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 ground material is sent out.

Cement Ball Mills. A cement ball mill is designed to grind clinker, gypsum and for the drying of cement additives. It is a component in the cement making process. Today's Ball Mills are typically designed with a slide shoe bearing. These bearings have replaced the more traditional trunnion bearings, as they are less expensive to purchase and ...
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 startup of the mill. System monitors including pressure switches and flow monitors are provided, along with temperature sensors that monitor ...
With the design criteria established the following repair/reinforcement procedures were performed. Initially the mill was jackedup to remove the weight of the mill and the charge from the trunnion. The sections in the upper half of the trunnion that either exhibited cracking or were less than (.75″) thick were removed.

One of our Ball Mills keeps losing pressure on the high pressure pump. It will run fine when starting the Mill and suddenly after a while sometimes 1hrs the pumps will loose pressure. We have just grinded the journal and installed new white metal bearings. After startup this afternoon after about 1hrs the pumps low and high just lost pressure.

Ball mill trunnions and heads are subject to large alternating stresses during operation. Even though trunnions are designed for infi nite life, there is always a risk of cracks developing due to small casting defects, wear of the inner surface of the trunnion or other damage, such as cutting scars or welding in the highstressed areas.
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. Help is at hand with SKF trunnion support housings that deliver optimal results: Extend trunnion bearing service life. Reduce maintenance costs. Reduce grease consumption.
