The load capacity of a trunnion bearing refers to its ability to support and withstand the applied loads without failure or deformation. It is a critical aspect of bearing design, ensuring the structural integrity and …
Low Pressure /High Flow oil is circulated from a reservoir to the top of the Trunnion bearing. The low pressure oil coats the journal and other bearings surfaces, helping with oil wedge formation when rotation has been achieved. The high flow circuit will deliver the filtered and cooled oil to the bearing. LIFT & LUBE SYSTEMS
SAG mills grinding media includes some large and hard rocks, filled rate of 9% – 20%. SAG mill grind ores through impact, attrition, abrasion forces. In practice, for a given ore and equal processing conditions, the AG milling has a finer grind than SAG mills. ... Bearing. Since the power of the autogenous tumbling mill is relatively small ...

I only worked with SAG mills where the high pressure lubrication system is used at startup of the mill. But once was I worked with a Fuller 18x9 mill we had a heating problem in the bearing that was due to a deformity of the trunnion.
The cradles need to be lifted up to sit under the shell then jacks placed under the cradles. You sit the jacks on some big thick steel plate to dissipate the load a bit otherwise could punch through the concrete. You will insert the jacks between the cradle and the shell and then if you lift the cradle up off the concrete plinths the same gap.
The commercially viable and industry accepted alternate is a grate discharge trunnion supported mill or a grate discharge shell supported mill using pulp lifters. The …

5. Additionally, mill trunnion seals are essential to prevent contaminants from entering the trunnion bearing area. Proper mill trunnion seals help maintain bearing integrity and extend life. Mill trunnion seals must be designed to withstand operating conditions and effectively keep out dust, moisture and other contaminants that can affect …
Trunnion bearing housings for grinding mills – FSDR..K series. 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 ...
The size of the balls depends upon the size of the drum, typical ball sizes are two to three inches in diameter (four-inch balls are also possible). Bearings - smaller ball mills use anti-friction cylindrical roller bearings. Larger ball mills use trunnion bearings. Enjoying this article? Then be sure to check out our Engineering Video Courses!
Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW. Our team of product engineers continually improves SAG/AG Mill designs in order to provide the most …
Semi-autogenous grinding mills (SAG mills) are tumbling mills that most commonly have a shell diameter-to-length ratio of around two. With this high aspect ratio, SAG mills …
Control of the total charge and the ball charge volume is vital to the optimum performance of semi-autogenous grinding (SAG) mills to maximise throughput and energy efficiency.
Ball Mill Trunnion Bearing Lube System View Larger Image On a 11'-6" x 22'-0" Ball Mill, the trunnion bearing lubrication system provides continuous low pressure flood oil for cooling and lubrication of the bearings, and high pressure oil for hydrostatic lift of the feed and discharge trunnions during start-up of the mill.

In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rod mill or ball mill, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for …
The ball mill trunnion is located at both ends of the ball mill cylinder and plays the role of supporting and connecting the mill cylinder. Two ball mill trunnions are installed at both ends of a ball mill, one is the feed trunnion, which is the passage for the material to be transported into the cylinder, and the other is the discharge trunnion, through which the …
SKF offers solutions for autogenous mills, ball mills, high pressure grinding rolls, rod mills, SAG mils and horizontal grinding mills. The solutions are designed to protect pinions and trunnions and prevent failure in these harsh operating conditions – helping you improve reliability and safety while reducing maintenance and operating costs.
A SAG (Semi-Autogenous Grinding) mill is a giant rotating cylinder filled with grinding media and the ore being reduced. As the mill rotates, the grinding media lifts and the impact crushes the feed material. SAG mill control refers to the practice of managing the mill load, which is the amount of material inside the mill at any given time.
Excessive load puts undue stress on liners and lifters, accelerating wear and tear. Proper control extends equipment life and reduces maintenance costs. Stable …
