The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...
In addition, a cultural change took place at the mill. Plant personnel recognized the importance of lubrication, and there was an increase in morale for the lube technicians. The reliability of the mill's lubrication system also improved from 4.58 to 55.51 percent per month, making the company's relatively small investment well worthwhile.

It reduces inventory by accommodating both hot and cold-water service, and is designed for quick, easy maintenance. Apply the 221 Series with confidence in high and low-temperature ...
A good suggestion is to run mill for eight hours under no load, then increase load slowly over a 24-hour period. Check contact pat-tern and lubrication patterns every 2-4 hours. When partially or fully loaded, some deflection will occur; continue to check contact and lube patterns every 2-4 hours and make alignment corrections as required.
On a 11'-6" x 22'-0" Ball Mill, the trunnion bearing lubrication system provides continuous low pressure flood oil for cooling and lubrication of the bearings, and …

The mine is closed and now you need to know how to put the SAG or Large Ball Mill in care and maintenance does not have to be complicated to the point where you need bridge erection equipment for lifting a Mill (AG/SAG/Rod/Ball). You actually need to lift a car higher than a mill. All you need to do is jack the mill up about 1/2″.
The mill trunnion bearings are a key assembly in mill operation. If the trunnion bearings are not reliable the complete mill is …
I only worked with SAG mills where the high pressure lubrication system is used at startup of the mill. But once was I worked with a Fuller 18x9 mill we had a heating problem in the bearing that was due to a deformity of the trunnion.

High temperature of the ball mill will affact the efficiency. 3 For every 1% increase in moisture, the output of the ball mill will be reduced by 8% -10%. 4 when the moisture is greater than 5%, the ball mill will be unable to perform the grinding operation. 5. The bearing of the ball mill is overheated and the motor is overloaded.

The Mill Trunnion Liner 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. The difference in the trunnions at each end of the mill isn't in the trunnions themselves. The trunnion liner on the feed end of the mill may have a WORM to ...
The trunnion is a kind of cylindrical and tubular shaft with thick walls, wherein the ore passes through its inner diameter, both in the feed and in the mill discharge. A pressurized oil film prevents metal to metal contact between the trunnion and the bearing bushing and allows the mill to rotate without excessive friction.

Trunnion bearings are very specialized bearing mechanisms. Sometimes, a shaft not only has to rotate, but the assembly connected to the shaft has to rotate as well. Other times, the shaft has to be free to move around in circular motions. Your shoulder joint is a trunnion bearing. Its a a ball-and-socket assembly, allowing your arm to rotate ...
To predict the power of the SAG mill, ... the data related to the trunnion oil outlet pressure, motors power, feed load, water ratio (the ratio of ore mass to the total mass of the mill contents), water flow rate and electric ear (noise) have been collected from the control room of the plant. It is noted that for all measurements, the mill ...
