cheap and simple ball mill : 10 steps - instructables

Last year for the Fourth of July, I wanted to make some black powder to celebrate American freedom with a bang. However, one step in the manufacture of black powder is running it in a ball mill to grind it into a fine powder. I was not in possession of a ball mill, and Independence Day was quickly approaching, so I decided to make my own.

First, cut your PVC pipe to your desired length with the hacksaw. I cut mine to 6 inches. Then cut the threaded rod with the hacksaw based on the length of your pipe. It will need to be about 3 inches longer than the pipe, leaving room for the adapter, screw cap, and wing nut on one end, and the cap, nut, and half of the coupling nut on the other end.

Wrap the small rag around the threaded rod, and clamp the locking pliers around it. This serves to hold the rod still while you work the locking nuts onto the rod with a wrench. The rag is simply to protect the threads from getting disfigured by the pliers. You'll probably have to play around with how thick the rag is and how tight the pliers are to keep the threaded rod from rotating inside. Start one of the nylon locking nuts onto the end of the rod, and use the wrench to work it down the length of the rod. You'll want to go down just far enough so that you can fit the screw cap over it and have just enough room for the wing nut to tighten over the cap. Start another nylon locking nut on the opposite end of the rod. This nut will need to go down a bit farther, so that the flat cap will fit over it, and so that there's enough rod left to thread a second locking nut and half of the coupling nut.

The shank end of the mill will have the shank used to rotate the mill.Note:I changed my design after the initial build and I neglected to retake the pictures. The images are slightly inaccurate and show the screw cap instead of the flat cap on the shank end of the mill, but just pretend it's the flat cap. Feed the long end of the threaded rod through the hole in the flat cap. Using the same technique as in the previous step, thread a second nylon locking nut over the cap and tighten it down to hold it in place. Then thread half of the coupling nut onto the remaining portion of the rod.

Now you'll need to make the shank that allows a drill or something with a chuck to hold the mill and rotate it. First, install the hex bolt into the coupling nut with a wrench until it's very tight. All the threads should be inside the coupling nut, with just the bare rod of the bolt exposed. Then clamp down the mill and use the hacksaw to cut off the hex head of the bolt, leaving behind the smooth rod of the bolt. Congratulations, you made a shank! (But not the kind you kill people with in prison.)

Note:If you decide to use PVC cement, now is the time to get that out. Slide your PVC pipe into the cap on the shank end. If you choose to use cement, apply it here. Then slide the male screw adapter onto the other end of the pipe. (This is your second chance to use the cement and smell those fumes.)

For lack of a better term, I'm calling this end the mouth. It's the end you open to put in and empty out your powder (or whatever you choose to mill). Screw the female screw cap onto the male screw adapter until it butts up against the locking nut on the rod. Then thread the wing nut onto the remaining length of rod and tighten it down to hold the screw cap in place.

Now you get to put your new ball mill to use. Try to find some lead balls, since they are heavy and won't spark. I was unable to get lead balls at the time and tried using plastic BBs, but those are much too light to do any work. I was able to have some success using glass beads though (marbles would work too). First, remove the wing nut on the mouth end, then unscrew the cap.Load up the mill with some balls and fill it with your material to be milled.Note:Don't fill up the mill all the way, or it won't have any room to do it's job! Use plenty of balls and leave plenty of room for tumblin'. Screw the cap back on and reinstall the wing nut, fit it to your motor of choice, and let it grind!

I like it, nice and simple. I have considered making my own black powder for use in my cannons. For the most part I have talked my self out of it. Everything I have read has indicated consistency problems with home made powder. But at $16 a lb plus hazmat fees it can get expensive in a hurry when you start using 1/4 lb or more per shot.

trunnion bearing assembly ball mill & rod mill

The first part of the mill that we will look at is the TRUNNION BEARING.This is a HYDROSTATIC BEARING which is a slow moving bearing that carries a heavy load. Usually it is constructed from Babbitts metal. If you happen to remember the introduction to this course Issac Babbitt was the man who devised the method of bonding self-lubricating metals onto a strong backing to form a bearing. This type of bearing is named after him. Let us start with the base of this bearing. In it you will notice a SUMP for oil and an oil line that is connected to a PUMP. In the centre of the base is the BEARING SEAT. There is a hole in the middle of the bearing seat to allow the oil from the oil line to come out of. Radiating away from this hole there are OIL CHANNELS. These are simply grooves cut into the metal to allow the oil to be dispersed over the face of the bearing.

Now this is important, as I mentioned, this is a hydrostatic bearing, it supports a great weight. Because it has a great weight on it, when it is stopped, the oil is squeezed out from between the inner and outer bearing. Before the mill is started up this bearing must have oil injected into it by way of a pump. The pump must be started before the mill begins to turn and must continue until the mill has made at least one revolution. After that one revolution, what is known as the wedge effect, takes place. The oil that is on the surface of the bearing is forced into a wedge shaped portion of the leading edge of the outer bearing. This will generate enough pressure to lift the entire mill. But if the pump isnt kept pumping for that revolution the weight of the mill as it turns will force the metal of the bearing surface into the oil channels. Two of the required characteristics of these bearings are that they resist dirt contamination and disperse heat well. The result is that the material that the bearing is constructed from is soft. If an oil film isnt present between the two bearing surfaces, the metal to metal contact will cause this damage to the oil channels. Then the bearing will not be able to get enough oil on start up. In extreme cases the bearing may be destroyed.

Once the mill is turning the bearing is self-lubricated by OIL RINGS. They should be checked periodically. If you look closely at them you will notice that they have holes in them. As the rings revolve with the bearing these holes pickup oil from the SUMP in the bearing base and carries it to the top of the bearing. This ring is not joined to the bearing but sits on it loosely.

Because of the drag on the ring by the oil in the sump as the ring is revolved through it, and the lubrication of the oil between the ring and the bearing, the ring turns at a slower rate than the mill does. This is necessary to allow the oil to flow out from under the ring and get caught at the contact point of the inner bearing and the outer bearing. The outer bearing then picks up this oil and maintains the wedge effect.

This cap provides access to the rings and the inner bearing by two ACCESS DOORS on top of the cap. When the bearing and rings are checked through these ports, the person doing the inspecting will be looking at the condition of the bearing surface, verifying that the bearing is being oiled, and that it is free from any grooves or gouges. At the same time, check the rings to be sure they are turning, but at a slower rate than the bearing is.

There is one more piece to complete the assembly, technically it belongs with a following section on liner description, but to avoid confusion I will include it in this portion. It is the TRUNNION LINER, it fits inside the bearing to protect it from wear caused by the ore being washed over the liner and through the bearing as it is fed to or discharged from the mill.

Swivel type lead-bronze bushed trunnion bearings are generally furnished on large diameterball Mills. The bearing swivels are of Meehanite metal spherically turned outside and bored and faced inside to receive the removable bushing. The bushing is bored and scraped to fit the mill trunnion. The bushing is provided with end flanges thus assuring that the trunnion flanges run against a bronze face.

On smaller mills rigid or swivel type bearings support the mill trunnions. The lower half of such bearings are lined with bronze or a special millbabbitt which is peened in place and bored to fit the trunnion.

In all cases a low bearing pressure is maintained to assure freedom from overheating, long life and minimum maintenance. They are designed to provide support to the mill proper, its media and pulp load.

In many dry grinding applications, or where heat is developed, the trunnion bearings can be furnished for water cooling. This system carries away the excess heat transmitted through bearings and protects them.

Lead Bronze has been found to be the most satisfactory bearing material for large diameter bearings, affording the greatest protection against damage of trunnions. Lead bronze will withstand extreme heat for a considerable period of time (for example in the event of lubrication failure). Such heat will cause the lead to sweat out and act as a lubricant itself. This protection eliminates the possibility of scoring a trunnion and there is no danger, as with babbitt, of having the trunnions settle in the bearing and rub on the bearing base.

These are cast heavy in section of Meehanite metal. Where swivel type bearings are used the base is spherically bored inside to gauge to receive such swivels. The bottom of the base is planed to fit a planed top of the trunnion bearing sole plate. The bearing cap is provided with a shroud feature extending out over drip flanges to protect the bearing from entrance of dirt or grit.

Slotted holes are provided in the base for bolting the base to the sole plate; this permits movement of the bearing on the sole plate for adjustment of gear and pinion mesh. Such adjustment is carried out by the use of set screws.

A separate hand operated lubricant jack can be furnished to be mounted on the bearing base or at some distant point to provide a flow of lubricant prior to starting mill rotation. This feature assures lubricant being present at the bottom of the bearing and reflects somewhat in reducing bearing wear and shows a slight reduction in starting torque.

Pinion shaft bearings are of the SKF anti-friction type mounted in a common twin bearing assembly. Bearings are fixed in place so that the pinion shaft of the mill is always in alignment with the drive components. V-belt driven mills are furnished with an outboard bearing of similar construction.

Also available are bearings of the double rigid ring oiling type for special applications. Such bearings are cast integral with a heavy twin bearing sole plate assuring perfect alignment and rigidity. These bearings are equipped with bronze or babbitted bushings.
