Ball mill trunnion repair. Due to the geometry of the bearing housing, the lower half of the ball mill trunnion was only approximately accessible for repair. The design criteria established the distance between scalloped areas. ... but the mill operator had a fault that allowed the trunnion to run without any oil film. This deterioration ...
The ball mills are rotary equipment used in mining plants in grinding, which uses steel balls to reduce the particle size of the ore as shown in Fig. 1. The rotating assembly of the mill is supported by two bearings, called trunnion bearings indicated in Fig. 2. The bearings are static components having bushings, on which the mill rotates.
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.

Ball Mill TRUNNION BEARINGS. Swivel type leadbronze bushed trunnion bearings are generally furnished on large diameter ball 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.
Depending upon available handling facilities, the head or shell can be lined separately in a repair bay, or after 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 will pass through the discharge trunnion opening.
What are the effects on temperature of the trunnion bearing when the high pressure pump is run continuously? ... the temperature of the bearing in any way under normal circumstances unless the oil gets hot due to being recirculated without the cooler/tank etc. ... Scrubbers do not have trunnion typical ball mill/SAG mills do.
