Trunnion Bearing Assembly Ball Mill & Rod Mill

Swivel type lead-bronze 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. The bushing is provided with end flanges thus assuring that the trunnion flanges run against a bronze face.

stresses and strains arising out of ball mill operations. The large alternating stresses placed on ball mill trunnions and heads are a great example. However a trunnion is designed to last for ever, these stresses always bring the risk of cracks developing. Keeping the mill turning Cracks in a trunnion will bring production to a standstill. When

Ball mill trunnion CHAENG

Ball mill trunnion (ball mill head) is an important part to bear cylinder of ball mill. Its main function is to support and connect cylinder, and it is also the access way for the material. The force axial meet at work is mainly bending force.

Mill Trunnion Liner Mineral Processing & Metallurgy

Smaller Ball Mills are constructed with separate trunnions; larger diameter mills have trunnions cast integral with the heads. Separate trunnions are attached to the heads with bolted flanges for male and female fit. Flanges are faced and counter bored. All trunnions are cast of Meehanite metal, turned and carefully polished. All trunnions have a large bearing surface capable of carrying the heavy mill load and to avoid heating during operation. The outer ends of the trunnions

Typical Reason to Replace a Ball Mill Trunnion

It is unclear if the trunnion damage was known ahead of time and planned for a change-out during the shell reline or if it was discovered during the reline work. While, not knowing if this is the feed or discharge end trunnion, there could be a number of things causing this emergency repair job and plant downtime:

Trunnion or Slide Shoe: Which Are Better Ball Mill

Trunnion Ball Mill Bearings are widely used in many industries due to their popularity owing from usage for decades, but when it comes to cement grinding industries, Slide Shoe bearing ball mill is preferred because of its longer retention time. 3. Having the latest self-aligning properties and compressive strength capabilities, slide shoe bearing finds application in many industries over

Analysis of the criticality of flaws found in trunnion of

The structural components of a mill, basically, shell, heads and trunnions, besides high costs, have lead times that might reach three years, according to market demand. Therefore, it becomes increasingly necessary that any flaws in those components to be properly evaluated. This paper analyzed the fracture mechanics of flaws, such as cracks observed in a ball mill trunnion and compared the

Trommel Magnets and Trunnion Magnets WPE Process

The Trunnion Magnet System bolts directly to the ball mill discharge flange to provide continuous magnetic collection of the grinding ball fragments. A permanent magnetic circuit collects the grinding ball fragments and discharges them to a collection hopper. Grinding ball fragments discharging from ball mills cause extreme wear to downstream processing equipment. These ball fragments

Analysis of the criticality of flaws found in trunnion of

01/03/2016 The cracks to be analyzed in this study appeared in a trunnion of a ball mill in the region of axial and radial contact with the bearing bushing of the mill. Those cracks were caused by a lack of lubrication, which allowed the metal to metal contact between the trunnion and the bushing. This contact led to a heating in the trunnion, inducing thermal stresses that culminated in the appearance
