I am referring to is a scrubber and the use of the pedestal is due to a design flaw, since the high pressure pump should cut out after lifting the mill and leaving the low pressure pump running. We have now controlled the excessive temperature rise by adjusting the alignment of the pedestal. This is at the feed end trunnion bearing.

A dummy leg is a piece of pipe that acts as a support branch between your pipe and a nearby support point. It is generally either smaller than or the same size as the pipe you're supporting. By welding these extra pieces to your pipe run's elbow, you essentially add a support wedge that fortifies a vulnerable point in your pipe system.

Mill TRUNNION BEARINGS. The trunnion bearing assemblies can now be mounted on their sole plates. If the bearings are of the swivel type, a heavy industrial water-proof grease should be applied to the spherical surfaces of both the swivels and the bases. Move the trunnion bearings to their approximate position by adjustment of the set …

Optimising the capacity of your SAG mill is crucial to avoiding downtime and liner wear and damage. With variances in mill ore feed rate, mill speed and slurry density, critical impacts can occur in your SAG mill. The speed at which these variances are adjusted for is thus crucial for minimizing damage and optimizing liner life.

This combination is called SLURRY. If this slurry gets onto the face of the bull gear it will act like sand paper when the pinion gear and the bull gear mesh together. It takes very little time under these conditions to wear a bull gear completely out. Where the bull gear is on the mill shell will affect how you shut your equipment down.

Shell-mounted mills with end walls directly above the main bearings are generally stiffer than trunnion-mounted mills. We have checked this by comparing a 26 ft shell-mounted ball mill with a trunnion-mounted mill of equal grinding volume and same diameter. Detailed finite element models of each mill were created.

On site we have a Sag Mill Driven by a 5500KW Motor. We have a vibration issue right across the Mill. The highest vibration is 30mm/sec RMS axial on the motor n ... Now the trunnion bearing on the fixed end discharge has moved from its original position and possibly the pinion is on another position of the girth gear.

In a propeller trunnion bearing, the entire pull of the prop is on the main shaft. While the propeller is spinning and pulling, centrifugal force tries to rip the blades away from the hub. In a piece of farm equipment, the spinning shaft turns a tiller blade, but the entire blade carrier has to swing up and down to account for various terrains ...
