation is good. If gaminsit large, tractor-PTO based on the drum, and then 100 balls does not help. In order for material to be crushed to the friction between balls and it is essential that sufficient, or grinding, take a few days, not hours.
Ball Mill: power, speed and spec
Homemade Ball Mill spec
My AC motor 1750 RPM 3 / 4 hp. It has a 1-1/2 "Pulley and my kneecap is 6-1/2" in diameter. A drive axle is 5 / 8 "in diameter with a rubber hose which is 1" in diameter. My plastic vessels are 6 "in diameter.
Pulley split from a vessel = multiplicand
Multiplicand multiplied ENGINE RPM RPM = FINAL
(Cia praslydimas not included.)
Keep in mind that this is also not included the fact that the belt rotates around 1 / 2 "
from the outer disc wheel so the figure would be slightly high.
1.5 divided by 6.5 = 0.2307
0.2307 multiplied by 1750 = ~ 400 rpm
Next "round" - a 1-inch top and 6 inch drum.
Divided by 6.0 = 0,167
0,167 multiplied by ~ 400 = ~ 67 rpm
67 RPM is about one revolution per second, which is a good frequency, the contents of the roll and was not pressed centripetal force.
Upon sita as interested in or have buciau simply connected 5-gallon buckets to a large disc are, in order to get a "cement mixer". In order to do so with the 1 "disc driving my motor pulley should be 26 coliu diameter. But the disc really find his conduct the subject of bulk, but you can turn himself installations in the drum or pail slowly enough that the inside of the substance is not to have been pressed from the centrifugal force .
Really simple is made than to try to explain!
My ball mill'o production was grinding the clay which then produces a burning furnace. So the Internet looking for as I crushed the clay powder.
