trunnion bearing assembly ball mill & rod mill

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.

what are the main factors that decrease the output of raymond mills? - deya machinery

Recently, one of our customers consulted some problems of Raymond Mill. He said that the output of his original old equipment declined when producing stone powder, which serious affected the production efficiency.

The feeding speed of Raymond mill can not be too fast or too slow, too much material will affect the performance of equipment, and too little material leads to mill idling, thus seriously affecting the production capacity.

Damage to any part will have a greater impact on the final output. Thereforefan, grinding roller and other important parts should be checked on time to find the problem and solve in time to ensure the normal operation of the equipment.

Large material moisture is the main reason for the decrease of stone powder production, which not only increases the difficulty of milling, but also makes the materials easier to plug the powder channel, thus leading to unsmooth work of grinding mill and resulting in a decline in production capacity.

Raymond Mill mainly achieves the grinding process replying on grinding roller and ring. If the damage is serious, then the material will not be ground to the user's desired fineness, and will continue to cycle in the mill, resulting in a decline in production.
