Ball mill trunnions and heads are subject to large alternating stresses during operation. Even though trunnions are designed for infi nite life, there is always a risk of cracks developing due to small casting defects, wear of the inner surface of the trunnion or other damage, such as cutting scars or welding in the highstressed areas.
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. ... BALL MILL FEED BOX. Ordinarily the feed box for a scoop feeder is designed and supplied by the user. The feed box should be so constructed that it has at ...
Type CHRK is designed for primary autogenous grinding, where the large feed opening requires a hydrostatic trunnion shoe bearing. Small and batch grinding mills, with a diameter of 700 mm and more, are available. These mills are of a special design and described on special request by all Ball Mill Manufacturers.
Two ball mill trunnions are installed at both ends of a ball mill, one is the feed trunnion, which is the passage for the material to be transported into the cylinder, and the other is the discharge trunnion, through which the ground material is sent out. The trunnion bearing supports the ball mill trunnion and drives the trunnion to rotate.
Oil leakage from trunnion bearing seals can cause many environmental and administrative concerns. The Metso barricade seal arrangement solves the myriad of issues around the proper sealing of grinding mill main bearings. ... Ball mill feed spouts experience constant wear and need to be changed periodically to allow ongoing operation. Our ball ...
One of our Ball Mills keeps losing pressure on the high pressure pump. It will run fine when starting the Mill and suddenly after a while sometimes 1hrs the pumps will loose pressure. We have just grinded the journal and installed new white metal bearings. After startup this afternoon after about 1hrs the pumps low and high just lost pressure.

Source #1 Damping of the elastohydrodynamic (EHD) lubrication film within the Hertzian contact zone between the rolling elements and the raceways. Source #2 Bearing interface damping between the bearing rings and housings. or shaft respectively. Source #3 Damping due to squeezing lubricant within the socalled entry.
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 high pressure oil for hydrostatic lift of the feed and discharge trunnions during startup of the mill.
Trunnion bearing for ball mill Material: Cast steel Processing Weight: 512 tons Standard: ASTM: 1025 / DIN: CK25 Get A Free Quote The ball mill trunnion bearing is a detachable loadbearing structure that sits on the sliding rings at the feed and discharge ends of the ball mill.
A trunnion mill has the trunnion bearing supporting the entire weight of the mill. Changing out a trunnion rolling element (or sleeve) bearings requires the support an entire end of the mill. Specialize cradles and lifting gear is required. With a slipper pad bearing mill, the load is distributed via 4 (or more) pads per end.
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 Ball Mill is designed to grind materials by turning the cylindrical shell with grinding medium ( steel balls, cylpeb, and pebbles) put in the shell, and has a simple structure and ease of handling. ... Trunnion bearing 6) Drum gear 7) Liner 8) Gear case 9) Combination feeder: Gratedischarge Type. 1) Shell 2) Trunnion
FSDR .. K housings are large, lowweight pillow (plummer) block housings designed specifically for grinding mills. They operate under arduous conditions in highly contaminated environments. With their highly effective sealing solution, they enable the incorporated bearing to achieve maximum service life by preventing the ingress of contaminants ...
Process specialists evaluate: Material feed Pressure, flow and temperature across the ball mill and separator circuit Ball mill charge/level Crash stop and metre samples analysis In addition, the mill trunnion and girth gear temperature is measured using a noncontact type thermometer to analyse the condition of these components.
Trunnion Bearings is an important part loading mill cylinder rotary These casting surfaces such as the neck contacted with the mill spherical tile and the circular arc neck contacted with cylinder are free of blowhole and sand inclusion in the cast process; the position parts contacted with spherical tile need to grinding after machining in mach...
Hydrostatic Trunnion Bearing Design. Hydrostatic trunnion bearings were recently provided on large SemiAutogenous Grinding (SAG) mills driven by wraparound motors assembled on the head to shell flanges. A conventional SAG mill would have a ring gear driven through one or two pinions. The effects of the magnetic air gap forces from this new SAG ...
The components of the mill that rotate on bearings are the trunnions. 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.
