Trunnion bearings in cement and grinding mills are exposed to extremes in heat, cold, rain and harsh airborne particulates. To help protect bearings against these extreme conditions and avoid possible production headaches, large amounts of grease are used to purge contaminants from trunnion housings.
On top of that, GIVA counts 6 ring rolling mills producing square section and shaped rings and shells up to 10m in diameter and 220 tons in weight. Over 30 manipulators with a capacity up to 250 tons serve the forge departments: some are free man driven, other are automatically integrated to the presses.
Depending upon available handling facilities, the head or shell can be lined separately ina repair bay, or alter assembly of the mill proper in the trunnion bearings. In the case of ball mills, all internal wearing parts will pass through the manhole, whereas in the case of open end rod mills they sill pass through the discharge trunnion opening.

With thinner inner and outer rings, these bearings keep your machines more compact than highload crossedroller bearings. Route hydraulic lines, electrical wiring, and other components through the inside of the bearing. Mounting holes on the rings allow for fastening onto hollow joints and shafts.
Ball mill trunnion replacement Drawing on years of experience and process knowledge, our trunnion replacement service combines our stateoftheart trunnion design, highquality parts and expert onsite installation teams to ensure reliable mill operation. Suitable for both FL and nonFL mills
May 25, 2023 8:55 am News The ball mill trunnion plays a crucial role in the efficient operation of cement mills, autogenous mills, and coal mills. As a key component, the mill trunnion provides support to the mill shell and ensures proper alignment, allowing the mill to function effectively.
The mill trunnion bearings are journal bearings that support the shell on both sides of the trunnion. The mill trunnion bearings are fitted with babbitted rocker inserts. Cooling is achieved by passing liters/second of cooling water at 310 kPa pressure through the coils in the liner inserts. The bearings are designed for an oilwedge ...

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 machining process So that can ensure the tolerance ...
With oilair lubrication systems, many oil types are suitable. Oils with a viscosity of 40 to 100 mm 2 /s at 40 °C (105 °F) are typically used as are oils with EP additives which are preferable, especially for roller bearings. Oils with a viscosity of 10 to 15 mm 2 /s at 40 °C (105 °F) are typically used for oil jet lubrication, whereas oil ...
The trunnion diameter is 1180 mm, the width/diameter ratio is and the moment arm is 1115 mm. A spherical roller bearing, 239/1180 CAK/W33, on a tapered seating is shown at right. The trunnion diameter is the same. To better exploit the narrowness of the spherical roller bearing, the bearing housing is offset relative to its base plate.

The trunnions also define a bearing surface for permitting rotation of the drum. The drum is filled with a charge of forged steel balls to a level just below the bottom of the trunnions. As the drum is rotated, the balls are continuously lifted and tumbled by gravity onto the coal to pulverize the coal.
Fourrow tapered roller bearings or two spherical roller bearings arranged together on a cylindrical Roll neck bearings Design conditions 4 neck have a loose fit. As a result, the chocks can be easily removed; their field of application is restricted, however, by the loose fit. If cylindrical roller bearings are fitted as radial bearings, the rolls
The base of each blade has a shaft. The blade shaft interlocks with the trunnion bearing. By a complex series of levers and gears, the blade shaft rotates in the trunnion bearing, while another part of the bearing supports the main spinning shaft. The engineering company Andritz AG, in Graz, Austria, designed such a bearing for marine propellers.
The thrust roller is an important auxiliary part of a rotary is designed to control the axial vibration of the rotary kiln, so that the tyres and rollers can be evenly distributed on the full the same time, it can ensure the linearity of the kiln body centerline, make the big and small gears mesh well, and reduce the power consumption of the kiln process.
