Trunnion assemblies connect to the vessel and sense the liquid level, moving a lever up and down, linking to and operating a lever operated dump valve. A float and float arm must also be ordered separately to complete the trunnion assembly. Skip to …

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.

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.

FSDR .. K housings are large, low-weight 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 …

The oil level can be seen at any time during operation to replenish the oil in time and avoid the occurrence of bearing damage accidents. AGICO trunnion bearing is made of ZG35 and ZG45 cast steel, which has high hardness, excellent wear resistance, strong bearing force, and small loss. It can work continuously for a long time.

Mill Trunnion Liner. 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. The difference in the trunnions at each end of the mill isn't in the trunnions … See more

After the usual type of trunnion bearing the mill consists of a short conical section showing a sharp drop from feed entrance to maximum mill radius. A cylindrical section of varying length then follows and toward the discharge end connects with a comparatively long and conical section sloping, at considerably less pitch than at the …

CERAMIC LINED BALL MILL. Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.

Martin Manufacturing, a family owned business, was founded in 1991 by Stan Martin. The company was a humble, two door garage shop when Stan designed the first trunnion table. His only goal in mind was to increase the efficiency of his own business, and it did exactly that by making the company's worst paying jobs its most profitable.

Processing Weight: 5-45T. The ball mill trunnion, also known as the hollow shaft is an important part of the ball mill that carries the rotation of the ball mill barrel. It is a special type of steel casting. It mainly plays the role of supporting and connecting the cylinder in the whole ball mill, and is the entry and exit channel of the material.

Hydrostatic Trunnion Bearing Design. Hydrostatic trunnion bearings were recently provided on large Semi-Autogenous 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 …
